This set of Aircraft Maintenance Multiple Choice Questions & Answers (MCQs) focuses on “Aircraft Systems and Aviation – Autopilot-1”.
1. Autopilot system is used to control the_____ of an aircraft.
c) Landing gear
d) Air conditioning
Explanation: Autopilot system is used to control the trajectory of an aircraft. The system eliminates the need of constant hands-on control by a human operator.
2. The autopilot is often used in conjunction with the _____
c) Auto throttle
Explanation: The autopilot is often used in conjunction with the auto throttle. Auto throttle is the analogous system which controls the power delivered by the engines.
3. When was the first autopilot developed?
Explanation: The first autopilot was developed in 1912, by Sperry Corporation. The system allowed the aircraft to fly straight and level on a compass course without the pilot’s attention.
4. Not all passenger aircraft flying today have an autopilot system.
Explanation: True, smaller and older general aviation aircraft are still hand flown. Further, small airliner may also be flown without an autopilot as they are operated on short-haul flights with two pilots.
5. Autopilots in modern complex aircraft are_____ axis.
Explanation: Autopilots in modern complex aircraft are three axis. Three axis control is essential to control the roll, pitch and yaw of an aircraft. The system maybe further divided into different phases.
6. What is the full form of CWS?
a) Control Wheel Steering
b) Control Wheel Stoppage
c) Crank Wheel Steering
d) Cross Wheel Steering
Explanation: CWS refers to Control Wheel Steering. It is an option that lies midway between fully automated flight and manual flying. It is still used as a function on many aircraft today.
7. Autopilot on airplanes maybe colloquially referred to as _____
Explanation: Autopilot on airplanes maybe colloquially referred to as George. The system allows to focus on broader aspects of operations, thereby reducing their workload.
8. A two axis autopilot controls an aircraft in the pitch and yaw axis.
Explanation: False, a two axis autopilot control system is able to control the aircraft in the pitch and the roll axis. The system receives inputs from radio navigation systems present onboard the aircraft.
9. A single axis autopilot controls an aircraft in the _____ axis only.
Explanation: A single axis autopilot controls an aircraft in the roll axis only. In general, there are three levels of control in autopilots for smaller aircraft.
10. An autopilot controlled landing on a runway is known as a _____ landing.
Explanation: A landing which is under the control of autopilot systems may be referred to as a CAT IIIB landing. All major airports around the world are capable of providing support for such landing procedures.
