Question

FLIGHT CONTROL UNIT: Pushing the SPD MACH selector does what?

B) Selects the flight control law
C) Activates the autothrottle system
D) Initiates the descent mode

Answer 1

Pushing the SPD MACH selector on a flight control unit adjusts the aircraft's speed or Mach number.

Step-by-step explanation:

Pushing the SPD MACH selector on a flight control unit adjusts the aircraft's speed or Mach number. This selector allows the pilot to input a desired speed or Mach number, which the flight control system will then maintain. For example, if the pilot pushes the selector to increase the speed, the autothrottle system will adjust the engine power to increase the aircraft's speed.
