The EEC recorded in its NVRAM that reduced fuel flow had been detected. Probably this would only be recorded if it was unexpectedly low. In consequence, the FMV was commanded to open more and more, up to fully open. (cf. AAIB SB 2008-03, p. 2):
...until the
air to fuel mix parameters were out of range for a correct and effective burn I'd say.
Q1: how exactly is the fuel flow measured? mass? capacitance? delta P?
Q2: would a density difference for this type of special winter fuel influence the real fuel flow metering?
