QUESTIONWhich term does the Remote Pilot study guide use for an aircraft's capability to respond to the pilot's control, regardless of its stability characteristics?

  1. AManeuverability, a design characteristic
  2. BStability
  3. CControllability
Show the answer and explanation

Correct answer: C. Controllability

  • A — incorrect Maneuverability is the quality that permits easy maneuvering and withstanding of maneuvering stresses; it is governed by weight, inertia, control size and location, structure and powerplant.
  • B — incorrect Stability is the inherent quality to correct for disturbances and return to the original flight path, not the response to pilot control.
  • C — correct The guide defines controllability as the capability of an aircraft to respond to the pilot's control, especially regarding flight path and attitude, regardless of its stability characteristics.

BACKGROUND

The Remote Pilot study guide says stability significantly affects two areas: maneuverability and controllability. Maneuverability is the quality of an aircraft that permits it to be maneuvered easily and to withstand the stresses imposed by maneuvers; it is governed by weight, inertia, size and location of flight controls, structural strength and powerplant. Controllability is the capability of an aircraft to respond to the pilot's control, especially with regard to flight path and attitude. The guide notes that controllability describes the response to control application regardless of the aircraft's stability characteristics.

STUDY TIP

When a definition mentions the pilot's control input, the answer is controllability.

KEY POINTS

  • Controllability is the response to the pilot's control.
  • It applies regardless of stability characteristics.
  • Maneuverability concerns ease of maneuvering and structural stress.
