CESSNA SECTION 3
MODEL T182T NAV III EMERGENCY PROCEDURES
GFC 700 AFCS
U.S.
EMERGENCY OPERATION IN CLOUDS (Continued)
RECOVERY FROM SPIRAL DIVE IN THE CLOUDS (AHRS
FAILED)
AHRS FAILURE
If a spiral is entered while in the clouds, continue as follows:
1. Retard throttle to idle position.
2. Remove feet from rudder pedals.
3. Stop turn by carefully leveling the wings using aileron control to
align the roll index and roll pointer of the standby attitude
indicator.
4. Cautiously apply elevator back pressure to slowly reduce the
airspeed to 80 KIAS.
5. Adjust the elevator trim control to maintain an 80 KIAS glide.
6. Set rudder trim to neutral position.
7. Use aileron control to maintain wings level (keep roll pointer and
index aligned) and constant heading.
8. Resume EMERGENCY DESCENT THROUGH THE CLOUDS
procedure.
9. Upon breaking out of clouds, resume normal cruising flight.
INADVERTENT FLIGHT INTO ICING CONDITIONS
Flight into icing conditions is prohibited and extremely dangerous. An
inadvertent encounter with these conditions can be resolved using the
checklist procedures. The best action is to turn back or change altitude
to escape icing conditions. Set the PITOT HEAT and PROP HEAT
switches to the ON position until safely out of icing conditions.
During these encounters, an unexplained loss of manifold pressure
could be caused by ice blocking the air intake filter or in extremely rare
instances ice completely blocking the fuel injection air reference tubes.
In either case, the throttle should be positioned to hold manifold
pressure (in some instances, the throttle may need to be retarded for
maximum power). Adjust mixture as necessary for any change in
power settings.
