PART II-HANDLING
(v) Throttle back until the r.p.m. fall to 2,400 and test each
magneto in turn. The single ignition drop should not
exceed 50 r.p.m.
34. Taxying
Before taxying, check the pneumatic supply pressure
which should be 450 lb./sq. in. If lower, ensure that it has
built up since warming and running up the engine. Check
the brake pressure which should be 100 lb./sq. in. at each
wheel. If the oil cooler shutter has been closed for warm-
ing up, check with the ground crew that this has been
opened.
35. Checks before take-off
Tighten throttle friction nut
Trim : Elevator (at all
loads ... Neutral
Rudder .. Neutral
Propeller ... R.p.m. control lever fully
forward
Fuel ... ... ... Check contents
Select fuller tank
Flaps UP (TAKE-OFF position
for shortest run).
Air-intake heat control... Cold air (selector in)
(Hot air in icing conditions)
Air-intake filter control... Filtered air (slector out)
Sliding hood ... ... Closed and locked
Harness ... ... Tight and locked
Direction indicator ... Synchronised and uncaged
35. Take-off
(i) Align the aircraft with the runway, making sure
that the tail wheel is straight. Open the throttle smooth-
ly to prevent overspeeding the propeller, and keep
straight by use of rudder.
(ii) The tail comes up by itself and the aircraft may be eased
off the ground at 60 knots without flap. When using
flap the aircraft can be flown off at 50 knots.
(iii) When comnfortably airborne brake the wheels and reduce
r.p.m. to 2,400. Raise the flaps (if used) at a safe height.
