Hi,Must be there for a long long time, but i didn't notice!My Fuel Flow gauges give a reading of 1.68 when engines off??? and 2.35 on idle.Full reverse reads 1.23.Switching to the default 747 they read (of course!!) 0.00 when off, but also no increase of FF giving reverse power.I use the same formula for my gauge:%((A:Turb eng1 fuel flow pph, pounds per hour) 1000 / 0 max 99.9 min)%!2.2f!Tested the throtlle calibration etc. no succes.So there must be something very wrong in the air.file or aircraft.cfg??Any help would be very appreciated!Jan"Beatus Ille Procul Negotiis"

For the interested,Found the clue:Forgot "Corrected" in the formula.%((A:Turb eng1 fuel flow pph, pounds per hour) 1000 / 0 max 99.9 min)%!2.2f! had to be:%((A:Turb eng1 CORRECTED ff, pounds per hour) 1000 / )%!2.2f!Jan"Beatus Ille Procul Negotiis"

Btw.Why is there such a big difference between normal and "Corrected" Turbine Engine Fuel Flow (Factor 6)?? Saw it also in AFSD.Jan"Beatus Ille Procul Negotiis"
