Fuel System 12?20?1 FUEL TABLE OF CONTENTS Flight Crew Operating Manual Rev 3, Apr 25, 2005 CSP 700?5000?6 Volume 2 12?00?2 Page GENERAL Fuel is contained in a wet wing box structure, which is sealed to form three main separate wing tanks (left wing, right wing and center wing). The tanks are vented to atmosphere and slightly pressurized by an air scoop located on the lower surface of each wing. A scavenge pump purges fuel from the vent lines and a climb vent, located in each main wing tank, provides ventilation when the airplane is in a nose up attitude. Each engine is supplied with fuel from its respective feed tank which contains two alternating current or AC primary pumps and one Direct Current (DC) back up boost pump. The transfer system maintains the feed tanks full during all attitudes and provides automatic transfer of fuel from the center tank to the main wing tanks. Lateral balance between left and right main tanks is controlled automatically by the Fuel Management and Quantity Gauging Computer (FMQGC) or manually through switch selections in the flight compartment. FGF1210_001 ENGINE DRIVEN PUMPS AC MOTOR PUMPS AC MOTOR PUMPS (TRANSFER) CENTER TANK MAIN WING TANK DC PUMPS (START, EMERGENCY FEED TANKS AND WING TRANSFER) (ENGINE FEED) Flight deck control is provided on the overhead panel and fuel quantity and warnings are displayed on EICAS. A single point pressure refuel/defuel adapter is provided which is connected to a manifold containing shutoff valves. Pressure refueling can be done either automatically or manually. Gravity filling is provided for each tank.
