FUEL IMBALANCE
If fuel leak is suspected, accomplish the Fuel Leak Procedure
If fuel leak is not suspected, set the airplane attitude to wings level and
compare total fuel quantity indication on EICAS with fuel remaining
information indicated on FMS Fuel Management page. If FMS fuel
remaining quantity is lower than EICAS total fuel indication, disregard
FMS fuel remaining information. Monitor fuel quantities using the
EICAS indications.
If left wing presents lower level, set the crossfeed selector to LOW 1.
If right wing presents lower level, set the crossfeed selector to LOW
2.
Monitor fuel imbalance and, when the desired balance is achieved,
set the crossfeed selector to off. Monitor total fuel indication in
EICAS with FMS fuel remaining information.
NOTE: - The guidance to compare the total fuel quantity indication on
EICAS with fuel remaining information indicated on FMS Fuel
Management page is not valid when flying with one engine
inoperative. In this case only the fuel indications presented
on EICAS must be used.
- Crossfeed performance may be reduced in a high thrust
asymmetry condition with both engines operating. On those
conditions fuel imbalance above 793 lb (360 kg) may be
observed.
- Crossfeed performance is restored with any thrust reduction
below maximum continuous.
