We want to make sure appliance repair techs can get their jobs done right, safely, and efficiently by showing up with the right tools. This list is informed by years of appliance repair experience, as well as recommendations from industry veterans.

Disclaimer: This list is a great place to start and works for many repair jobs, but be aware that some require specialized tools not shown here.

1) Rechargeable Flashlight: Might seem obvious, but many repair jobs require working in tight spaces with limited natural/environmental light. Never worry about needing to replace batteries while on a job with a rechargeable flashlight, like this one you can find on Amazon.

2) Pocket Thermometer: Check that your refrigerator and freezer temperature-related repairs are complete with this pocket-size tool.

3) Utility Knife: Designed to be a lightweight, multi-purpose cutting tool, this knife will help with marking cut lines, trimming plastic or wood materials, or to cutting tape, cords, strapping, cardboard, or other packaging material.

4) Screwdriver Set: One of the most used appliance repair tools. Be prepared for any job by purchasing a battery-operated driver with Phillips head 1/4”, 5/16”, 3/8” magnetic nut drivers plus T10, T15, and T20 Torx drivers. Today’s battery-operated drivers will last a week without a recharge.

Just in case the battery-operated unit conks out, I recommend having Phillips and flat head screwdrivers both large and small in reserve.

5) Wrench Set: As with your screwdriver and nut driver sets, you’ll want to have an SAE and Metric-compatible wrench set. While they are seldom used and never carried into a customer’s house, they are kept in reserve.

6) Adjustable Wrench: This wrench features a jaw that is adjustable to accommodate various bolt and nut sizes. It’s particularly helpful with hard-to-reach fasteners.

7) Analog Multimeter: A tool that measures electrical voltage, resistance, and current, and is essential for diagnosing electrical problems. As Uncle Harry preaches I have found an analog multimeter far more useful and less misleading than a digital one.

8) Needlenose Pliers and Wire Cutters: Two other tools that you’ll want to have are a set of needlenose pliers and wire cutters. The first is great for dealing with small pieces, as well as bending or cutting wires. The second is pretty self-explanatory.

9) Putty Knife: Along with being used for spreading putty, this tool can aid in scraping and prying.

10) Rubber Gloves: Protect your hands from the combination of brute strength required and the endless sharp edges of sheet metal surrounding your hands (not to mention exposed screws).

11) Pipe Thread Sealant: Use this stuff on appliances’ threaded pipe fittings to prevent leaks. Sets quickly and firmly bonds to various materials, such as PVC, steel, and copper.

12) Telescoping Magnetic Pick-Up Tool: Spare yourself some headaches and time by purchasing this tool. It can save your life when you drop odd sized screws down into hard to reach spots of the appliance. This is a must-have.

13) 8′ Test Cord: A standard household extension cord with the female end cut off and insulated alligator clips soldered on.

14) Turkey Baster and Hand-Held Steamer: Use these tools for refrigerator-specific jobs where the drain plug is freezing and causing a blockage. It’ll help you effectively melt the ice and complete a service call in no-time.

Let’s face it. As a parent, you do not know everything that you need to know to be able to help your student with their studies. While you may have had an excellent education background, there are still areas that you are not familiar with when it comes to the things that your student is learning. The syllabus changes every couple of years, and the level of difficulty of what our children is studying even at tender ages is frightening.

Without a doubt, children who are left alone to cope with their schoolwork are struggling, especially when they are competing with their peers who may be receiving help from multiple sources. Thus, parents today are increasingly considering giving their child help through hiring home tutors. Home tutors can greatly help your child by providing extra guidance with schoolwork and by providing additional practice through tuition assignments.

Some parents nevertheless decide to take matters in their own hands and try to tutor their child on their own. One of the downsides that you will see by trying to avoid having tuition, especially in countries such as Singapore, is that your student will be limited to your own knowledge. Even though you may have a great deal of it to offer, tuition will be able to specifically help your child in the areas that they are struggling the most.

When education is tough and necessary like in Singapore, tuition is a great tool because it is difficult to keep up to date with everything that our students are learning in school. For many, our education regarding certain fields of study stops after we finish school. Furthermore, we possess limited knowledge and often while we think we remember most of the information we have learned in the past and present, we will remember everything that we have ever learned about it. With the mounting responsibilities of a parent, it is hardly possible to outdo a dedicated home tutor who keeps up to date with the latest trends that are available regarding their field of study.

Home tutors are a great way to let parents sit back and allow a professional to help their student when they need it the most. They also help students with areas where the parent is not familiar or lacks knowledge about. Having tuition and assignments are crucial for the success of a struggling student and parents should seek them out quickly so that the student does not fall behind in class.

So, when you find that your student is struggling in class, don’t hold them back by only providing them with the information that you have. Instead, rely on tuition assignments to help them develop the skills necessary to be successful. Tuition will help you to provide the correct information to your student in a way that they understand it.

One of the ways you can hire a reliable home tutor is to engage an online tuition agency. Such tuition agencies often provides tutors that have the knowledge, training and education to best help your children. Select larger tuition agencies as they often handle dozens of tuition assignments daily, making them more experienced and equipped to help you.

People around the world rely on tuition to help their chilren find their way when they have strayed from the education path. Tuition is a fantastic tool that parents should rely on so that their students can prepare for the future.

