SECTION 3
EMERGENCY PROCEDURES
CESSNA
MODEL 172R
I
At the
landing flare (round-out), the nose down
moment
resulting
from
power
reduction is
an
adverse factor and the airplane may land
on
the
nose wheel. Consequently,
at flare,
the elevator trim control
should be adjusted toward the full nose up position and the power
adjusted so that the airplane will rotate to the
horizontal
attitude for
touchdown. Close the throttle
at
touchdown.
FIRES
Although engine fires
are extremely rare in flight, the
steps of the
appropriate
checklist should be
followed if
one is encountered.
After
completion of this procedure, execute
a forced landing. Do
not
attempt to restart
the engine.
The initial indication of
an electrical
fire is
usually the odor
of
burning
insulation. The checklist for this problem should result in
elimination
of the fire.
EMERGENCY
OPERATION IN CLOUDS
(Total
Vacuum
System Failure)
If both the
vacuum
pumps
fail in flight, the directional indicator
and attitude indicator will be disabled, and the pilot will have
to
rely
on
the turn
coordinator if he inadvertently flies into clouds. If an
autopilot is installed, it
too
may be affected. Refer
to
Section 9,
Supplements, for additional details concerning autopilot operation.
The following instructions
assume
that only the electrically powered
turn
coordinator is operative, and that the pilot is not
completely
proficient in instrument flying.
EXECUTING A 180° TURN IN CLOUDS
Upon inadvertently entering
the clouds, an immediate plan should
be made to turn
back as
follows:
1
.
Note the compass heading.
2. Using the clock, initiate
a standard
rate left turn,
holding the
turn
coordinator symbolic airplane wing opposite the lower left
index mark for 60 seconds.
Then
roll
back
to
level flight by
leveling the miniature airplane.
