Static Source Blocked; Spins - Cessna TR182 1979 Pilot Operating Handbook

CESSNA
MODEL TR182
SECTION 3
EMERGENCY PROCEDURES
STATIC SOURCE BLOCKED
If erroneous readings of the static source instruments (airspeed,
altimeter and rate-of-climb) are suspected, the alternate static source
valve should be pulled on, thereby supplying static pressure to these
instruments from the cabin, Cabin pressures will vary with open ventila-
tors or windows and with airspeed, To avoid the possibility of large errors,
the windows should not be open when using the alternate static source.
NOTE
In an emergency on airplanes not equipped with an
alternate static source, cabin pressure can be supplied to
the static pressure instruments by breaking the glass in
the face of the rate-of-climb indicator.
A calibration table is provided in Section 5 to illustrate the effect of the
alternate static source on indicated airspeeds. With the windows and vents
closed the airspeed indicator may typically read as much as 4 knots faster
and the altimeter 40 feet higher in cruise. With the vents open, the speed
variation reduces to 1 knot or less. If the alternate static source must be
used for landing, the normal indicated approach speed may be used since
the indicated airspeed variations in this configuration are 3 knots or less.
SPINS
Intentional spins
IU8
prohibited in this airplane. Should an inadvert-
ent spin occur, the following recovery procedure should be used:
1. RETARD THROTTLE TO IDLE POSITION.
2. PLACE AILERONS IN NEUTRAL POSITION.
3. APPLY AND HOLD FULL RUDDER OPPOSITE TO THE DIREC-
TION OF ROTATION.
4. JUST AFTER THE RUDDER REACHES THE STOP, MOVETHE
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 recov-
ery.
6. AS ROTATION STOPS, NEUTRALIZE RUDDER, AND MAKE A
SMOOTHRECOVERY 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.
