MSFS B787-100 fuel burn

Post by MikeC » Fri Oct 08, 2021 5:18 pm

If you have used the 787-100 in MSFS then you will be aware that the fuel burn rate is ridiculously low. There is a fix for this, just search for B78XH mod on the internet. This mod brings the fuel burn rate up to a more realistic level by increasing the fuel_flow_scalar from 0.8 to 1.1336 (the engine.cfg file that appears not to exist in the asbo model is now visible).
The mod also introduces a method of inputting simbrief flight plans directly into the FMC.

Hope this is of interest.

You must have a newer version than me, I just checked my MSFS install and I can't find an engines.cfg file in Official\OneStore\asobo-aircraft-b787-10\SimObjects\Airplanes\Asobo_B787_10, am I missing something?

From what I have seen reviewing flights, 1.1336 may still be too low.

for the 787-9, not sure how that would translate to a "100" or are you referring to the 787-10?

Real world ballpark specs for the 797-9 - but be advised fuel consumption varies with altitude, airspeed and payload.
9500-9700 lbs per hour
(4309-4400 kg per hour)

I would assume with the 10 being another fuselage section longer it would burn a bit more but not significantly.

These numbers reflect "normal operations", not they way some FSA gamers fly at full payload, full max range and max cruise speeds (or more).

My mistake - it is the 787-10.

Joe - The B78XH mod instals into the Community folder and the engine.cfg file is part of that mod. I would guess that if Asbo ever apply their own fix to the problem then that might be hidden by this mod.

I agree that the figure of 1.1336 is still too low. With the mod installed I burnt 23000 kg on a 1950m flight against the FSA expected 30000kg. But that was better than the 10000kg on an similar earlier flight that got reviewed.
