Systems Description
Original
7–31
The engine fuel drain system provides a path for residual fuel from the combusters
and fuel control system that remains after shutdown to be directed overboard by
way of catch cans located under the baggage compartment floor.
A provision is made in the fitting at the aft left hand corner of the cell for making
a connection to an optional auxiliary fuel tank.
The pilot controls the fuel system by the Fuel System panel mounted switches.
Fuel level is sensed by a forward probe and an aft probe, and is displayed on the
IIDS. Two fuel pressure switches activate caution lights in the IIDS when the pres
sure falls below the acceptable limit.

Fuel quantity (FUEL)
is shown by segments inside the fuel tank icon,
with the
corresponding digit value in pounds, shown immediately below. The green segments
decrease vertically from the top as fuel is burned. When last green segment disap
pears, two yellow segments illuminate below to
indicate a low fuel caution (approxi
mately 45 minute reserve). When the last yellow
segment disappears, a red segment
illuminates below to indicate low fuel
(approximately 20 minute reserve). A fuel
low warning red ‘‘tick’’ mark beside the red segments is
activated when the fuel
level is between 97 and 127 lbs.
