A.L.3 Page 65 limitations, G should not be increased beyond the initial buffet stage
at speeds above 0.85M at heights below 25,000 ft.
69. Aerobatics
The following are the recommended minimum speeds, in knots, for
aerobatics until experience is gained:-
Roll (full aileron) ... ... ... 350
Loop ... ... ... ... 460
Roll off ... ... ... ... 480
Vertical roll ... ... ... ... 520
70. Spinning
(a) Intentional spinning is prohibited.
(b) The aircraft is not prone to spin off a stall, either in level or turning
flight.
(c) As a result of tests the following actions are recommended in the
event of a spin developing:-
(i) Apply full opposite rudder and ease the stick forward taking
care to ensure that the ailerons are central. If in doubt release
the handgrip and allow the feel spring to centre the ailerons.
(ii) If the undercarriage and flaps arc down they should be retracted
immediately.
(iii) Maintain full rudder until all rotation has ceased. Centralise the
controls quickly when the spin stops.
(iv) If the aircraft stops in a steep nose-down attitude, extending the
airbrakes will enable a tighter pullout to he made.
(v) If the aircraft is beyond the vertical when the spin stops, less
height will be lost if it a half rolled before pulling out, but the
ailerons must be used very gently.
(d) Flight tests with a ventral drop tank have not been made, but
evidence from model tests shows that the tank does not affect a spin
recovery and jettisoning the tank during the spin may cause damage
to the wing. The tank should not therefore be jettisoned.
Note.-1. The normal characteristics are a slow rate of spin with
considerable oscillation in pitch, the nose dropping
steeply down and rising almost to the horizon once in
each turn. Recovery action is effective at once when taken
with the nose up and within half a turn with the nose
down. A moderate force is required to apply opposite
rudder and a light force to hold the stick forward.
2. Some spins vary from Note 1 as regards recovery charac-
teristics and are as follows:-
A very light force is required to apply the opposite rudder
and a marked degree of sideslip may be felt. This is
usually followed by a sudden increase in the rate of spin
which may continue with the aircraft pointing steeply
down for a further 1 or 1½ turns before stopping.
3. Height loss will nary considerably but the average height
involved in making one turn of a spin and recovery to
level flight is about 9,000 ft.
4. It is recommended that the aircraft be abandoned if a
spin occurs below 15,000 ft. or if a spin which has
developed above this height has not been stopped by
10,000 ft. 65 -----------------------------------------------------------------------
