Answer» CORRECT answer is (b) When landing tail is closer to the ground

Easiest explanation: When an aircraft lands it has to do the flare maneuver where the pilot pitches the aircraft’s NOSE up to slow down the plane. Radio altimeter measures precise distance from the ground and SINCE the tail is closer to the ground than the nose, to measure the minimum distance it is PLACED in the tail.
