Autopilot Malfunction
Refer to Electric Trim/Autopilot Failure procedure in the basic
Handbook. Do not reengage the autopilot until the malfunction has
been identified and corrected.
• Note •
A GPSS malfunction will most likely affect the autopilot HD
(Heading) mode, rendering it unusable. However, it may be
possible to use other autopilot lateral modes such as NAV or
approach, or the pitch (ALT) mode. Exercise caution when
examining these functions after a malfunction.
The autopilot may be disconnected by:
1. Pressing and holding the Mode Selector Knob on the Turn
Coordinator for approximately 2 seconds.
2. Pressing the A/P DISC/Trim switch on either control yoke handle.
3. Pulling the AUTOPILOT circuit breaker on the Essential Bus.
