Final answer:
Flight control modules and various actuator control units are essential in controlling an aircraft's flight surfaces. These components play a critical role in ensuring safe and efficient control of an aircraft's flight.
Step-by-step explanation:
Flight Control Modules (FCM)
are used to control the flight surfaces of an aircraft such as the flaps, slats, and spoilers.
Primary Actuator Control Units (P-ACE)
are responsible for controlling the primary actuators, which are used to move the flight surfaces.
Slat/Flap Actuator Control Electronics (SF-ACE)
and
Horizontal Stab Actuator Control Electronics (HS-ACE)
are used to control the slats/flaps and horizontal stabilizer, respectively. The
Spoiler Actuator Control Electronics (S-ACE)
are used to control the spoilers. It is worth noting that the maintenance manual states that there should be 4 S-ACEs, rather than the given 3. These components are essential in ensuring safe and efficient control of an aircraft's flight.
