3,000 pounds (1,400 kilograms), if CWT fuel quantity is greater than or equal to 50,000 pounds (22,700 kilograms) prior to engine start.

 Both CWT override/jettison pumps must be selected OFF when either CWT override/jettison fuel pump low pressure light illuminates.

 Warning: Do not reset a tripped fuel pump circuit breaker.

        Warning: Do not cycle CWT override/jettison pump switches from ON to OFF to ON with any continuous low pressure indication present.

 Note: The centre wing tank may be emptied normally during an emergency fuel jettison.

     Note: In a low fuel situation, both CWT override/jettison pumps may be selected ON and all CWT fuel may be used.

 If the main tanks are not full, the zero fuel gross weight of the aeroplane plus the weight of CWT tank fuel may exceed the maximum zero fuel gross weight by up to 7,000 pounds (3,200 kilograms) for takeoff, climb, cruise, descent, and landing, provided that the effects of balance (CG) have been considered.

 When defuelling any fuel tanks, the Fuel Pump Low Pressure indication lights must be monitored and the fuel pumps positioned to OFF at the first indication of fuel pump low pressure. Defuelling with passengers on board is prohibited.
