I don't know whats wrong with it.

If it is the fuel issue I can't help as there is only one AN124 model and it burns like this.

I think its a problem with the original model because flights by several users have tripped the fuel cheat formula. I did a test flight with it and did what was supposed to be a maximum range flight and only used up about half the fuel on board. I would suggest updating the fuel_flow_scalar to get more releastic results.

Well, I only can paint a/c.
I have no idea how to adjust that fuel_flow_scalar and also I don't know what the values should be.

Would you mind giving me correct values :)

Hi,

You will find a lot of developers don't bother trying to get fuel burns to the correct figure so some aircraft will use too much fuel and some will use too little. You can work out a rough fuel burn for the aircraft by working out the flight hours for the stated range of the aircraft and then dividing the fuel capacity by the flight hours. Once you have worked that out you can determine how far off your aircraft is performing and then make an adjustment to the fuel scalar to increase the amount of fuel burned to a realistic figure.

In the aircraft folder you will find an aircraft.cfg file which you can edit with notepad. This lists all the repaints etc as well as performance data and other stuff for the aircraft. The section you want is this one (as an example) :-

[GeneralEngineData] <<<<<< In this section

//0=Piston, 1=Jet, 2=None, 3=Helo-Turbine, 4=Rocket, 5=Turboprop
engine_type = 1
fuel_flow_scalar = 0.850 <<<<<< adjust this figure
engine.0 =12.000, -22.000, -0.667 // 6.000, -13.000, -0.500
engine.1 =15.000, -13.200, -0.200 // 6.000, 13.000, -0.500
engine.2 =15.000, 13.200, -0.200 // 3.000, -21.000, -0.667
engine.3 =12.000, 22.000, -0.667 // 3.000, 21.000, -0.667
min_throttle_limit=0.000000


Most aircraft will have the fuel scalar at 1.0 as a start point. Adjust the value up/down as required to get correct fuel burn. Increasing value will increase burn. After you make an adjustment save and exit and then try it. Best to change to another aircraft and back again between edits so that FS loads the amended aircraft.cfg file. At CBFS we do quite a bit of testing to make sure our fuel useage is as close to the 'book' figures as possible.

Hope that helps.

I have tested it, seems like it burns more now.
Now, the question is.
Where do we get the correct data for a certain a/c?
One more question.
I usually calculate (rough calculation) my fuel for jet a/c like this.
Depending on the type 1.5 or 2 tonnes/hour each engine. Plus 1 to 1.5 hour for taxi/hold (no divert in flynet case).
How you guys do it?
