Starting time for the fuel log is the time at the last known waypoint, found via FMC.
EICAS FUEL FLOW is in kg/hr as shown on EICAS secondary display or EICAS compact displays. This is the fuel flow indicated from the operative fuel flow sensor.
TOTAL FUEL BURN is EICAS FUEL FLOW multiplied by 2. We assume fuel flow on each engine is approximately the same.
TOTAL REMAINING FUEL starts at the last known recorded total fuel remaining data point, found via FMC. As time progresses, TOTAL FUEL REMAINING is start fuel minus TOTAL FUEL BURN.
The starting data point for this fuel log is recorded by the FMC at the last waypoint prior to FQIS failure. This is found as follows:
A. POS REPORT page
B. Line 1 displays:
Last Waypoint
Time
Altitude
C. Line 5 displays
1) POS FUEL. This is the Total Fuel Remaining at the last waypoint displayed on line 1.

MAINTENANCE (M)
NOTE: If either valve fails to move to the commanded position the EICAS status message L or R ENG CASE COOL will be displayed. The specific valve affected will be identified by the EPCS display. Messages displaying HCC/EEC will indicate a problem with the HPT and HPC case cooling air valve (high spool control valve) and messages displaying LCC/EEC will indicate a problem with the LPT case cooling air valve (low spool control valve).
