AW139 MCDU En-route Fuel Predictions
HLCPTR - Thanks for the information, I have tried this and quite often get an error message in the scratch pad 'WIND EXCEEDED AT CRUISE ALTITUDE'.
tottigol - I have the PILOT SPD/FF selected as you say but the error is still there.
I am sure there must be something I am doing wrong as this FMS unit is used in the fixed wing world over much longer distances than helicopters are capable of. Diversions could be hundreds of miles away where fuel prediction is critical.
