INADVERTENT FLIGHT INTO ICING CONDITIONS
(Continued)
STATIC SOURCE BLOCKED
If erroneous instrument readings are suspected due to water, ice or
other foreign matter in the pressure lines going to the left flight panel's
external static pressure source, the alternate static source valve should
be pulled full on. A chart in Section 5 provides a correction which may
be applied to the indicated airspeeds and altitudes resulting from
inaccuracies in the alternate static source pressures.
NOTE
The altitude hold mode of the autopilot should be
disengaged before actuating the alternate static source
valve.
SPINS
Intentional spins are prohibited in this airplane. Should an inadvertent
spin occur, the following recovery technique may be used.
1.
RETARD POWER LEVER TO IDLE POSITION.
2.
PLACE AILERONS IN NEUTRAL POSITION.
3.
APPLY AND HOLD FULL RUDDER OPPOSITE TO THE
DIRECTION OF ROTATION.
4.
IMMEDIATELY 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 needle of the turn and bank
indicator may be referred to for this information.
