34. Flick manoeuvres.- The high-speed variety of flick-roll
or flick half-roll must ON NO ACCOUNT be done. It is liable to
cause severe strain, is clumsy and uncomfortable, and, being extremely
easy, has no training or other value of any kind. But a flick-roll
at low speed, and low r.p.m. done very gently, is a useful exercise
in timing and control at low speeds, and prevention of spin. It is
done by throttling well back, slowing down to about 140 m.p.h. A.S.I.,
and then very gently easing the stick back and, at the same time,
applying rudder. The nose will rise and yaw, and, as the control
angles are steadily increased, the aeroplane will suddenly start to
"auto-rotate", or flick. If the stick is kept back the aircraft
would then spin, but, as soon as the aeroplane approaches an even
keel (at about the moment when the wings are vertical) the stick is
put forward, and, as the flick ceases, the controls used to steady
the aeroplane until the roll is completed. If this is done too
late the aeroplane will continue to flick, until it does part of
a turn of a spin; if done too soon the flick will stop, and the
rest of the roll must be done by aileron control, in the normal way.

ON NO ACCOUNT CARRY OUT FLICK MANOEUVRES EXCEPT AT LOW SPEEDS,
but remember that low speed makes spinning more likely if the controls
are mishandled. Ample height should be allowed (see Stalling
and Spinning, paras. 17 and 19). other variations of loops, rolls
and so on may be carried out.

The word forbidden is missing and at slow speed they are allowed.
