m. (ADB) On pilot and CPG caution/warning
panels, (fig 10–56 and fig. 10–57) check that
green FUEL XFR indicators are not lighted.
If pilot and CPG indicators are still lighted, go to
paragraph 10–66D.
NOTE
The following steps transfer fuel between the forward fuel cell and the aft fuel cell.
The repairer in the pilot seat is to monitor the pilot FUEL quantity indicator vertical
displays and digital readouts, and the pilot caution/warning panel FUEL LOW
FWD and FUEL LOW AFT indicators. The assistant in the CPG seat is to monitor
the CPG selectable digital display digital readout, and the CPG caution/warning
panel FUEL LOW FWD and FUEL LOW AFT indicators. FUEL LOW FWD
indicator/quantity must be observed only when forward fuel level is decreasing.
FUEL LOW AFT indicator/quantity must be observed only when aft fuel level is
decreasing. Increasing fuel levels may provide incorrect indications. The second
assistant watches for fuel leaks during the transfer procedure. If leaks are
observed, stop transferring fuel and go to paragraph 10–12.
n. On pilot FUEL panel (fig. 10–58), set
TRANS switch to TO AFT.
o. On pilot center circuit breaker panel
(fig. 10–67.1), check that FUEL TRANS
circuit breaker stays closed.
If FUEL TRANS circuit breaker does not stay closed,
go to paragraph 10–53.
