b) SPINN
I
NG
The spin is steep but normal recovery action is effective. Entry is achieved by applying full rudder in the required
direction of spin at about 32 knots (60 km/hr.) while the control column is held fully back. Loss of height occurs at
about 320 feet (100 m.) per revolution when flown dual. The rate of spin is approximately 3.5 sees. per revolutions, and
the attitude 60° to 70° nose down.
Because a speed of 60 knots (110 km/hr.) may be exceeded when spinning, especially during the recovery, it is
particularly important to ensure that the flaps are up and secured before entering a spin.
WARNING — IAS errors.
Because of interference with the airflow in the vicinity of
the static vents, especially when a "pot" pitot head is fitted, errors in the airspeed indicator system may be considerable,
both when spinning and when side-slipping
