PART I - DESCRIPTIVE
FUEL SYSTEM
2. Tanks
(a) Fuel is carried in four flexible bag-type tanks in the centre
fuselage and in four inter-connected tanks in the forward
edge of each mainplane. Provision is made for carrying
2 or 4 x 100 gallon pylon drop tanks, which may be
jettisoned electrically. (See para 54.)
(b) Each front tank contains a two-speed electrically-driven
immersed booster-pump and a 3½ gallon capacity fuel
recuperator, the contents of which are used when booster-
pump pressure falls, e.g. during inverted flight. The total
contents of the recuperators are sufficient to provide for
15 seconds flight in such circumstances at full power at
sea level. Two amber warning lights (48), labelled FUEL
LEVEL 650 LB., on the left side of the GGS are operated
by float switches in the front tanks; the lights should
come on when the fuel level drops to approximately
650 lb. (each side). Variations of up to 50 lb. either side
of this figure can be expected.
