WARNING
Recovery from a spin may require up to one additional turn with normal use
of controls for recovery.
WARNING
If a steady state spin is entered, holding the recommended recovery inputs of
power idle, rudder full against the spin, elevator full forward and aileron full
against the spin will produce the fastest recovery. When recovering from a
steady state spin, the aircraft may exceed the typical one turn recovery time,
and additional turns may be experienced until the aircraft recovers from the
spin.
INADVERTENT ICING
1. Detection
CHECK SURFACES (The stall strips and wing cuffs are good inspection
points for evidence of structural icing.)
2. Pitot Heat
SET TO ON
3. Course
REVERSE COURSE
4. Altitude
CHANGE (to a level where the temperature is above freezing)
5. Defroster
Divert all heated air to the defroster
6. Propeller Control
INCREASE (Higher propeller speeds will mitigate ice accumulation.)
7. Manifold Pressure
MONITOR (A drop in manifold pressure may be an indication of
induction icing; increase throttle settings as required.)
8. Heated Induction Air
SET TO ON (Operate if induction icing is evident or suspected.)
9. Alternate Static Source
(Open if static source icing is evident or suspected)
10. Flight Characteristics
ADD MARGIN OF SAFETY (An ice buildup on the wings and
other surfaces will increase stalling speeds. Add a margin to approach and landing speeds.)
11. Approach Speed
Appropriate for the amount of ice accumulation and flap setting. If there
is a heavy ice buildup on the windshield, a gentle forward slip or small S-turns may improve
forward visibility by allowing use of the side windows.
12. Landing Attitude
LIMITED FLARE (Land at a higher speed and in a flat attitude
sufficient to prevent the nose wheel from touching the ground first.)
WARNING
When flying in areas where inadvertent icing is possible, i.e., areas of visible
moisture that are not forecasted to have icing conditions, turn on the pitot
heat at least five minutes before entering the areas of visible moisture.
