The landing gear are the black things under an airplane that normal people call wheels. They let the plane roll to a stop without having to make a belly landing and damage the rest of the plane. In maintenance, it is important because of its critical function and the high stresses exerted on the landing gear.
Because takeoffs are optional, landings are mandatory.
On the Landing gear
All of the landing gear on the particular aircraft.
A belly landing is a landing of an aircraft without the landing gear being deployed.
A belly landing is a landing of an aircraft without the landing gear being deployed.
Prior to the LANDING of the aircraft to which it is attached.
The wheels along with the system is called Landing Gear. The Landing Gear can be retracted soon after take-off. Stationary landing gears slow the aircraft down.

When the landing gear retracts, it is very important for aerodynamics that they retract into the body of the aircraft as much as possible. However, placement of the landing gear depends ultimately on factors such as the aircraft's center of gravity, its weight, its possible fuel load and much more, there may not be a good locaction in the aircraft for the wheels to rectract fully without some kind of articulation. As a result, aircraft designers often must come up with some pretty interesting solutions to enable to landing gear to be retracted fully into a space that is otherwise unused in the aircraft. Often in order for the landing gear to retract into its well, the wheel trucks may have to be rotated or pivoted. Large aircraft in particular often have multiple wheels for each of the landing gear. It is particularly difficult to design a retraction system for these as the wheel trucks may be very large and ungainly. Some large aircraft have the ability to pivot the landing gear to one direction or another for landing. This is done to increase the aircraft's capacity to land in cross-winds. In a strong cross-wind the aircraft may not be able to land gracefully pointed straight down the runway, and so the landing gear may be off-set one direction or another to allow the aircraft to land with a slight crab-angle.
Aircraft configuration can mean either the state of the flaps and landing gear or the layout of the cabin.

Retractable wheels on aircraft are often called "landing gear", and some of the engine designs used in aircraft can contain a gear box. But gears as they look like in cars aren't used in aircraft.
