System
avionics architecture. The System Overview section provides a block diagram to support this system description.
The AFCS can be divided into these main operating functions:
•
Flight Director (FD)
— Flight director operation takes place within either GIA 63W. Flight director commands
are displayed on the PFD. The flight director provides:
– Command Bars showing pitch/roll guidance
– Vertical/lateral mode selection and processing
– Autopilot communication
•
Autopilot (AP)
— Autopilot operation occurs within the pitch, roll, yaw, and pitch trim servos. It also provides
servo monitoring and automatic flight control in response to flight director steering commands, Attitude and
Heading Reference System (AHRS) attitude and rate information, and airspeed.
•
Yaw Damper (YD
) — The yaw servo (
optional
) is self-monitoring and provides Dutch roll damping and turn
coordination in response to yaw rate, roll angle, lateral acceleration, and airspeed.
•
Manual Electric Trim (MET)
— The pitch trim adapter provides manual electric pitch trim capability when
the autopilot is not engaged and provides directional trim during climbs and descents.
