AUTOMATIC FLIGHT CONTROL SYSTEM
Sep 13/2004 Flight Crew Operating Manual Volume 2
REV 1 CSP 100-6 04-01-01
INTRODUCTION
The automatic flight control system (AFCS) provides a means of automatically controlling the aircraft flight path. The
AFCS reduces the flight crew workload by providing steering commands through the flight director or automatically flying
the aircraft through the autopilot. The main functions of the AFCS are:
- Dual independent flight directors
- Two axis (pitch and roll) autopilot
- Single axis yaw damper
When manually flying the airplane, dual flight directors provide steering commands to the pilots through flight director
command bars displayed on the primary flight displays. For automatic flight control, the flight director steering commands
are coupled to the autopilot.
