STALLING

(1) At the stall one wing usually drops sharply, often over the vertical, with flaps either up or down.
(2 ) The average stalling speeds (mph IAS) for the aircraft at various AUW (from 7,600 lbs to 9,2OO lbs. ) are:
Undercarriage and flaps UP: 80-90
Undercarriage and flaps DONW: 60-75

The speeds for individual aircraft may vary by 5 mph.


SPINNING

(1) Spinning of Mk. IID and Mk IV aircraft is prohibited at all times.

(2) On Mk IIA, B and C aircraft spinning is prohibited when carrying 90-gallon drop tanks, bombe, S. C. I. or R. P.

(3) Recovery is normal, but the loss of height involved in recovery may be very great and the following limits are to be observed:
- - -(a) Spins are not to be started below 10.000 feet.
- - -(b) Recovery is to be initiated before two turns are completed.

(4) A speed of 150 mph IAS should be attained before starting to ease out of the resultant dive.

AEROBATICS

The following speeds are recommended:
Loop : at least 280 mph IAS
Roll : 220 - 260 mph IAS
Half roll off loop : at least 300 mph IAS
Upward roll : 300 mph IAS

DIVING
(1)Speed builds up slowly in the dive and the aircraft becomes tail heavy as the speed increases.
The elevator trimming tabs should be used with care.
(2)Care should be taken not to allow the aircraft to yaw to the right, as this produces a marked nose-down pitching tendency.
(3)If fitted with bombs, S.C.I. or containers, the aircraft should be eased out of the dive gently.
If fitted with drop tanks it should not be dived.

CHECK LIST BEFORE LANDING

(1) Cheek brake pressure (100 lbs/sq.in. min.)
(2) Reduce speed to 120 mph IAS and check that cockpit hood is locked open.

U - undercarriage - DOWN ( check green lights)
P - Propeller control - Fully forward
Super charger control - MODERATE
F - Flaps – Down

APPROACH AND LANDING



Note: If carrying drop tanks, bombs, or R.P. the normal engine assisted approach should
be made at about 110 mph IAS.

Undercarriage:
The lever should have been left in neutral, but if it has been left in the UP position, be careful to disengage the thumb catch by easing the selector lever forward before trying to move it to the DOWN position, otherwise the lever may become jammed.
Return the lever to neutral as soon as the undercarriage is down.

Flaps:
If 120 mph IAS is exceeded with the flaps fully down, they will be partially raised by the airflow.
They will automatically move to the fully down position when speed is reduced sufficiently,provided that the selector lever is left at DOWN.

Landing with R.P.
Only on one wing should be made at as high a speed as possible and care must be taken to counteract dropping of the wing.

MISLANDING

(1) Raise the undercarriage immediately.
(2)Climb at about 90 mph IAS.
(3) Raise the flaps at a safe height of about 200-300 feet, at a speed of not less than 120 mph IAS.
(4) With one 500 lb. bomb stuck up open the throttle slowly and speed on the initial climb should be 110 mph IAS before raising flaps at 120 mph IAS.

AFTER LANDING

(1)Raise the flaps before taxying.
(2)To stop the engine, idle for 1 minute at 800-900 rpm, then pull the slow-running cut-out and hold it out until the engine stops.
(3)Turn OFF the fuel cock and switch OFF the ignition.
(4)Check that the hydraulic selector safety plate is covering the WHEELS UP position.
(5)Oil dilution The correct dilution period for these aircraft is:
Atmospheric temperature above -10°C: 1 minute
Atmospheric temperature below -10°C: 2 minutes
