Flight Instructors Training Procedures _revised AIC_x

. Effect of momentum during recovery.
vi. DISCUSS:
With reference to applicable aeroplane type, discuss the planes of movement and application
of previously mentioned principles to slow rolls at lower and higher speeds.
vii. ADVERSE CONDITIONS AND CORRECTION
a. Aileron overbalance.
b. Aileron snatch.
c. Airframe limitations in roll (Manoeuvre Envelope) and possible consequences.
viii. FACTORS AFFECTING THE SLOW ROLL
a. Torque.
b. Slipstream.
c. Power.
3. DESCRIPTION OF AIR EXERCISE
a. APPLICABLE PROCEDURES AND CHECKLISTS
b. AEROPLANE HANDLING TECHNIQUES:-
DEMONSTRATION OBSERVATION
1. SLOW ROLL (AXIAL) i. Look out.
ii. Complete aerobatic checks – HASELL.
iii. Set climb power if C.S.U is fitted.
iv. Set trimmers for straight and level flight.
v. Select reference point ± 45° to one side.
vi. Wing-over to the reference point.
vii. Dive until the recommended speed for the
manoeuvre is achieved – check RPM if fixed
pitch propeller is fitted.
viii. Raise nose to just above the horizon (±20°),
apply full power and check climb attitude
before rolling.
ix. Smoothly but firmly apply aileron in direction of
roll and some rudder in the same direction to
compensate for adverse aileron yaw.
x. As aeroplane rolls to the vertical, apply top
rudder as necessary and whilst applying
aileron to control rate of roll, move control
column forward.
xi. Whilst inverted, use rudder to keep straight on
reference point, apply maximum aileron if
necessary and ensure control column forward
to prevent nose dropping below the horizon.
xii. Observe engine limitations in inverted flight.
xiii. As the aeroplane rolls to the vertical again,
apply top rudder to prevent “scooping” and
whilst continuing to apply full aileron, move the
control column rearwards.
xiv. When the straight and level attitude is once
again reached, set power to that required.
xv. Aim to obtain a constant rate of roll.
xvi. Minimum height for the aeroplane to be on an
