Learjet 35A - Fuel Management

FUEL MANAGEMENT
For flight planning, use only TOTAL pound indication on the fuel quantity
gage.
Do not use separate tank indications for this purpose. The fuel quan-
tity indicating system is set to indicate properly in level flight.
The red LOW FUEL warning light on the glareshield annunciator panel will
illuminate when the fuel level in either wing tank is approximately 400-500
pounds.
The amber FUEL XFLO light (if installed) on the glareshield annunciator
panel
will be illuminated whenever the crossflow valve is open. The cross-
flow valve will be open during wing to wing transfer, wing to fuselage trans-
fer, or fuselage to wing transfer.
Steady illumination of any of
the amber fuel system valve lights on the fuel
control panel, except fuel jettison valve lights, indicates the corresponding
valves
are not in the position selected. Momentary illumination while the
corresponding valve is in transit after switching modes indicates proper op-
eration.
On aircraft incorporating SB 35/36-28-11, illumination of the annunciator
installed in either STANDBY
PUMP switch indicates power is applied to the
corresponding standby
fuel pump (regardless of switch position). It is normal
for the annunciators
to illuminate during starter-assisted starts, fuselage tank
ALL operations and whenever the STANDBY
PUMP switch is ON.
The fuel control panel on the pedestal contains all the necessary switches
and indicators
to fuel the aircraft and maintain proper fuel management.
