EMERGENCY PROCEDURES
The
following observations provide additional information for
more
complete understand-
ing
of
the recommended course(s)
of
action
in
emergency situations.
I.
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
DISCffRIM
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
AJP
DISCffRIM
INT switch. Switch the trim cut-out switch to OFF.
