Why is landing gear called landing gear?
Attached to a gear are many tires. The tires are used the land the aeroplane. That is why it is called landing gear.
1950's war movie where the landing gear does not deploy and the young officer in the bubble under the plane draws the landing gear on a scretch pad and the landing gear appears like a characature.?

Why is Vlo lower than Vle?
Vlo = Maximum landing gear operating speed (do not exceed this speed while the landing gear is operaing) Vle = Maximum landing gear extended speed (do not exceed this speed while the landing gear is extended) When the landing gear is fully retracted or fully extended it is locked into position and is more resistant to damage from high airspeeds. When the landing gear is in the process of extending or retracting (operating) there is no locking mechanism, and the only thing resisting the airflow is the extension/retraction mechanisms. Additionally, on some aircraft, the landing gear may swing or swivel in odd directions in order to tuck into their recesses, this can cause odd aerodynamic behavoir in the rest of the aircraft if done at high speeds. Once the landing gear is extended, it is rare that a pilot would then exceed Vlo. Most of the time the landing gear is lowered shortly before landing and the pilot is doing everything he can to slow the aircraft further. However in the event that an aircraft had to be flown a long distance with the landing gear extended (such as a ferry flight to a repair facility) the pilot would go ahead & fly Vle.
Two kinds of landing gear?
There are many different kinds of landing gear that can be categorized by their geometry and their internal design. There are fixed landing gears that do not retract. These are usually a support that is made of spring steel that has a axle for a wheel. This example is found on small Cessna aircraft. Other fixed landing gear that are attached at a pin joint and have a shock strut to absorb landing loads. Helicopters are good examples as many have a fixed landing gear. The simplest landing gear shock strut is designed to stroke and absorb energy and it has an axle for either 1 or 2 wheels. These usually rotate on a trunnion at the top of the gear to allow retraction by pivoting of the entire gear. A drag brace locks it down into position. Larger gear have a bogie beam or pivot beam that have multiple wheels, either 4 or 6. The bogie beam attaches to the shock strut and is allowed to pivot during landing and taxi. It will have an actuator or locking mechanism to hold the bogie beam in proper position to allow it to retract in to the wheel well. Internal Design The simplest design is the lower half of the strut(called the Piston) is designed to stroke into the upper half (Outer Cylinder). As it does, the piston forces the fluid through an narrow opening (orifice) that restricts the movement and allows the gear to absorb energy. Many Nose landing gears are of this simple design. Other gear designs will allow the Piston to stroke to a point where it contacts a 2nd Stage. This 2nd stage will have higher pressure or an enclosed volume of air that acts as a final cushion to stop the gear. Some gears have a 2nd Chamber at the top of the gear that has its own piston and orifice. As the Piston strokes, the internal pressures build up and push against the 2nd Stage and it begins to stroke and also resist the forces. This example is found in the DC10 or MD11 Main landing gear.
How are tests conducted on landing gears?
In airlines and Air Forces, the aircraft is jacked up and the landing gear is cycled many times to test.

Where is landing gear actuator located in aircraft?
On the Landing gear
What is the landing gear on a helicopter called?
It is just called 'landing gear'
Types of landing gear?
1-tricycle gear 2-conventional gear 3-unconventional gear 4-tail wheel landing gear
What are the possible faults encountered during landing an airplan phase and how to resolve them?
the left landing gear could break, in which case, scooch to the left
How many landing gear must deploy to land?
All of the landing gear on the particular aircraft.
How big are the wheels on a Boeing 767?
A Boeing 767 aircraft has a total of 10 wheels. Two on the front landing gear, 4 on each of the two main landing gear.
What is a belly landing?
A belly landing is a landing of an aircraft without the landing gear being deployed.
What is belly landing?
A belly landing is a landing of an aircraft without the landing gear being deployed.
When does a plane deploy its landing gear?
The plane's landing gear is deployed as the plane is descending and nearing the runway.
What of the speed of a landing gear wheel during landing?
Most wheels are not "spun up" prior to landing, and go from zero rpm to that of the plane's touchdown speed almost immediately upon contact with the ground.