General Dynamics F-16 Fighting Falcon

The General Dynamics F-16 Fighting Falcon is a multirole jet fighter aircraft originally developed by General Dynamics for the United States Air Force (USAF). Designed as a lightweight day fighter, it evolved into a successful all-weather multirole aircraft. Over 4,400 aircraft have been built since production was approved in 1976. Though no longer being purchased by the U.S. Air Force, improved versions are still being built for export customers. In 1993, General Dynamics sold its aircraft manufacturing business to the Lockheed Corporation, which in turn became part of Lockheed Martin after a 1995 merger with Martin Marietta.

The Fighting Falcon is a dogfighter with numerous innovations including a frameless bubble canopy for better visibility, side-mounted control stick to ease control while maneuvering, a seat reclined 30 degrees to reduce the effect of g-forces on the pilot, and the first use of a relaxed static stability/fly-by-wire flight control system that makes it a highly nimble aircraft. The F-16 has an internal M61 Vulcan cannon and has 11 hardpoints for mounting weapons, and other mission equipment. Although the F-16’s official name is “Fighting Falcon”, it is known to its pilots as the “Viper”, due to it resembling a viper snake and after the Battlestar Galactica Colonial Viper starfighter.

In addition to USAF active, reserve, and air national guard units, the aircraft is used by the USAF aerial demonstration team, the U.S. Air Force Thunderbirds, and as an adversary/aggressor aircraft by the United States Navy. The F-16 has also been procured to serve in the air forces of 25 other nations.

Experience in the Vietnam War revealed the need for air superiority fighters and better air-to-air training for fighter pilots. Based on his experiences in the Korean War and as a fighter tactics instructor in the early 1960s Colonel John Boyd with mathematician Thomas Christie developed the Energy-Maneuverability theory to model a fighter aircraft’s performance in combat. Boyd’s work called for a small, lightweight aircraft with an increased thrust-to-weight ratio. In the late 1960s, Boyd gathered a group of like-minded innovators that became known as the Fighter Mafia and in 1969 they secured DoD funding for General Dynamics and Northrop to study design concepts based on the theory.

Air Force F-X proponents remained hostile to the concept because they perceived it as a threat to the F-15 program. However, the Advanced Day Fighter concept, renamed F-XX gained civilian political support under the reform-minded Deputy Secretary of Defense David Packard, who favored the idea of competitive prototyping. As a result in May 1971, the Air Force Prototype Study Group was established, with Boyd a key member, and two of its six proposals would be funded, one being the Lightweight Fighter (LWF). The Request for Proposals issued on 6 January 1972 called for a 20,000-pound (9,100 kg) class air-to-air day fighter with a good turn rate, acceleration and range, and optimized for combat at speeds of Mach 0.6–1.6 and altitudes of 30,000–40,000 feet (9,100–12,000 m). This was the region where USAF studies predicted most future air combat would occur. The anticipated average flyaway cost of a production version was $3 million. This production plan, though, was only notional as the USAF had no firm plans to procure the winner.

Five companies responded and in 1972, the Air Staff selected General Dynamics’ Model 401 and Northrop’s P-600 for the follow-on prototype development and testing phase. GD and Northrop were awarded contracts worth $37.9 million and $39.8 million to produce the YF-16 and YF-17, respectively, with first flights of both prototypes planned for early 1974. To overcome resistance in the Air Force hierarchy, the Fighter Mafia and other LWF proponents successfully advocated the idea of complementary fighters in a high-cost/low-cost force mix. The “high/low mix” would allow the USAF to be able to afford sufficient fighters for its overall fighter force structure requirements. The mix gained broad acceptance by the time of the flyoff between the prototypes, and would define the relationship of the LWF and the F-15.

The first YF-16 was rolled out on 13 December 1973, and its 90-minute maiden flight was made at the Air Force Flight Test Center (AFFTC) at Edwards AFB, California, on 2 February 1974. Its actual first flight occurred accidentally during a high-speed taxi test on 20 January 1974. While gathering speed, a roll-control oscillation caused a fin of the port-side wingtip-mounted missile and then the starboard stabilator to scrape the ground, and the aircraft then began to veer off the runway. The GD test pilot, Phil Oestricher, decided to lift off to avoid crashing the machine, and safely landed it six minutes later. The slight damage was quickly repaired and the official first flight occurred on time. The YF-16’s first supersonic flight was accomplished on 5 February 1974, and the second YF-16 prototype first flew on 9 May 1974. This was followed by the first flights of the Northrop’s YF-17 prototypes on 9 June and 21 August 1974, respectively. During the flyoff, the YF-16s completed 330 sorties for a total of 417 flight hours; the YF-17s flew 288 sorties, covering 345 hours.

Increased interest would turn the LWF into a serious acquisition program. North Atlantic Treaty Organization (NATO) allies Belgium, Denmark, the Netherlands, and Norway were seeking to replace their F-104G fighter-bombers. In early 1974, they reached an agreement with the U.S. that if the USAF ordered the LWF winner, they would consider ordering it as well. The USAF also needed to replace its F-105 and F-4 fighter-bombers. The U.S. Congress sought greater commonality in fighter procurements by the Air Force and Navy, and in August 1974 redirected Navy funds to a new Navy Air Combat Fighter (NACF) program that would be a navalized fighter-bomber variant of the LWF. The four NATO allies had formed the “Multinational Fighter Program Group” (MFPG) and pressed for a U.S. decision by December 1974. The U.S. Air Force then advanced its plans to announce the LWF winner from May 1975 to the beginning of the year, and accelerated testing.

