FOR SIMULATION PURPOSES ONLY
To enter, bring the control column (CC) back sharply to pitch the nose just
beyond the critical angle of attack (AOA), recognised from demonstration
and from experience.
How far back the CC moves is determined by the IAS and by how rapidly the
CC is applied; the higher the IAS the less aft CC required but the faster the
movement of the CC needs to be.
Exceeding critical AOA by a large margin leads to high drag, large energy
loss and lower rotation rate.
After moving the CC back but, before the critical AOA is reached,
aggressively apply full rudder in the required direction of roll. Autorotation
commences.
If a snap roll through more than 180 degrees is required full rudder in the
direction of roll should be maintained but the CC should be moved forward
to a more neutral position as sustained rearward deflection can lead to a
high drag situation and may impose undue loading on the fuselage.
During autorotation the following control inputs accelerate the roll rate:
•
Aileron in the direction of roll.
•
Forward movement of the CC.
To stop the roll, apply full opposite rudder until the rotation stops then instantly
neutralise the CC and rudder. For a precision exit anticipate the rollout
attitude by 90 degrees when applying rudder.
The high tempo of the manoeuvre, more acute at higher entry IAS, makes it a
challenging event to master.
Building up from a lower IAS entry is the way to learn.
CAUTION
A flick entry at limiting IAS on a downward flight path risks airframe overstress.
