Question

The FCCs, through FCC 2, provide FPS command signals to the pitch, roll and yaw trim actuators which in turn reposition the flight controls for ________ & ________ attitude hold and also heading hold in yaw.

Answer 1

The FCCs provide command signals to trim actuators for maintaining aircraft stability; FCC 2 specifically helps in pitch and roll attitude hold and heading hold in yaw. These autopilot functions are crucial for reducing pilot workload and ensuring smooth flight operations.

Step-by-step explanation:

The FCCs, or Flight Control Computers, play a crucial role in the stability and control of an aircraft. They receive input from various sensors and systems onboard and provide output to control surfaces to maintain desired flight conditions. FCC 2 is one of these computers that specifically provides command signals to the pitch, roll, and yaw trim actuators. These actuators then adjust the position of the flight controls to achieve pitch and roll for attitude hold and also maintain a specific heading hold in yaw.

Attitude hold is an automatic flight mode where the aircraft maintains a specific pitch and roll attitude, which is the orientation of the aircraft in relation to the horizon. On the other hand, heading hold maintains the aircraft on a specific compass direction. This automation is critical for reducing pilot workload, especially during long flights or in complex flight conditions.