To reflect this more serious intent to procure a new fighter-bomber design, the LWF program was rolled into a new Air Combat Fighter (ACF) competition in an announcement by U.S. Secretary of Defense James R. Schlesinger in April 1974. Schlesinger also made it clear that any ACF order would be for aircraft in addition to the F-15, which extinguished opposition to the LWF. ACF also raised the stakes for GD and Northrop because it brought in further competitors intent on securing the lucrative order that was touted at the time as “the arms deal of the century”. These were Dassault-Breguet’s Mirage F1M-53, the SEPECAT Jaguar, and a proposed derivative of the Saab 37 Viggen named the “Saab 37E Eurofighter”. Northrop offered the P-530 Cobra, which was very similar to its YF-17. The Jaguar and Cobra were dropped by the MFPG early on, leaving two European and the two U.S. candidates. On 11 September 1974, the U.S. Air Force confirmed firm plans to place an order for the winning ACF design sufficient to equip five tactical fighter wings. On 13 January 1975, Secretary of the Air Force John L. McLucas announced that the YF-16 had been selected as the winner of the ACF competition.

The chief reasons given by the Secretary for the decision were the YF-16’s lower operating costs, greater range and maneuver performance that was “significantly better” than that of the YF-17, especially at near-supersonic and supersonic speeds. Another advantage was the fact that the YF-16 – unlike the YF-17 – employed the Pratt & Whitney F100 turbofan engine, which was the same powerplant used by the F-15; such commonality would lower the unit costs of engines for both programs.

Shortly after selection of the YF-16, Secretary McLucas revealed that the USAF planned to order at least 650 and up to 1,400 of the production F-16 version. In the Navy Air Combat Fighter (NACF) competition, the Navy announced on 2 May 1975 that it selected the YF-17 as the basis for what would become the McDonnell Douglas F/A-18 Hornet.

The U.S. Air Force initially ordered 15 “Full-Scale Development” (FSD) aircraft (11 single-seat and four two-seat models) for its flight test program, but this was reduced to eight (six F-16A single-seaters and two F-16B two-seaters). The YF-16 design was altered for the production F-16. The fuselage was lengthened by 10.6 in (0.269 m), a larger nose radome was fitted to house the AN/APG-66 radar, wing area was increased from 280 sq ft (26 m2) to 300 sq ft (28 m2), the tailfin height was decreased slightly, the ventral fins were enlarged, two more stores stations were added, and a single side-hinged nosewheel door replaced the original double doors. These modifications increased the F-16’s weight approximately 25% over that of the YF-16 prototypes.

Manufacture of the FSD F-16s got underway at General Dynamics’ Fort Worth, Texas plant in late 1975, with the first example, an F-16A, being rolled out on 20 October 1976, followed by its first flight on 8 December. The initial two-seat model achieved its first flight on 8 August 1977. The initial production-standard F-16A flew for the first time on 7 August 1978 and its delivery was accepted by the USAF on 6 January 1979. The F-16 was given its formal nickname of “Fighting Falcon” on 21 July 1980, entering USAF operational service with the 388th Tactical Fighter Wing at Hill AFB on 1 October 1980.

On 7 June 1975, the four European partners, now known as the European Participation Group, signed up for 348 aircraft at the Paris Air Show. This was split among the European Participation Air Forces (EPAF) as 116 for Belgium, 58 for Denmark, 102 for the Netherlands, and 72 for Norway. These would be produced on two European production lines, one in the Netherlands at Fokker’s Schiphol-Oost facility and the other at SABCA’s Gossellies plant in Belgium; production would be divided among them as 184 and 164 units, respectively. Norway’s Kongsberg Vaapenfabrikk and Denmark’s Terma A/S also manufactured parts and subassemblies for the EPAF aircraft. European co-production was officially launched on 1 July 1977 at the Fokker factory. Beginning in mid-November 1977, Fokker-produced components were shipped to Fort Worth for assembly of fuselages, which were in turn shipped back to Europe (initially to Gossellies starting in January 1978); final assembly of EPAF-bound aircraft began at the Belgian plant on 15 February 1978, with deliveries to the Belgian Air Force beginning in January 1979. The Dutch line started up in April 1978 and delivered its first aircraft to the Royal Netherlands Air Force in June 1979. In 1980 the first aircraft were delivered to the Royal Norwegian Air Force by SABCA and to the Royal Danish Air Force by Fokker.

Since then, a further production line has been established at Ankara, Turkey, where Turkish Aerospace Industries (TAI) has produced 232 Block 30/40/50 F-16s under license for the Turkish Air Force during the late 1980s and 1990s, and has 30 Block 50 Advanced underway for delivery from 2010; TAI also built 46 Block 40s for Egypt in the mid-1990s. Korean Aerospace Industries opened another production line for the KF-16 program, producing 140 Block 52s from the mid-1990s to mid-2000s. If India selects the F-16IN for its Medium Multi-Role Combat Aircraft procurement, a sixth F-16 production line will be established in that nation to produce at least 108 fighters.

