Upon 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

Then roll back to level flight by leveling the miniature airplane.
(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 ac
curately.
(5)
Maintain altitude and airspeed by cautious application of elevator
control.
Avoid overcontrolling by keeping the hands off the control
wheel and steering only with rudder.
EMERGENCY LET-DOWNS THROUGH CLOUDS.
If pOSSible, obtain radio clearance for an emergency descent through
clouds.
To guard against a spiral dive, choose an easterly or westerly
heading to minimize compass card swings due to changing blnk angles.
In addition, keep hands off the control wheel and steer a straight. course
with rudder control by monitoring the turn coordinator.
