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 a line feature and reference point ±45°
to the right of the line feature (i.e. to execute a
barrel roll to the left side).
vi. To enter barrel roll, do a wing-over onto the
selected reference point to the right of the line
feature.
vii. In the dive – check engine RPM if fixed pitch
propeller is fitted.
viii. Ease out of dive just before target speed for
the manoeuvre is attained – ensure that wings
are level with the horizon on selected reference
point.
ix. If fixed pitch propeller is fitted, apply full power
as nose rises above the horizon.
x. Simultaneously, apply aileron to the left to
produce the roll, balancing with rudder, whilst
maintaining a backward pressure on the control
column (elevators) to ensure the aeroplane
spirals round the selected line feature.
xi. To keep rate of roll constant, aileron deflection
will vary with speed – ensure that wings are
level with the horizon when inverted at the 90°
reference point.
xii. Observe engine limitations in inverted flight.
xiii. Adjust elevators to assist in maintaining a
smooth roll – avoiding negative “g”.
xiv. Continue until wings are about to become level
and then smoothly centralize the controls.
xv. Barrel roll should be completed at the same
point on the horizon and at the same target
speed, where the manoeuvre was commenced
– check with line feature.
xvi. Reduce power to that required.
xvii. Minimum height for the aeroplane to be at an
even keel 2000ft agl.
