Chris Evans B757-200 Fuel Burn Rate

Hi Chris,

I've downloaded 2 of your B752s now and both have a 0.0 and 0.1 fuel burn rate. Is there a way I can correct it?

Thank you,

Mike

HI,

I just repainted this.

What are the symptoms of this? Burn fuel too fast or not at all?

Unfortunately I don't much (as in not at all) edit things like fuel burn rates. Guess this is editable in the aircraft.cfg. I see several entries for fuel in the aircraft.cfg

What I would suggest is you backup (make a copy) your aircraft.cfg file then try looking at the fuel bits. Maybe you could look at a similar type aircraft.cfg and see what it is there? Maybe a 757-300? or even 767?

As long as you have a backup of the original (or at worst just get the file again!) you can't go far wrong.

I would be very interested in reading any feedback if you do edits.

No fuel burn at all.

Try editing the aircraft.cfg (make a backup, use notepad and do it outside the sim then add it to the aircraft)


Under [GeneralEngineData] you will find fuel_flow_scalar=**** (whatever number is there)


Try adjusting this to something like 0.54 - so you have fuel_flow_scalar=0.54

See how that is.


The actual fuel burn of a Boeing 757 is between 4 and 6 kg/km

I will give that a try, thank you!