One change made during production was the need for more pitch control to avoid deep stall conditions at high angles of attack, this issue was known about in development but had originally been discounted. Model tests of the YF-16 conducted by the Langley Research Center revealed a potential problem, but no other laboratory was able to duplicate it. YF-16 flight tests were not sufficient to expose the issue, it required later flight testing on the FSD aircraft to demonstrate there was a real concern. In response, the areas of the horizontal stabilizer were increased 25%; this so-called “big tail” was introduced on the Block 15 aircraft in 1981 and retrofitted later on earlier production aircraft. Besides significantly reducing (though not eliminating) the risk of deep stalls, the larger horizontal tails also improved stability and permitted faster takeoff rotation.

In the 1980s, the Multinational Staged Improvement Program (MSIP) was conducted to evolve new capabilities for the F-16, mitigate risks during technology development, and ensure the aircraft’s worth. The program upgraded the F-16 in three stages. The MSIP process permitted the introduction of new capabilities quicker, at lower costs and with reduced risks, compared to traditional independent programs to upgrade and modernize aircraft. The F-16 has been involved in other upgrade programs including service life extension programs in the 2000s.

The F-16 is a single-engined, supersonic, multi-role tactical aircraft. The F-16 was designed to be a cost-effective combat “workhorse” that can perform various kinds of missions and maintain around-the-clock readiness. It is much smaller and lighter than its predecessors, but uses advanced aerodynamics and avionics, including the first use of a relaxed static stability/fly-by-wire (RSS/FBW) flight control system, to achieve enhanced maneuver performance. Highly nimble, the F-16 can pull 9-g maneuvers and can reach a maximum speed of over Mach 2.

The Fighting Falcon includes innovations such as a frameless bubble canopy for better visibility, side-mounted control stick to ease control during combat maneuvers, and reclined seat to reduce the effect of g-forces on the pilot. The F-16 has an internal M61 Vulcan cannon in the left wing root and has 11 hardpoints for mounting various missiles, bombs and pods. It was also the first fighter aircraft purpose built to sustain 9-g turns. It has a thrust-to-weight ratio greater than one, providing power to climb and accelerate vertically.

Early models could also be armed with up to six AIM-9 Sidewinder heat-seeking short-range air-to-air missiles (AAM), including a single missile mounted on a dedicated rail launcher on each wingtip. Some variants can also employ the AIM-7 Sparrow medium-range radar-guided AAM, and more recent versions can be equipped with the AIM-120 AMRAAM. It can also carry other AAM; a wide variety of air-to-ground missiles, rockets or bombs; electronic countermeasures (ECM), navigation, targeting or weapons pods; and fuel tanks on eleven hardpoints – six under the wings, two on wingtips and three under the fuselage.

The F-16 design employs a cropped-delta planform incorporating wing-fuselage blending and forebody vortex-control strakes; a fixed-geometry, underslung air intake inlet supplying airflow to the single turbofan jet engine; a conventional tri-plane empennage arrangement with all-moving horizontal “stabilator” tailplanes; a pair of ventral fins beneath the fuselage aft of the wing’s trailing edge; a single-piece, bird-proof “bubble” canopy; and a tricycle landing gear configuration with the aft-retracting, steerable nose gear deploying a short distance behind the inlet lip. There is a boom-style aerial refueling receptacle located a short distance behind the rear of the canopy. Split-flap speedbrakes are located at the aft end of the wing-body fairing, and an arrestor hook is mounted underneath the aft fuselage. Another fairing is situated at the base of the vertical tail, beneath the bottom of the rudder, and is used to house various items of equipment such as ECM gear or drag chutes. Several later F-16 models, such as the F-16I variant of the Block 50 aircraft, also have a long dorsal fairing “bulge” that runs along the “spine” of the fuselage from the rear of the cockpit to the tail fairing; these fairings can be used to house additional equipment or fuel.

The air intake was designed to be “far enough forward to allow a gradual bend in the air duct up to the engine face to minimize flow losses and far enough aft so it wouldn’t weigh too much or be too draggy or destabilizing.”

The F-16 was designed to be relatively inexpensive to build and much simpler to maintain than earlier-generation fighters. The airframe is built with about 80% aviation-grade aluminum alloys, 8% steel, 3% composites, and 1.5% titanium. Control surfaces such as the leading-edge flaps, tailerons, and ventral fins make extensive use of bonded aluminum honeycomb structural elements and graphite epoxy laminate skins. The F-16A had 228 access panels over the entire aircraft, about 80% of which can be reached without work stands. The number of lubrication points, fuel line connections, and replaceable modules was significantly reduced compared to its predecessors.

Although the USAF’s LWF program had called for an aircraft structural life of only 4,000 flight hours, and capable of achieving 7.33 g with 80% internal fuel, GD’s engineers decided from the start to design the F-16’s airframe life to last to 8,000 hours and for 9-g maneuvers on full internal fuel. This proved advantageous when the aircraft’s mission was changed from solely air-to-air combat to multi-role operations. Changes over time in actual versus planned operational usage and continued weight growth due to the addition of further systems have required several structural strengthening programs.

Aerodynamic studies in the early 1960s demonstrated that the phenomenon known as “vortex lift” could be beneficially harnessed by the adoption of highly swept wing configurations to reach higher angles of attack through use of the strong leading edge vortex flow off a slender lifting surface. Since the F-16 was being optimized for high agility in air combat, GD’s designers chose a slender cropped-delta wing with a leading edge sweep of 40° and a straight trailing edge. To improve its ability to perform in a wide range of maneuvers, a variable-camber wing with a NACA 64A-204 airfoil was selected. The camber is adjusted through the use of leading-edge and trailing edge flaperons linked to a digital flight control system (FCS) that automatically adjusts them throughout the flight envelope. The F-16 has a moderate wing loading, which is lower when fuselage lift is considered.

