AUTOPILOT EMERGENCY PROCEDURES
12.4 AMPLIFIED EMERGENCY PROCEDURES
The following observations provide additional information for more complete understand-
ing of the recommended course(s) of action in emergency situations.
1. An autopilot or autotrim malfunction occurs when there is an uncommand-
ed deviation in the airplane flight path or when there is abnormal control
wheel or trim wheel motion. In some cases, (especially for autopilot trim),
there may be little to no airplane motion, but the PITCH TRIM annuncia-
tor (LH side of PDF) may come on.
2. The primary concern in reacting to an autopilot or autopilot trim system
malfunction, or to an automatic disconnect of the autopilot, is to keep con-
trol of the airplane. Immediately grasp the control wheel and push and
hold the A/P DISC/TRIM INT switch throughout the recovery. Manipu-
late the controls as required to safely keep the airplane within all of its
operating limitations. Elevator trim should be used manually as needed to
relieve control forces.
Switch the AP MASTER SWITCH to OFF and, when time is available af-
ter aircraft recovery, open (pull) the AUTOPILOT circuit breaker on the
lower right hand corner of the circuit breaker panel to completely disable
the autopilot system.
3. A MET (Manual Electric Trim) system malfunction (without pilot actuation
of the manual electric trim switches) may be recognized by the PITCH
TRIM annunciator coming on or by unusual trim wheel motions with the
autopilot not engaged. As with an autopilot malfunction, the first concern
following a manual electric trim system malfunction is to keep the airplane
in control. Grasp the control wheel firmly and push and hold down the
A/P DISC/TRIM INT switch. Switch the trim cut-out switch to OFF.
