Fuel Gauges

The fuel gauges are calibrated in pounds, and may exhibit up to a 3% indication error.

Fuel Quantity Switch

When the Fuel Quantity Switch is in its spring-loaded default position, the fuel gauges will indicate the quantity of fuel in the outboard Main fuel tanks. When the switch is held down, the fuel gauges will indicate the quantity of fuel in the inboard Auxiliary fuel tanks. Adding these figures together will show the total quantity of fuel aboard.

Standby Fuel Pump Switches

Standby Fuel Pump Switches

These switches activate the standby electric low-pressure boost pump for their respective side, preventing the high-pressure pump from suction feeding in the event of a mechanical low-pressure boost pump failure.

Aux Transfer Switches

When the Aux Transfer switches are set to their default AUTO position, fuel will transfer automatically from the auxiliary tanks to the engines via a motive flow valve and jet pump. If the motive flow valve should fail to open automatically, moving the Aux Transfer switch to the OVERIDE position will command the motive flow valve to open.

No Transfer Lights

The No Transfer lights will illuminate when there is fuel in the auxiliary tanks, but inadequate fuel pressure is sensed in the transfer line.

Crossfeed Switch

When the crossfeed switch is moved to the Left or Right position, the crossfeed valve opens, and the standby boost pump on the side supplying the fuel is energized in order to "push" the fuel toward the other engine. Crossfeed is only to be used for single-engine operations. The diagram on the fuel panel illustrates the fuel flow when each position of the switch is selected.
