What is the primary function of landing gear?

The primary function of landing gear is to support the aircraft on the ground and absorb shock during landing and taxiing. This system is crucial for ensuring that the aircraft rests safely on the ground and is capable of withstanding the impact forces experienced during landing.

Landing gear is designed to provide stability when the aircraft is stationary or moving slowly on the ground, allowing for safe maneuvers during taxiing. Additionally, it plays a vital role in absorbing the energy generated by the aircraft as it contacts the runway during landing to minimize the forces transferred to the airframe and enhance passenger comfort.

Other functions mentioned, such as enhancing engine performance during flight, stabilizing the aircraft during turbulence, or assisting in takeoff performance, do not relate to the primary role of landing gear, which is fundamentally about ground support and shock absorption.
