7.1 AFCS OVERVIEW
NOTE:
The approved Pilot’s Operating Handbook (POH) and FAA Approved Airplane Flight Manual (AFM)
always supersedes this Pilot’s Guide.
The GFC 700 is a digital Automatic Flight Control System (AFCS), fully integrated within the G1000 System
avionics architecture. The System Overview section provides a block diagram to support this system description.
GFC 700 AFCS functionality in the Hawker Beechcraft C90A/GT is distributed across the following Line
Replaceable Units (LRUs):
• GDU 1040A Primary Flight Displays (PFDs) (2)
• GMC 710 AFCS Control Unit
• GIA 63W Integrated Avionics Units (IAUs) (2)
• GSA 80 AFCS Servos (3)
• GSA 81 AFCS Servo (1)
• GSM 85A Servo Mounts (4)
The GFC 700 AFCS can be divided into these main operating functions:
•
Flight Director (FD)
— The Hawker Beechcraft C90A/GT has two flight directors, each operating within an
IAU and referred to as pilot-side and copilot-side. Commands for the selected flight director are displayed on
both PFDs.
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, 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 is self-monitoring and provides Dutch roll damping and turn coordination
in response to yaw rate, roll angle, lateral acceleration, and airspeed.
•
Manual Electric Pitch Trim (MEPT)
— The pitch trim servo provides manual electric pitch trim capability
when the autopilot is not engaged.
