PART IV-HANDLING
63. Take-off
(a) Align the aircraft and nose wheel, then open the throttle
smoothly and fully. Check :-
R.p.m. 10,600 Max. Perm. for T/O.
J.p.t. Below 710°C.
Fire warning light Out.
(b) Keep straight initially by the use of gentle braking until
the rudders become effective at 50-55 knots.
(c) Raise the nose wheel at 80-85 knots, maintain this
attitude and fly the aircraft off at 110-115 knots at
typical service load. At maximum all-up weight raise
the nose wheel at 105-110 knots, the aircraft then becomes
airborne at 120-125 knots.
(d) When safely airborne
Brake wheels.
Retract undercarriage.
Flaps UP.
Check undercarriage red lights out before 175 knots.
(e) When wing drop tanks are carried, if the undercarriage is
not retracted before a speed of 130 knots is reached, the
airflow will prevent the undercarriage doors from closing.
For this reason 30° of flaps is recommended to reduce
acceleration. If the indicator shows that the under-
carriage is not fully retracted, yawing the aircraft at about
140 knots should enable it to lock up. Where this is
unsuccessful select undercarriage down and climb to a
safe height, then reduce speed as far as is practicable and
reselect undercarriage up.
(f) At a safe height
FPI switch OFF (at full throttle).
(if used for take-off)
R/T Airborne call.
Change frequency as re-
quired.
Check call.
Pressurisation ON.
