EMERGENCY OPERATION IN CLOUDS
EXECUTING A 180° TURN IN CLOUDS (DUAL AHRS
FAILURE)
Upon inadvertently entering the clouds, an immediate turn to reverse
course and return to VFR conditions should be made as follows:
DUAL AHRS FAILURE
1. Note the non-stabilized magnetic compass heading.
2. Set rudder trim to the neutral position.
3. Using the standby attitude indicator, initiate a 15° bank left turn.
Keep feet off rudder pedals. Maintain altitude and 15° bank
angle. Continue the turn for 60 seconds, then roll back to level
flight.
4. When the compass card becomes sufficiently stable, check the
accuracy of the turn by verifying that the compass heading
approximates the reciprocal of the original heading.
5. If necessary, adjust the heading by keeping the wings level and
using the rudder to make skidding turns (the compass will read
more accurately) to complete the course reversal.
6. Maintain altitude and airspeed by cautious application of
elevator control. Keep the roll pointer and index aligned and
steer only with rudder.
