HANDLING
MANAGEMENT OF SYSTEMS
52. Management of the fuel system
(a) The L.P. and H.P. cocks and fuel master switch may be
on for starting and at all times when the engine is
running.
(b) Set the retrim switch to AUTO and the override switch
to NORMAL, to ensure all fuel is fed automatically and
in the correct sequence, the belly tank (when fitted) being
used first.
(c) For take-off, with the belly tank fitted, set the override
switch to TAKEOFF. This allows fuel to be fed from
the rear internal tank first thus ensuring that the C.G.
remains within limits for the whole trip. Once
comfortably airborne the switch should be returned to
NORMAL.
--------------------------------------------------------------------
A.L.1 (d) If the automatic balancing system fails, and a nose or
Para. 52(d) tail heavy indication is given, trim can he restored by
(c) operating the retrim switch in the direction of the white
Page 47 indicator until it returns to black. When less than 1,000
lb. of fuel remain, any out-of-trim indications may be
safely ignored, unless the aircraft appears to be abnormally
nose- or tail-heavy. Lateral out of balance may occur due
to unequal feeding, but, unless this is due to a booster
pump failure, balance will be restored as the wing tanks
empty.
(c) If a booster pump fails, the appropriate magnetic indicator
will show white and the fuel from this tank should be
considered unusable.
