APPENDIX 1
PRESSURE DEFUELING
Pressure defueling of the fuel tanks is accomplished through the fuel shutoff valves
and single point adapter. Pressure defueling is identical to suction defueling, except
that primary defueling flow is provided by the AC boost pumps or DC auxiliary pump
in each feed tank.
NOTE
AC or DC electrical power is required to operate the airplane
pumps for this procedure.
Direct pressure defueling of the wing tank is accomplished using the AC boost pumps
or DC auxiliary pump in each feed tank.
Direct pressure defueling of the center tank is not possible. Center tank fuel may
however be transferred to the wing tanks using the center tank transfer pumps. From
there, it may then be defueled via the wing tank.
LATER VERSION RDCP REFUEL/DEFUEL PROCEDURES
Differences in Later Refuel/Defuel Panel are as follows:
• The MODE SELECTOR switch is now rotary
• The START/STOP switch now includes the SOV test function
• The master ON/OFF switch is part of the mode selector switch
