FDE question: corrected versus "normal" fuel flow

Recommended Posts

Hi,Using those different values there is quite a big difference between those readings, almost factor 6.No experience with FDE etc.I can read the differences in AFSD, example:Fuelburn 10400 (2 engines) FF(pph): 5200, CFF(pph): 29000 (cruise, 1 engine)Using FF there is still FF when engines off.Using reverse, FF decreases?Using CFF no fuel flow when off, no increase with reverse power.(for the other parameters I use CN1, CN2 and EGT)Can someone explain this and how to use them.Jan"Beatus Ille Procul Negotiis"
