QUESTIONThe Remote Pilot study guide defines stability as the inherent quality of an aircraft to correct for conditions that may disturb its equilibrium and to:

  1. Areturn to or continue on the original flight path
  2. Brespond immediately to every one of the pilot's control inputs
  3. Cwithstand the stresses imposed by maneuvers
Show the answer and explanation

Correct answer: A. return to or continue on the original flight path

  • A — correct The guide defines stability as the inherent quality to correct for disturbances and to return to or continue on the original flight path.
  • B — incorrect Responding to the pilot's control describes controllability, not stability.
  • C — incorrect Withstanding maneuvering stresses is part of the guide's description of maneuverability, not stability.

BACKGROUND

The Remote Pilot study guide describes stability as the inherent quality of an aircraft to correct for conditions that may disturb its equilibrium and to return to or continue on the original flight path. Stability is primarily an aircraft design characteristic. The guide contrasts it with maneuverability, the quality that lets an aircraft be maneuvered easily and withstand maneuvering stresses, and controllability, the capability to respond to the pilot's control. The position of the center of gravity has a great bearing on stability.

STUDY TIP

Keep the three terms separate: stability returns the aircraft to its path, maneuverability handles maneuvering stress, controllability responds to the pilot.

KEY POINTS

  • Stability corrects disturbances and returns the aircraft to its original flight path.
  • It is primarily a design characteristic.
  • CG position strongly affects stability.
