Flight Instructors Training Procedures _revised AIC_x

EFFECT OF CONTROLS:
SLOW FLIGHT
• Ailerons can be very ineffective.
• Adverse aileron yaw is far more
pronounced.
• Rudder effectiveness reduced:
may need greater deflection.
• Elevator less effective.
• Flying at a higher angle of attack
can produce more down wash over
the tail plane.
• Slipstream & torque effect is more
pronounced – changes in power will
have a more noticeable yawing
effect.
• Raising & lowering flap is more
critical – Do not raise flaps if the
airspeed is below Vs1. (Speed at
bottom of green arc).
MANOEUVERING MANOEUVERING CONTINUE
• From S&L flight set up slow flight at
Vs1 + 10 mph.
• Applicable procedure & checks.
• Lookout
• Note the change in nose attitude and
reduced control response.
CLIMBING from S&L V s1 + 10 mph
configuration initiate a climb at a
nominated rate and increase power to
maintain the climb rate at V s1 + 10 knots.
NOTE the control inputs required to stabilize
the climb.
TURNING from slow flight at V s1 + 10 mph
enter a medium level turn (30° AOB).
NOTE the decrease in airspeed & higher
pitch attitude to maintain a level turn and
use of power to maintain the turn.
DESCENDING from slow flight at V s1 +
10 mph nominate a rate of descent.
Reduce power and enter the descent.
Stabilize at nominated ROD. Return to
S&L V s1+ 10 knots.

To be maintained throughout.
FLIGHT EXERCISE BRIEFING
EXERCISE 10B
STALLING
*)
Repeat previous manoeuvres at V s1 + 5
mph. NB 4000’ AGL
NOTE specifically almost continuous stall
warning indications and necessity for
carefully and smoothly applied control
inputs to maneuver the aeroplane.
Repeat the previous manoeuvres at
Vs0 + 10 & V s0 + 5 mph with two notches
of flap
NOTE specifically the lower nose attitude
and absence of stall warning light.
NB: Do not raise the flaps if the airspeed
is below V s1 i.e. bottom of green arc.
CONCLUSION
• Point out the effectiveness of flap at
low airspeed reducing the possibility
of stalling.
• Stress the importance of smooth
progressive control inputs to assist
stability.
• Point out the inherent dangers of
slow flight at low height above
ground.
• Point out the impact turbulent
conditions could have, maneuvering
the A/C in slow flight.
DEFINITION: Stalling is a condition of flight where the angle between the wing and the relative airflow reaches or exceeds
the critical angle of attack causing the airflow to break away resulting in a loss of lift, loss of altitude and a
pitching moment
An aircraft can stall at any airspeed, attitude, power setting, weight, loading or configuration.
AIM: To learn how to recognize the symptoms and characteristics of the stall and then the recovery procedure
with minimum height loss.
DISCUSS: The parameters upon which the POH stall speed is derived.