This vortex lift effect can be increased by the addition of an extension of the leading edge of the wing at its root, the juncture with the fuselage, known as a strake. The strakes act as a sort of additional slender, elongated, short-span, triangular wing running from the actual wing root to a point further forward on the fuselage. Blended fillet-like into the fuselage, including along with the wing root, the strake generates a high-speed vortex that remains attached to the top of the wing as the angle of attack increases, thereby generating additional lift. This allows the aircraft to achieve angles of attack beyond the point at which it would normally stall. The use of strakes also allows a smaller, lower-aspect-ratio wing, which in turn increases roll rates and directional stability, while decreasing aircraft weight. The resulting deeper wingroots also increase structural strength and rigidity, reduce structural weight, and increase internal fuel volume.

The F-16 was the first production fighter aircraft intentionally designed to be slightly aerodynamically unstable. This technique, called “relaxed static stability” (RSS), was incorporated to further enhance the aircraft’s maneuver performance. Most aircraft are designed with positive static stability, which induces an aircraft to return to its original attitude following a disturbance. This hampers maneuverability, as the tendency to remain in its current attitude opposes the pilot’s effort to maneuver; on the other hand, an aircraft with negative static stability will, in the absence of control input, readily deviate from level and controlled flight. Therefore, an aircraft with negative static stability will be more maneuverable than one that is positively stable. When supersonic, a negatively stable aircraft actually exhibits a more positive-trending (and in the F-16’s case, a net positive) static stability due to aerodynamic forces shifting aft between subsonic and supersonic flight. At subsonic speeds the fighter is constantly on the verge of going out of control.

To counter this tendency to depart from controlled flight—and avoid the need for constant minute trimming inputs by the pilot, the F-16 has a quadruplex (four-channel) fly-by-wire (FBW) flight control system (FLCS). The flight control computer (FLCC), which is the key component of the FLCS, accepts the pilot’s input from the stick and rudder controls, and manipulates the control surfaces in such a way as to produce the desired result without inducing a loss of control. The FLCC also takes thousands of measurements per second of the aircraft’s attitude, and automatically makes corrections to counter deviations from the flight path that were not input by the pilot; coordinated turn is also obtained in such a way that it updates itself by thousands of instructions and produces the required control deflection that comes from dynamics of F-16, thereby allowing for stable flight. This has led to a common aphorism among F-16 pilots: “You don’t fly an F-16; it flies you.”

The FLCC further incorporates a series of limiters that govern movement in the three main axes based on the jet’s current attitude, airspeed and angle of attack, and prevent movement of the control surfaces that would induce an instability such as a slip or skid, or a high angle of attack inducing a stall. The limiters also act to prevent maneuvering that would place more than a 9 g load on the pilot or airframe.

Though the FLCC’s limiters work well to limit each axis of movement, it was discovered in early production flight testing that “assaulting” multiple limiters at high angles of attack and low speed can result in angles of attack far exceeding the 25-degree threshold of limiting. This is colloquially referred to as simply “departing”. Depending on the attitude of the aircraft, it may settle into a deep stall; a near-freefall at 50° to 60° AOA, either upright or inverted. In this “pocket” of very high AOA, the aircraft’s attitude is stable, but being far above stall AOA, the control surfaces do not operate effectively. Further, the pitch limiter of the jet, sensing the high AOA, “freezes” the stabilators in an extreme pitch-up or pitch-down in an attempt to recover. To recover, an override is provided that disables the pitch-limiting, which then allows the pilot to “rock” the aircraft’s nose up and down using pitch control, eventually overcoming the 50° threshold and achieving a nose-down attitude which will reduce AOA and allow a return to controlled flight.

Unlike the YF-17 which featured a FBW system with traditional hydromechanical controls serving as a backup, the F-16’s designers took the innovative step of eliminating mechanical linkages between the stick and rudder pedals and the aerodynamic control surfaces. The F-16’s sole reliance on electronics and wires to relay flight commands, instead of the usual cables and mechanical linkage controls, gained the F-16 the early moniker of “the electric jet”. The quadruplex design permits “graceful degradation” in flight control response in that the loss of one channel renders the FLCS a “triplex” system. The FLCC began as an analog system on the A/B variants, but has been supplanted by a digital computer system beginning with the F-16C/D Block 40.

The F-16 program has suffered from controls that were sensitive to static electricity or electrostatic discharge (ESD), including 70–80% of the electronics on the C/D models sensitive to ESD in the early 1980s.

The F-16A/B was originally equipped with the Westinghouse AN/APG-66 fire-control radar. Its slotted planar-array antenna was designed to be sufficiently compact to fit into the F-16’s relatively small nose. In uplook mode, the APG-66 uses a low pulse-repetition frequency (PRF) for medium- and high-altitude target detection in a low-clutter environment, and in downlook employs a medium PRF for heavy clutter environments. It has four operating frequencies within the X band, and provides four air-to-air and seven air-to-ground operating modes for combat, even at night or in bad weather. The Block 15’s APG-66(V)2 model added a new, more powerful signal processor, higher output power, improved reliability, and increased range in a clutter or jamming environments. The Mid-Life Update (MLU) program further upgrades this to the APG-66(V)2A model, which features higher speed and memory.

