What is one of the main purposes of the landing gear?

The primary purpose of landing gear is to provide stability on the ground. Landing gear ensures that an aircraft can safely rest on a surface without tipping or becoming unbalanced while stationary. It serves as the main support structure for the aircraft during takeoff and landing phases, absorbing impacts and providing a stable platform for ground operations such as taxiing and parking.

Additionally, landing gear is designed to withstand the forces experienced upon landing and during ground maneuvers. The stability it offers is crucial for maintaining the aircraft's integrity on the ground and for ensuring safe operations while the aircraft is not in flight. The design and structure of landing gear are fundamental elements that contribute to the overall safety and performance of the aircraft during ground operations.
