INTRODUCTION
The fuel tanks are located in the left and right wings and supply fuel to the engines and APU. Tanks can be refueled through
a single-point adapter or manually by overwing refueling. The fuel computer controls automatic refueling, powered crossflow,
fuel transfer, measurement of fuel quantity and temperature. Fuel system data is presented on the EICAS and synoptic
pages.

FUEL TANK SYSTEM
DESCRIPTION
The Challenger 300 stores fuel in the left and right wing tanks. The tanks are sealed with a fuel resistant sealant.
The tanks provide single-point and overwing refueling capability and provisions for removing condensation from the tanks
through underwing water drains. Low drag NACA vent scoops provide static venting of the tanks. Fuel quantity and temperature
measurement probes in the tanks provide indications for the EICAS.
All fuel supplied to the engines flows through the collector tanks. The left and right collector tanks are located inside each
wing tank at the rear and inboard of the wing. Each collector tank is replenished by gravity through flapper check valves
installed on the division between the collector and the wing tanks and by a scavenge ejector when the engines are operating.
The right side backup DC fuel pump takes fuel from the right collector tank and delivers it to the APU.