The AN/APG-68, an evolution of the APG-66, was introduced with the F-16C/D Block 25. The APG-68 has greater range and resolution, as well as 25 operating modes, including ground-mapping, Doppler beam-sharpening, ground moving target, sea target, and track-while-scan (TWS) for up to 10 targets. The Block 40/42’s APG-68(V)1 model added full compatibility with Lockheed Martin Low-Altitude Navigation and Targeting Infra-Red for Night (LANTIRN) pods, and a high-PRF pulse-Doppler track mode to provide continuous-wave (CW) target illumination for semi-active radar-homing (SARH) missiles like the AIM-7 Sparrow. The Block 50/52 F-16s initially received the more reliable APG-68(V)5 which has a programmable signal processor employing Very-High-Speed Integrated Circuit (VHSIC) technology. The Advanced Block 50/52 (or 50+/52+) are equipped with the APG-68(V)9 radar which has a 30% greater air-to-air detection range, and a synthetic aperture radar (SAR) mode for high-resolution mapping and target detection and recognition. In August 2004, Northrop Grumman received a contract to begin upgrading the APG-68 radars of the Block 40/42/50/52 aircraft to the (V)10 standard, which will provide the F-16 with all-weather autonomous detection and targeting for the use of Global Positioning System (GPS)-aided precision weapons. It also adds SAR mapping and terrain-following (TF) modes, as well as interleaving of all modes.

The F-16E/F is outfitted with Northrop Grumman’s AN/APG-80 Active Electronically Scanned Array (AESA) radar, making it only the third fighter to be so equipped. Northrop Grumman is continuing development upon this latest radar, to form the Scalable Agile Beam Radar (SABR). In July 2007, Raytheon announced that it was developing a new Raytheon Next Generation Radar (RANGR) based on its earlier AN/APG-79 AESA radar as an alternative candidate to Northrop Grumman’s AN/APG-68 and AN/APG-80 for the F-16.

The powerplant first selected for the single-engined F-16 was the Pratt & Whitney F100-PW-200 afterburning turbofan, a slightly modified version of the F100-PW-100 used by the F-15. Rated at 23,830 lbf (106.0 kN) thrust, it remained the standard F-16 engine through the Block 25, except for new-build Block 15s with the Operational Capability Upgrade (OCU). The OCU introduced the 23,770 lbf (105.7 kN) F100-PW-220, which was also installed on Block 32 and 42 aircraft; the main difference being a Digital Electronic Engine Control (DEEC) unit, which improved engine reliability and reduced the risk of engine stalls. Added to the F-16 production line in 1988, the “-220” also supplanted the F-15’s “-100,” increasing commonality. Many of the “-220” jet engines on Block 25 and later aircraft were upgraded from mid-1997 to the “-220E” standard, which enhanced reliability and engine maintainability; the changes allowed for a 35% reduction of unscheduled engine removals.

Development of the F100-PW-220/220E was the result of the USAF’s Alternate Fighter Engine (AFE) program (colloquially known as “the Great Engine War”), which also saw the entry of General Electric as an F-16 engine provider. Its F110-GE-100 turbofan required modification of the F-16’s inlet; the original inlet limited the GE jet’s maximum thrust to 25,735 lbf (114.5 kN), while the new Modular Common Inlet Duct allowed the F110 to achieve its maximum thrust of 28,984 lbf (128.9 kN) in afterburner. (To distinguish between aircraft equipped with these two engines and inlets, from the Block 30 series on, blocks ending in “0” (e.g., Block 30) are powered by GE, and blocks ending in “2” (e.g., Block 32) are fitted with Pratt & Whitney engines.)

Further development by these competitors under the Increased Performance Engine (IPE) effort led to the 29,588 lbf (131.6 kN) F110-GE-129 on the Block 50 and 29,160 lbf (129.4 kN) F100-PW-229 on the Block 52. F-16s began flying with these IPE engines on 22 October 1991 and 22 October 1992, respectively. Altogether, of the 1,446 F-16C/Ds ordered by the USAF, 556 were fitted with F100-series engines and 890 with F110s. The United Arab Emirates’ Block 60 is powered by the General Electric F110-GE-132 turbofan, which is rated at a maximum thrust of 32,500 lbf (144.6 kN), the highest ever developed for the F-16 aircraft.

Due to their ubiquity, F-16s have participated in numerous conflicts, most of them in the Middle East.

The F-16 is being used by the USAF active, reserve, and Air National Guard units, the USAF aerial demonstration team, the U.S. Air Force Thunderbirds, and as an adversary/aggressor aircraft by the United States Navy.

The U.S. Air Force has flown the F-16 in combat during Operation Desert Storm in 1991, and in the Balkans later in the 1990s. F-16s have patrolled the no fly zones in Iraq during Northern Watch and Southern Watch. They have served during the wars in Afghanistan and Iraq in the 2000s. Most recently, the U.S. has deployed them to enforce the no-fly zone in Libya.

The F-16 is scheduled to remain in service with the U.S. Air Force until 2025. The planned replacement is the Lockheed Martin F-35 Lightning II, which will gradually begin replacing a number of multirole aircraft among the program’s member nations.

