CESSNA AIRCRAFT COMPANY FOR TRAINING USE ONLY
MODEL 152 3-12
6. Apply carburetor heat.
7. Clear engine occasionally, but avoid using enough power to disturb the trimmed glide.
8. Upon breaking out of clouds, resume normal cruising flight.
FLIGHT IN ICING CONDITIONS
Flight into icing conditions is prohibited. 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.
SPINS
Should an inadvertent spin occur, the following recovery procedure should be used:
1. PLACE AILERONS IN NEUTRAL POSITION.
2. RETARD THROTTLE TO IDLE POSITION.
3. APPLY AND HOLD FULL RUDDER OPPOSITE TO THE DIRECTION OF ROTATION.
4. JUST AFTER THE RUDDER REACHES THE STOP, MOVE THE CONTROL WHEEL BRISKLY FORWARD
FAR ENOUGH TO BREAK THE STALL. Full down elevator may be required at aft center of gravity
loadings to assure optimum recoveries.
5. HOLD THESE CONTROL INPUTS UNTIL ROTATION STOPS. Premature relaxation of the control
inputs may extend the recovery.
6. AS ROTATION STOPS, NEUTRALIZE RUDDER, AND MAKE A SMOOTH RECOVERY FROM THE
RESULTING DIVE.
NOTE
If disorientation precludes a visual determination of the direction of
rotation, the symbolic airplane in the turn coordinator may be referred
to for this information.
For additional information on spins and spin recovery, see the discussion under SPINS in Normal
Procedures (Section 4).
ROUGH ENGINE OPERATION OR LOSS OF POWER
CARBURETOR ICING
A gradual loss of RPM and eventual engine roughness may result from the formation of carburetor ice.
To clear the ice, apply full throttle and pull the carburetor heat knob full out until the engine runs
smoothly; then remove carburetor heat and readjust the throttle. If conditions require the continued
use of carburetor heat in cruise flight, use the minimum amount of heat necessary to prevent ice from
forming and lean the mixture slightly for smoothest engine operation.
