SECTION 4
NORMAL PROCEDURES
tended s p i n s of two to three turns o r more, the spin will tend to change into
a spiral, particularly to the right. This will be accompanied by an increase
.F
i n 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 i s held o r 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 m a y be referred to for this information.
Variations i n basic airplane rigging o r in weight and balance due to
installed equipment o r right seat occupancy can cause differences in
behavior, particularly in extended spins. These differences are nonnal and
will result i n variations in the spin characteristics and in the spiraling
tendencies for s p i n s 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 m a y occur during recovery a r e potentially damaging to the
,flap/ wing structure.
LANDING
-
NORMAL LANDING
Normal landing approaches can be made with power-on or power-off
with any flap setting desired. Surface winds and air turbulence a r e usually
the primary factors in determining the most comfortable approach speeds.