The F-16’s first air-to-air combat success was achieved by the Israeli Air Force (IAF) over the Bekaa Valley on 28 April 1981, against a Syrian Mi-8 helicopter, which was downed with cannon fire. On 7 June 1981, eight Israeli F-16s, escorted by F-15s, executed Operation Opera, their first employment in a significant air-to-ground operation. This raid severely damaged Osirak, an Iraqi nuclear reactor under construction near Baghdad, to prevent the regime of Saddam Hussein from using the reactor for the creation of nuclear weapons.

The following year, during Operation Peace for Galilee (Lebanon War) Israeli F-16s engaged Syrian aircraft in one of the largest air battles involving jet aircraft, which began on 9 June and continued for two more days. Israeli Air Force F-16s were credited with numerous air-to-air kills during the conflict. F-16s were also used in their ground-attack role for strikes against targets in Lebanon. IAF F-16s participated in the 2006 Lebanon War and during the attacks in the Gaza strip in December 2008.

During the Soviet-Afghan war, between May 1986 and January 1989, Pakistan Air Force (PAF) F-16s shot down at least 10 intruders from Afghanistan.

The Pakistan Air Force has used its F-16s in various foreign and internal military exercises, such as the “Indus Vipers” exercise in 2008 conducted jointly with Turkey. Since May 2009, the PAF has also been using their F-16 fleet to attack militant positions and support the Pakistan Army’s operations in North-West Pakistan against the Taliban insurgency.

The Royal Netherlands Air Force, Belgian Air Force, Turkish Air Force, Royal Danish Air Force, and Royal Norwegian Air Force, and Venezuela have flown the F-16 on combat missions. A Dutch F-16AM shot down a Serbian MiG-29 during the Kosovo War in 1999. Belgian and Danish F-16s also supported operations in Kosovo.

Even with the last few years increased Public relations campaign and an unprecedented help from the authorities, people haven t quite totally bought to the tankless water heater technology. The primary culprit of course, is the sticker surprise that greets possible buyers. Even with offers of discounts along with other rewards, most are careful of the big purchase.

Today, planning tankless is a sign of keeping up with the periods and technology, of being environmentally conscious, and of being aware of the charge and savings for the purchaser.Householders think any good quality property growth company to involve these appliances in their properties. They will certainly request them in one that s discussing about easy

enjoying and worry-free homes.

Being subjected to the many advantages of switching into gas tankless water heaters with the enormous educational campaigns undertaken by both the business market and individuals focused on selecting eco-friendly or more environmentally friendly options to everyday living, many consumers have become aware that the technology is hardly new or untried. People are now more informed in regards to the popularity of tankless water heater use in Asia and europe.

Still, converting into a tankless device is not without concerns. As complex as they are, tankless water heaters are not perfect; but a lot of professionals still believe their shortcomings are a development over the conventional tank-style heating unit.

Other than the price, concerns about tankless solutions basically come down to:

Loss of hot water when there is reduced water supply. Because it sometimes transpires, water flow can fluctuate; based on the particular system, a tankless water heater needs a particular quantity of water supply for the heater to turn on.

The strange case of the cold water sandwich. Once again, it has something related to water flow fluctuation. The cold water sandwich effect is a thing that occurs with every tankless water heater. It occurs when the faucet is turned on, off, and on again; a slug of cold water ends up held in between the hot water supply.

However ,, considering the future, individuals do understand what the smarter option is. That is why real estate brokers and developers have been fast to leap on the environmentally friendly bandwagon, highlighting every possible environmentally friendly characteristic they can on their property buildings. Top among these features is the gas tankless water heater. It is quickly becoming a qualification in these brand new homes.

When consumers now encounter this choice-whether to go tankless or not-it s not only about doing the clever pick when it comes to funds. As most now are starting to understand, it is difficult to put a price tag on the future and on the environment.

With a lot of individuals more concerned about tightening their costs and saving for the upcoming, energy efficiency and working with their everyday power utilization is prime concern. That is why they generally request for the setting up of gas tankless water heaters when the time to change their previous tank-style heaters comes. All of them would like the savings,

convenience, and unrestricted hot water that only a tankless water heater can deliver.

Shrink is a part of the business no one likes to talk about. However, shrink plays a huge part in every retailer’s business. Shrink can take many forms, but here are the four most common. They are employee theft, shoplifting, vendor theft and paperwork errors.

Many small retailers only worry about shoplifting, but the other three accounts for about 2/3 of all shrink. We will discuss steps to help reduce your shrink.

Employee theft accounts for almost half of all shrink. Many business owners refuse to consider their employees could be stealing from them. Employee theft can take many forms such as taking cash/ merchandise, passing merchandise, and giving unauthorized discounts to name a few.

The key to controlling employee theft is to reduce the opportunity to steal. You should explain clearly to your employees if they are dishonest what the consequences will be. Here are a few suggestions.

1. You must keep the back door controlled. If it is unlocked, it is easy for employees to put merchandise outside. They could have friends or family pick it up. Also, the employee could hide the merchandise in the trash to recover after work.

2. You need to do regular inventories of high theft items.

3. You need to show up unannounced. This is especially true if you have many younger employees. They are much more likely to be involved with theft.

