To review, I had trouble rigging my landing gear. Those screws were all the way IN to hit the limit switch tabs as early as possible yet I was not getting the book value turn on the hand crank after the motor stopped.
Why do aircraft have only three landing gear? This layout is most often referred to as the "tricycle" landing gear arrangement. However, there are numerous other designs that have also been used over the years, and each has its own advantages and disadvantages. Tailwheel or Taildragger Gear Though the tricycle arrangement may be most popular today, that was not always the case.
The tailwheel undercarriage dominated aircraft design for the first four decades of flight and is still widely used on many small piston-engine planes. A much smaller support is also located at the rear of the fuselage such that the plane appears to drag its tail, hence the name.
This tail unit is usually a very small wheel but could even be a skid on a very simple design. Taildragger or tailwheel landing gear What makes this form of landing gear most attractive is its simplicity.
The gear are usually relatively lightweight, and the two main gear can also be easily encased in streamlined fairings to produce low drag in flight.
Another potential advantage results from the fact that Landing gear system plane is already tilted to a large angle of attack as it rolls down the runway. This attitude helps to generate greater lift and reduce the distance needed for takeoff or landing.
This attitude is also an advantage on propeller-driven planes since it provides a large clearance between the propeller tips and the ground.
Furthermore, taildragger planes are generally easier for ground personnel to maneuver around in confined spaces like a hangar. However, the greatest liability of this landing gear layout is its handling characteristics.
If the plane is landing and one wheel touches down first, the plane has a tendency to veer off in the direction of that wheel. This behavior can cause the aircraft to turn in Landing gear system increasingly tighter "ground loop" that may eventually result in scraping a wingtip on the ground, collapsing the gear, or veering off the runway.
Landing a taildragger can be difficult since the pilot must line up his approach very carefully while making constant rudder adjustments to keep the plane on a straight path until it comes to a stop. Many taildragger designs alleviate these handling problems by fitting a tailwheel that can be locked instead of swiveling on a castor.
Locking the tailwheel helps keep the plane rolling in a straight line during landing. Stable and unstable behavior of tricycle gear vs. It is also often difficult to load or unload heavy cargos because of the steep slope of the cabin floor.
Similarly, pilots and passengers are forced to walk uphill during boarding and downhill after arrival. Many aircraft also rely on gravity to bring fuel from tanks to the engine, and some planes have been known to have difficulty starting the engine because it is uphill from the fuel supply.
Tricycle or Nosewheel Gear Now the most popular landing gear arrangement, the tricycle undercarriage includes two main gear just aft of the center of gravity and a smaller auxiliary gear near the nose. The main advantage of this layout is that it eliminates the ground loop problem of the taildragger.
This arrangement is instead a stable design because of the location of the main gear with respect to the center of gravity. As a result, a pilot has more latitude to land safely even when he is not aligned with the runway.
Tricycle or nosewheel landing gear Furthermore, the tricycle arrangement is generally less demanding on the pilot and is easier to taxi and steer.
The tricycle gear also offers much better visibility over the nose as well as a level cabin floor to ease passenger traffic and cargo handling.
A further plus is that the aircraft is at a small angle of attack so that the thrust of the engine is more parallel to the direction of travel, allowing faster acceleration during takeoff. In addition, the nosewheel makes it impossible for the plane to tip over on its nose during landing, as can sometimes happen on taildraggers.
The greatest drawback to tricycle gear is the greater weight and drag incurred by adding the large nosewheel strut. Whereas many taildraggers can afford to use non-retracting gear with minimal impact on performance, planes with nosewheels almost always require retraction mechanisms to reduce drag.
Some planes with tricycle gear also have difficulty rotating the nose up during takeoff because the main wheels are located so close to the elevator, and there may be insufficient control effectiveness. Similarly, the closeness to the rudder reduces its effectiveness in counteracting crosswinds.
Another critical factor when designing tricycle gear is to properly balance the load carried by the main gear versus the nosewheel.
Too little load on the main wheels reduces their braking effectiveness while too little on the nosewheel reduces its steering effectiveness.
Careful balancing of weight is also important to prevent the plane from tipping back on its tail while at rest on the ground. Danger of tail sitting exemplified by an improperly loaded There are many examples of aircraft with tricycle landing gear, including the F and Cessna Bicycle Gear A relatively uncommon landing gear option is the bicycle undercarriage.
Bicycle gear features two main gear along the centerline of the aircraft, one forward and one aft of the center of gravity. Preventing the plane from tilting over sideways are two small outrigger gear mounted along the wing.
Bicycle landing gear The only real advantage of bicycle gear is lower weight and drag than either the taildragger or tricycle arrangements.A Bad Travel Air Landing Gear Day.

The MD80 has a landing gear that is mechanically actuated and hydraulically operated. Normally actuated by a landing gear handle, the gear may be raised or lowered by pressure from the right hydraulic system or by pressure transferred from the left hydraulic system through the power transfer unit.
Tail wheel-type landing gear is also known as conventional gear because many early aircraft use this type of arrangement. The main gear are located forward of the center of gravity, causing the tail to require support from a third wheel assembly.
