g. Single-Point Pressure Refueling.
Using ser-
vice instructions printed on the inside panel of the refuel
panel access door (fig 2-45), perform pressure refueling
precheck. Remove adapter cap, and using an Army sup-
plied SPA nozzle, fill fuel cells with correct fuel to the re-
quired level (table 2-7). When single-point pressure re-
fueling do not exceed 50 psi fuel flow. With the SPA
nozzle, fuel flow at 50 psi is at least 100 gallons per min-
ute.
WARNING
The pilot and CPG shall perform their
armament safety check prior to enter-
ing the forward area refueling point
(FARP).
Radio transmissions shall be limited
to EMERGENCIES ONLY until refuel-
ing has been completed.
