5.
i.
INCIPIENT SPINS FORM A CLIMBING TURN
Demonstrate incipient spins to both sides, off
climbing turns to both sides, at a reduced power
setting.
c. CONSIDERATIONS OF AIRMANSHIP AND ENGINE HANDLING
AIRMANSHIP
i Lookout.
ii HASELL checks.
iii Entry:
a. Place the aircraft in a balanced
climbing turn (15º bank) and trim for
attitude.
b. Reduce power slightly for
demonstration.
c. Allow the airspeed to bleed off.
iv Approaching the stall:
a. Slowly apply rudder in direction of
required incipient spin.
b. Simultaneously counteracting the
rolling motion caused by the rudder
input by applying opposite aileron.
c. Maintain the back pressure on the
control column to induce the stall.
d. Recognition of the stall – discuss.
NOTE: The wing with the down going aileron has the
higher angle of attack, will therefore stall first and
thereby influence the direction of the incipient spin.
v Recovery action:
SIMULTANEOUSLY
a. Apply sufficient opposite rudder to
control the yaw, thereafter centralise
the rudder.
b. Move the control column smartly
forward of neutral to unstall the wings
and centralise the ailerons.
c. Use of power – note:
To minimise the loss of height in the
recovery full power must be applied if
the recovery action is to be in time to
prevent an entry into a full spin.
NOTE: If a spin occurs, the throttle must be closed
immediately, followed by standard spin recovery.
vi. Climb away:
a. Climb power set.
b. After take-off checks.
c. Note altitude loss (if any).
i. Pre-stall checks: HASELL.
ii. Orientation problem – Verify direction of spin before commencing action.
iii. Correct us of controls.
iv. Do not open throttle in dive during the recovery.
v. Climb away after recovery – after take-off checks.
