4.13 Turning flight
In turning flight, it is necessary to co-ordinate the use of the ailerons and the rudder. At normal cruising
speeds 80 mph (70 kts) to 103 mph (90 kts) initiate the turn with aileron maintaining balance as necessary
with rudder. At bank angles exceeding 45 degrees the pitch trim force required to maintain level flight
increases noticeably. Banks exceeding 60 degrees are prohibited. In steep bank turns remember to
maintain the attitude at entry and maintain airspeed with power. Failure to maintain correct attitude can
result in a spiral dive developing. At 60 degrees of bank the stall speed is multiplied by a factor of 1.41
and you will be pulling 2g.
4.14 Slow flight, stalling and use of flaps
In cruising flight configuration with the landing flap retracted and at speeds below 62 mph (54 kt) the top
of the engine cowl will be well above the horizon. Control inputs of the aileron and rudder will be severely
dampened and the overall response of the aircraft markedly reduced. Only gentle turns should be made
of up to 20 degrees of bank ensuring the aircraft remains in balance. In slow flight if a wing drops, centrally
reduce back pressure on the stick and lower the nose. Prevent further yaw with the rudder and do not
attempt to lift the wing by aileron input.
At approximately 49 mph (43 kt) there will be a slight buffeting of the airframe. The aircraft is still
controllable. However, aileron input should not be used and the stick kept central with any tendency for
the wing to drop use opposite rudder to prevent yaw.
If stalls are entered very gently the aircraft can enter a controlled mushing descent, control can still be
maintained with rudder. (It is important not to over use rudder and potentially put the aircraft into a reverse
spin entry).
When the aircraft stalls the nose will drop. By removing back pressure the aircraft should recover. Typical
height loss in the wings-level stall is approximately 100 ft., and max. Pitch attitude change 25° below the
horizon. In turning flight stalls the typical height loss is 120 ft. At flap position 3 (full flap, 32 degrees) the
pre-stall buffet, 41 mph (36 kts), is markedly more noticeable and there is an increased tendency for the
wing to drop if balanced flight is not maintained.
4.15 Shutting down the engine
During the descent and subsequent taxiing, the engine will have cooled down enough to permit immediate
shut-down after parking. In the case of increased operating temperatures the engine should be allowed
to idle for at least 2 minutes to return to normal operating temperature before shut down.
Turn off all electrical accessories and radios before shutting down the engine.
