SECTION 3
EMERGENCY PROCEDURES
Although engine fires are extremely rare in flight, the steps of the
a ppropriate checklist should be followed if one is encountered. After
completion of this procedure, execute a forced landing as soon as possi-
ble. 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
(Vacuum System Failure)
In the event of a vacuum system failure during flight in marginal
weather, the directional indicator and attitude indicator will be dis-
abled, and the pilot will have to rely on the turn coordinator or the turn
and bank indicator if he inadvertently flies into clouds . The following
instructions assume that only the electrically-powered turn coordinator
or the turn and bank indicator 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 time of the minute hand and observe the position of the
sweep second hand on the clock.
(2) When the sweep second hand indicates the nearest half-minute,
initiate a standard rate left turn, holding the turn coordinator sym-
bolic airplane wing opposite the lower left index mark for 60 se-
conds. Then roll back to level flight by leveling the miniature air-
plane.
(3) Check accuracy of the turn by observing the compass heading
which should be the reciprocal of the original heading .
(4)
If necessary, adjust heading primarily with skidding motions
rather than rolling motions so that the compass will read more
accurately.
(5) Maintain altitude and airspeed by cautious application of eleva-
tor control. Avoid overco ntrolling by keeping the hands off the
control wheel as much as possible and steering only with rudder.
EMERGENCY DESCENT THROUGH CLOUDS
If conditions preclude reestablishment of VFR flight by a 180° turn,
