SECTION 3
EMERGENCY PROCEDURES
CESSNA
MODEL 172R (180 HP)
At flare out, the nose down moment resulting from power
reduction is an adverse factor and the airplane may hit on the nose
wheel. Consequently, at flare out, 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.
