Aircraft configuration files

[admin]

Hi all,

Today I discovered the manual is not complete enough to get your own aircraft up and running with the software.   The manual states you have to copy the air file and change the sim= line in the aircraft.cfg file.  Apparently this is not enough.  The [WEIGHT_AND_BALANCE] and [airplane_geometry] sections also need to be modified.  These are the effective values section you need to place in your file:

Code:

[WEIGHT_AND_BALANCE]
reference_datum_position= 52.786,  0.000, 1.861
empty_weight_CG_position=-57.770,  0.000, 0.000

empty_weight=91300.000
empty_weight_roll_MOI=  1630328.70
empty_weight_pitch_MOI= 2103844.05
empty_weight_yaw_MOI=   1754301.78
empty_weight_coupled_MOI=0.00
//
station_load.0= 8500, -57.770, 0.000, 1.050
station_load.1= 1485, -57.770, 0.000, 1.050
station_load.2= 1030, -57.770, 0.000, 1.050

I want to thank Hans Hartvelt for pointing this out to me.

So there is no station_load.3? Just to make sure...

Thanks for the tip!

Hi Nax,

I think you can add more stations if you want.  I'm not so good at these config files

[NAX]

hehe... and I don't even know what these staitions are 

[AirKorvet]

Stations are Cargo Holds (departments). The B738 has 4 Cargo Stations. Two at the front cargo door (left and right of the door, number 1 and 2) and two at the aft cargo door (number 3 and 4)

Hi,

In FS stations are used to determine weight distribution and following out of that the CoG.  So you can add stations for crew, passengers, cargo, ...
That's what some programs (like topcat) do.  They set the stations based on cargo, passengers, ... selected in the application.

I have been using my reconfiged 737 for a coupple of flights the last few days and wonder about why the plane shotes off and reach OVERSPEED after just a few nm, still in climb.
Feels like Engines are way to powerful or the plane is way to light. I had fun doing some STOL takeoffs and landing in Canada Shoud just get some Tundrawheels and go bushflying.
No, but seriously. Some values makes my plane acting strange.

Have any of you other this experiance?

I had to put the original config back in. I had the opposite problem to you Nax at 102% power I could only manage 60 knots on the runway.
