NOTE.It is particularly important on these aircraft to clear the engine before take-off.
------------------------------------------
TAKE-OFF
[ ] (i) Whenever possible open the throttle slowly up to
+7 Ib./sq. in. boost only. This is imporant because if much power is used tyre wear is severe.
+- 12 lb./sq. in. boost may be used at heavy load, and should in any case be used on becoming
airborne to minirnise the possibility of Iead fouling of the sparking plugs, but +7 lb./sq. in. boost is
sufficient for a normal take-off
[ ] (ii) After raising the undercarriage, see that the red indicator lightUPcomes on and that the
tailwheel light goes out. it may be necessary to hold the selector lever hard forward against the
quadrant until the light does come on. Failure of the main wheels to lock up will spoil the airflow
through the radiators and will result in excessive temperatures.
[ ] (iii) If fitted, move the override lever smoothly back to AUTOMATIC when comfortably airborne.
[ ] (iv) Unless operating in sandy or dust laden conditions, set the carburettor air intake filter control to
NORMAL INTAKE at 1,000 ft.
-------------------------------------------
CLIMBING
The recommended climbing speed from sea level to 22,000 ft. is 180 m.p.h. (155 knots) I.A.S.
[ ] With the supercharger switch (WEP button +) at AUTO high gear is engaged automatically when the aircraft
reaches a height of about 13,000 ft. This is the optimum height for the gear change if full combat
power is being used, but if normal climbing power (2,600 r.p.m. +9 lb./sq. in. boost) is being used, the
maximum rate of climb is obtained by delaying the gear change until the boost in low gear bas fallen to
+5 lb.fsq. in.
This is achieved by leaving the supercharger switch at MS until the boost has fallen to this figure.
[ ] Use of the air intake filter reduces the full throttle height considerably.
---------------------------------------------
AEROBATICS
[ ] The following speeds in m.p.h. (knots) LAS. are recom
mended:
Roll.. 220-25° (190-220)
Loop 320-35° (230-300)
Half roll off the top of a loop 350-400 (300-350)
Climbing roll 350-450 (300-400)
[ ] Acrobatics are not permitted when carrying any external stores (except the 30-gallon blister type
drop tank) or when there is any fuel in the rear fuselage tank.
[ ] Flick manoeuvres are prohibited.
--------------------------------------------
CHECK LIST BEFORE LANDING
[ ] Reduce speed to 160 m.p.h. (140 knots) I.A.S., open the sliding hood and check:
[ ] U-Undercarriage .. DOWN (check indicator)
Tailwheel.. .. Light on
[ ] P-Propeller control or override lever. Set to give 2,400 r.p.m. (fully forward on the final approach)
[ ] S-Supercharger .. Red light out
[ ] C-Carburettor air intake filter control.. FILTER IN OPERATION
[ ] F-Fuel .. Main tanks cock ON Main tanks booster pump on
[ ] FL-Flaps DOWN
[ ] Check brake pressure, (80 lb./sq. in.) and pneumatic supply pressure (220 lb./sq. in.)
NOTE.- The undercarriage operation takes considerably
longer with the engine off than with it on
-------------------------------------------
APPROACH AND LANDING
The recommended final approach speeds in m.p.h. (knots)
LA.S. are as follows:
At typical service load (8,375 1h.)
Engine assisted .. .. .. 100 (87) Flaps down 110 (96) Flaps up
Glide .. .. .. . 110(96) Flaps down 115(102) Flaps up
[ ] The initial straight approach should be made
at a speed some 20-25 m.p.h. (17-22 knots) IAS. Above these figures.
[ ] On those aircraft which have clippedwings the speeds above should be increased by 5 m.p.h. (4
knots) IAS.
[ ] On those aircraft which have large chord rudders it is recommended that the rudder trimming tab
control should be set approximately to neutral on
the final straight approach in order to reduce the heavy footload necessary if the landing is baulked.
-------------------------------------------------
MISLANDING
[ ] The aircraft will climb away easily with the undercarriage and flaps down and the use of full take-off
power is necessary.
[ ] Open the throttle steadily to give the desired boost.
NOTE: The torque effect of the Griffon engine is opposite to and more powerful than that of the Merlin
engine, and is of opposite sign
[ ] Raise the undercarriage immediately.
[ ] With the flaps down climb at about 160 m.p.h. (140 knots) IAS.
[ ] Raise the flaps at 300 ft. and retrim.
[ ] On aircraft which have large chord rudders the footload necessary In the event of a mislanding will be very great if the rudder trimming tab is not pre-set during the final approach
