Which component provides the main support for the aircraft on the ground and during landing?

• A. Aircraft
• B. Engines
• C. Propellers
• D. Landing gear

Answer: (D)

Landing gear provides the main support for an aircraft on the ground and during touchdown. It is the system that carries most of the aircraft’s weight while taxiing and, crucially, absorbs the impact energy when the plane lands, using shock-absorbing struts and wheels to smooth the load into the runway. While engines and propellers generate thrust, they are not meant to bear the primary load on the ground and during landing, and the aircraft as a whole isn’t a single component. The landing gear is the specific structure designed to carry loads, steer, and support the aircraft when it’s not flying.
