MODEL 172N NORMAL PROCEDURES
with the spin until the spin recovery is initiated. An inadvertent relaxation
of either of these controls could result in the development of a nose-down
spiral.
For the purpose of training in spins and spin recoveries, a 1 or 2 turn
spin is adequate and should be used. Up to 2 turns, the spin will progress
to
a fairly rapid rate of rotation and a steep attitude. Application of recovery
controls will produce prompt recoveries (within 1/4 turn). During ex­
tended spins of two to three turns or more, the spin will tend to change into
a spiral, particularly to the right. This will be accompanied by an increase
in airspeed and gravity loads on the airplane. If this occurs, recovery
should be accomplished quickly by leveling the wings and recovering
from the resulting dive.
Regardless of how many turns the spin is held or how it is entered, the
following recovery technique should be used:
1.
VERIFY THAT THROTTLE IS IN IDLE POSITION AND AILER ­
ONS ARE NEUTRAL.
2. APPLY AND HOLD FULL RUDDER OPPOSITE TO THE DIREC ­
TION OF ROTATION.
3. JUST AFTER THE RUDDER REACHES THE STOP, MOVE THE
CONTROL WHEEL BRISKLY FORWARD FAR ENOUGH TO
BREAK THE STALL.
4. HOLD THESE CONTROL INPUTS UNTIL ROTATION STOPS.
5. 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.
Variations in basic airplane rigging or in weight and balance due to
installed equipment or right seat occupancy can cause differences in
behavior, particularly in extended spins. These differences are normal and
will result in variations in the spin characteristics and in the spiraling
tendencies for spins of more than 2 turns. However, the recovery technique
should always be used and will result in the most expeditious recovery
from any spin.
Intentional spins with flaps extended are prohibited, since the high
speeds which may occur during recovery are potentially damaging
to
the
flap/wing structure.
