PART 1-DESCRIPTIVE
mately 15 seconds flight under negative G conditions.
Wing drop tanks may be carried and may be jettisoned
by pulling back the WING TANKS JETTISON lever
positioned between the seats.
(b) The total internal fuel is 330 gallons made up as
follows:-
lb.
Gallons AVTAG
(7.7 lb./gall.)
Fuselage tanks ... ... 96 739
Inner wing tanks 2 X 53 gall. 106 816
Outer wing groups 2 X 64 gall. 128 985
Total internal 330 2,540
Wing drop tanks 2 X 100 gall. 200 1,540
Total (all tanks) 530 4,080
3. Fuel contents gauge
A single electrical fuel contents gauge (18) calibrated in
pounds registers the combined fuel contents of all internal
tanks when the Ground/Flight switch is at Flight, and is
mounted centrally on the instrument panel. When
SRIM 2284 is embodied the gauge is moved to the port
instrument panel. There is no fuel gauge for the drop
tanks; the main gauge will begin to show a drop in fuel
level when the drop tanks have emptied.
4. Fuel asymmetry gauges Canceled AL.2
Mod. 3598 introduces a fuel asymmetry gauge, having
three indicator needles. The two upper needles indicate
the port and starboard wing fuel contents and the bottom
needle indicates fuel asymmetry. This asymmetry needle
moves over a green sector, for "safe-to-spin"
conditions, with red sectors on either side of the green
indicating the "unsafe-to-spin" condition. The needle
moves in the direction of the heavy wing. When the
needle is in the green sector the fuel asymmetry does not
exceed 30 gallons (230 lb.) maximum.
