OVERWING REFUELING - SERVICING
1. General
A. This procedure contains instructions, precautions and limits for overwing refueling.
B. Overwing refueling lets the operator add fuel to the main fuel tanks. Fuel is added through the fill ports found on top of the wings. Fuel is transferred to the center tank or auxiliary tank (if installed) as necessary.
C. Overwing refueling of the No. 1 and 2 tanks can be done if the pressure refuel equipment, or electrical power is not available. With electrical power available, the fuel quantity can be monitored from the flight compartment or the fueling panel (P15). With no electrical power available, the fuel quantity can be monitored with fuel measuring sticks.
D. If operation of boost pumps or fueling quantity indicators is necessary during overwing refueling, external power can be used for pump or indicator operation.