4. You should have your store be mystery shopped. This can see how your service is plus spot potential employee theft issues. It could be done by someone you know or through a company that specializes in mystery shops.

5. Make sure all employees give receipts. You could offer the customer something free such as $5, if the employee does not give a receipt. This makes it harder for an employee just to pocket the money. If your register keeps track of no sales, this could be a clue of a problem. Excessive no sales are either an education issue or a theft issue.

6. You should do unannounced cash counts. Vary the times and check the register total against what you are supposed to have. Also, see if you noticed anything unusual near the register area or inside the till. This could include employees have a paper with a bunch of numbers, coins or some other object in an unusual place, or part of the money unorganized.

7. You need to explain your policies to all employees’ especially new hires. You should mention that you trust all of your employees, but you have safeguards in place to protect the store assets. It would be a good suggestion to mention just a couple to let the employees know you are serious about protecting the store assets.

8. Employee’s bags and purses should be checked when leaving. Management should show their bags or purse to another employee.

9. You must have policies in place for ringing up of family or friends. Also, your discount policy needs to be clear to all employees. The most common theft is passing merchandise to family or friends or giving unauthorized discounts. For example, your $20 item may be sold for a $1. If you have a way employees can change the price of an item, you must have someway to at least spot check for potential problems.

10. You could have a tips hot line for employees to report potential shrink. Yes, on many occasions it would be used to report bogus claims about other employees. However, if work correctly, the valid claims could save you hundreds or even thousands of dollars.

11. Keep an eye on customers who are just hanging around employees. Also, if certain customers only seek certain employees could be a sign also.

12. You need to track your employee purchases. Very few purchases or excessive could be potential trouble spots with employee theft. If they never buy, it could be they are just taking merchandise. If they are buying a lot, where is the money coming from?

Shoplifting

1. You should greet every customer. It is great for customer service. Also, shoplifters do not want to be noticed.

2. Put high theft items where they are easier to watch.

3. Look for customers splitting up and one trying to keep you busy.

4. Keep your store neat and organized. Shoplifters like to leave empty packages in unorganized areas.

5. If the customer is watching the employees more than shopping.

6. Shoplifters like to go to blind spots. You may want to install some mirrors to make it easier to see the entire store.

7. Have signs made that shoplifters will be prosecuted to the full extent of the law. If you have the reputation of being soft on shoplifting, you will always have a major problem.

8. Look for nervous shoppers.

9. If shoppers come in your store often and seldom buy anything. Most shoplifters do buy a few items and just help themselves to others.

Vendor Theft

1. Check all orders for shortages. It is best a good employee or management be responsible for this.

2. Make vendors break down boxes before leaving the store.

3. Don’t hand a signed invoice to the vendor until they are done. This will help with the previous two suggestions.

Excessive shrink can cause your business to fail. Shrink cannot be eliminated, but it can be reduced. Following our suggestions is a good way to ensure that you take more money to the bank than your employees, shoppers or vendors.

One of the last things you want to find out is that your dog has ended up in a fight while at his Ft. Lauderdale doggy daycare. Not knowing the extent of the potential injuries can set a furious pace for your heart. Not being able to see who started it, or how your dog reacted only makes it significantly worse.

It is, therefore, important to ensure your dog is well protected and that the doggy daycare in Ft. Lauderdale of your choice is the right match for both you and your dog.

Making sure that the daycare is aware of the potential for fights among dogs and has policies in place to prevent them from happening is the first step.

• New dogs should be accompanied by their owner, not only as a way for the owner to ensure the daycare is a good fit for their dog, but that their dog is a good fit for the daycare.
• Ensuring that there is plenty of room for dogs to get away from other daycare goers is a good idea because, as with children, even the best friends need some time apart.
• There should also be down times and a maximum number of dogs per supervisor. This prevents energy levels from rising to an uncontrollable level.

Even with these precautions are taken, fights can happen. Your Ft. Lauderdale doggy daycare should have a written policy that explains what they will do in these circumstances. These policies should include:

• How are dogs separated? If the fight is more than a quick growling with no real intent behind their bites, often the dogs will need to be physically separated for them to discontinue their behavior. Does the kennel use objects to separate them, if so, what objects? If not, how are they separated? Trying to stop fights by stepping in is not only dangerous for the humans but also for the dogs as, should a hand end up bitten in the chaos, your dog now has a human bite on their record.
• When are owners contacted? Some daycares call their owners immediately after a fight regardless of the severity whereas others will only call in the case of a fight that requires medical attention. Which would you feel more comfortable with? Would you rather know that your dog is fine but had a tussle or would that cause you further stress?
• If medical attention is necessary, what level are they capable of handling themselves and do they take your dog to the vet if needed? What costs are involved for each? Many times there will be a transport fee along with the vet bill itself. It is also important to find out if they will transport to your vet or if they have their vet of choice that they send dogs to in the case of an emergency.
• What happens to the dogs involved? It is important to know if there is a no-strike policy in place that would have you looking into new arrangements for your dog or if these are taken on a case-by-case basis. It is also important to know that your dog will not be placed back into the situation that caused the fight to begin with.

By ensuring you understand the policies in place to both protect your dog from a fight as well as what happens should there be a fight, you will be able to relax a little more knowing what is going to happen in a worst-case scenario. Don’t be afraid to ask the doggy daycare in Ft. Lauderdale of your choice what their policies are and how they handle fights.
