Recovery From Spiral Dive In The Clouds; Inadvertent Flight Into Icing Conditions; Static Source Blocked - Cessna 182S Pilot Operating Handbook

SECTION 3
EMERGENCY PROCEDURES
RECOVERY FROM SPIRAL DIVE IN THE CLOUDS
CESSNA
MODEL 182S
If a spiral is encountered in the clouds, proceed as follows:
1. Retard throttle to idle position.
2. Stop the turn by using coordinated aileron and rudder control
to align the syrnbolic airplane in the turn coordinator with the
horizon reference li ne.
3. Cautiously apply elevator back pressure to slowly reduce the
airspeed to 80 KIAS.
4. Adjust the elevator trim control to mai ntain an 80 KIAS glide.
5. Keep hands off the control wheel, using rudder control to hold
a straight heading. Adjust rudder trim to relieve unbalanced
rudder force.
6. Clear engine occasionally, but avoid using enough power to
disturb the trimmed glide.
7. Upon breaking out of clouds , resume normal cruising flight.
INADVERTENT FLIGHT INTO ICING CONDITIONS
Flight into icing conditions is prohibited and can be extremely
dangerous. An inadvertent encounter with these conditions can best
be handled using the checklist procedures. The best procedure, of
course, is to turn back or change altitude to escape icing conditions.
STATIC SOURCE BLOCKED
If erroneous readings of the static source instruments (airspeed,
altimeter and vertical speed) are suspected, the static pressure
alternate source valve should be pulled on, thereby supplying static
pressure to these instruments from the cabin.
With the alternate static source on and the heater on and vents
closed , fly an indicated airspeed 1 to 2 knots higher than normal
during climb. During approach fly and indicated airspeed 1 to 2
knots lower than normal. Refer to the Alternate Static Source Air-
speed Calibration chart in Section 5 for additional detail. Altimeter
errors in these conditions are less than 50 feet.
