DA 62 AFM Airplane Description
7.14 AVIONICS
7.14.1 AUTOPILOT SYSTEM
General
The GFC 700 automatic flight control system (AFCS) is a 3 axis autopilot and flight director
system which provides the pilot with the following features: altitude preselect and altitude
hold (ALT); yaw damper; flight level change with airspeed hold (FLC); vertical speed hold
(VS); navigation tracking for VOR (NAV) and GPS (GPS); heading hold (HDG); approach
mode and go around (GA) pitch/roll guidance. The system consists of autopilot controls
on the multi-function display (MFD), servos with autopilot processing logic, flight director
processing logic in the GIAs, a control stick-mounted elevator trim switch, a control stick
mounted trim interrupt and autopilot disconnect switch, a control stick mounted CWS
(control wheel steering) switch, a power lever mounted GA (go-around) switch, and
PFD/MFD-mounted altitude preselect, heading, and course knobs.
The GFC 700 autopilot contains an electric pitch trim system which is used by the autopilot
for automatic pitch trim during autopilot operation and by the pilot for manual electric pitch
trim when the autopilot is not engaged. The manual electric pitch trim is operated by a
split switch on the pilot's control stick.
The GFC 700 autopilot and manual electric trim (MET) will not operate until the system
has satisfactorily completed a preflight test. The preflight test begins automatically with
initial power application to the autopilot (AVIONIC MASTER switch is set to the ON
position).
The following conditions will cause the autopilot to automatically disconnect:
- Electrical power failure
- Internal autopilot system failure
- AHRS malfunction
- Loss of air data computer information
