What is the primary purpose of an autopilot?

• A. Improve aircraft stability
• B. Relieve the pilot on long flights
• C. Assist during takeoff and landing
• D. To control the engine

Answer: (B)

Autopilot automatically flies the airplane along a chosen flight path, taking control of pitch, roll, yaw, and airspeed to hold the aircraft on course. The main value of this system is to reduce pilot workload during long, monotonous cruise segments, letting the crew monitor instruments, manage navigation, communicate, and plan for the next phase while the aircraft maintains altitude and speed automatically. It can improve stability as a beneficial side effect, and it may be used for some approach tasks, but it is not about engine control and is not typically used for takeoff or landing in normal operations; those phases mainly rely on pilot input or specialized systems.
