notice the huge difference between the service ceilings ???

The ranges supplies in the specs are considerably more than the practical range with the FSX sim

?? ?? ??

Is there a way to tweak the fuel consumption in the config file?

Thanks

Wow !
That is a very good portal in MSDN. I never new that existed.
Thanks RadarMan

Give me time to explore

Let us know what you do that helps.
Good luck!

Yes! I found the appropriate setting and changed it. It works! That MSDN link was very handy. Thanks

[GeneralEngineData]
engine_type = 5 //0=Piston, 1=Jet, 2=None, . . .
Engine.0 = -28.4, -13.3, 2.7 //(feet) longitudinal, later . .
Engine.1 = -28.4, 13.3, 2.7 //(feet) longitudinal, latera . .
fuel_flow_scalar = 1.1 //Scalar for fuel flow eff . .
min_throttle_limit = -0.25 //Minimum percent throttl . .

I change fuel_flow_scalar = 0.7

and it seems to have given the Dash about a 950 Nm practical range. That's fantastic.

At one stage I was very frustrated because, even though I was an Administrator, I could not change the
SimObjects\Aircraft\<dash 8>\aircraft.cfg
file, and I had set that folder's properties to Read/Write.
After some time I realised that I needed to rightmouse click on the [NotePad] icon and choose [Run as Administrator] . . . . . then I was able to save as expected.

Glad that you were able to use something from that page.
Happy flying!
