Question

Which of the following is the fundamental control of a common autopilot mode?

(a) Altitude control

(b) Pitch, roll and yaw control

(c) Engine control

(d) Automated landing

I got this question by my college director while I was bunking the class.

My question comes from Autopilots, Height Control and Heading Control in division Autopilots and Flight Management Systems of Avionics

Answer 1

Correct choice is (b) Pitch, roll and yaw control

Easiest explanation: The pitch attitude control loop and the heading control loop, with its inner loop commanding the aircraft bank angle, are thus fundamental inner loops in a common autopilot control mode. They are short, fast period loops which continuously control the control surfaces of an aircraft to maintain the pilot command.
