AMPLIFIED EMERGENCY
PROCEDURES
The
following paragraphs
are
presented
to
supply
additional
information for
the
purpose
of providing
the pilot
with a
more
complete understanding
of
the recommended
course
of
action
for~
an emergency
situation.
1.
An autopilot
or
autotrim malfunction occurs when there is an
uncommanded deviation in the airplane flight path or when
there is
abnormal control
wheel or
trim
wheel motion. In some
cases,
and especially for autopilot trim, there may be
little
to
no
airplane
motion,
yet
the red
PITCH
TRIM
annunciator
(airplane’s
annunciator
panel)
may
illuminate and
an
alert
tone
may
sound.
The primary
concern in
reacting
to
an
autopilot
or
autopilot
trim
malfunction,
or
to
an
automatic disconnect of the
autopilot, is in maintaining control
of
the
airplane.
Immediately
grasp
the
control
wheel and press
and
hold down the A/P
DISC/TRIM INT
switch throughout the recovery. Manipulate
the controls as required
to safely
maintain operation of the
airplane
within
all
of
its
operating
limitations.
Elevator
trim
should be used manually
as needed
to
relieve control forces.
Locate and pull the
AUTO PILOT
circuit breaker
on
the
right
hand circuit breaker panel
to
completely
disable the
autopilot
system.
2.
A
manual electric
trim
malfunction
may
be recognized by
illumination of the
red
PITCH TRIM
annunciator, accompanied
by
an alert
tone,
or by
unusual
trim
wheel motions
with
the
autopilot OFF,
without pilot actuation of the manual electric
trim
switches.
As
with
an
autopilot
malfunction, the
first
concern following
a manual electric trim
malfunction
is
maintaining
control of
the airplane.
Grasp
the control wheel
firmly and
press and hold down the A/P DISC/TRIM INT
switch. Locate
and
pull
the
AUTO PILOT
circuit breaker on
the right hand breaker panel.
