Aircraft CFG file meanings

[Sir Puma]

Looking through the aircraft.cfg file, many things are listed with several settings after it. For example.

station_load.0= 170.000, 45.000, -4.000, 3.000
station_load.1= 170.000, 5.000, 2.000, 0.000
station_load.2= 170.000, -2.100, -2.000, 0.000
station_load.3= 170.000, -2.100, 2.000, 0.000
station_load.4= 170.000, -5.300, -2.000, 0.000
station_load.5= 170.000, -5.300, 2.000, 0.000

I've ascertained that the first number is the default weight at that location. I think the second number may be left/right position, but the others don't seem to make sense.

Is there a post or faq somewhere in the internets that lists the different settings for the aircraft.cfg file?

generally they are the X, Y, Z coordinates for the "load" area...in relation to the planes axis, its like "spacial coordinates" with in the plane type of thing as far as I can see

Hi , Have a look at this site :  http://www.scenery.org/tutorials_fs2k4_SDK.htm

download the  fs2004_sdk_aircraft_container_setup.exe (609KB) . It is a MS Word document that will explain pretty everything you asked - and more!  enjoy!

The numbers are :

(fore/aft) / (right/left) / (up/down)

[Sir Puma]

Cool, thanks. I had already downloaded that SDK but hadn't opened it yet. I'll read through it for the other settings.

yep, thanks for confirming that Brett!

Also worth mentioning that the number are true measurement.....feet.

  Design in meters, but measure in feet ...

[Sir Puma]

The SDK and FSEdit have been a big help. I've been going through the settings for my L188 and getting the settings to what the aircraft actually has, like horspower, speed, RPM and such. It's hard finding all the stats on the aircraft and engine that I need, but I'm managing. When I got the aircraft it would max it's speed at about 220 kts and overspeed at about 250 @ 25000 feet. The aircraft should be able to go 352 kts at 27000 feet with no problem and not overspeed till around 400 kts. I managed to tweak the cfg file and get it to go 327 kts at 27000 with the overspeed needle pegged at 375. As I get it above 29000 the needle comes down so it's great.

All in all it's been a fun challenge.

Also of note, these measurements are from the aircraft datum line which is typically the firewall.

While that may be true of some real life aircraft, not so on the flight sim models.

MOST flightsim modellers take the model's zero modelling point as their reference *and* empty COG point.  In some cases, the reference datum point may be an arbitrary location.

I would say that the default C172 in FS-X has the reference datum point at the firewall, but I can assure you that most of the 3rd party models I've seen (and my own) do not.

When the modeller has precise manufacturer's data, then there is that benefit to plug in actual values.

Hi Felix

All I'm saying is the units used on the conctact points in the cfg are feet, so if you change the position by one unit that is one foot.

It doesn't matter where the reference point is, the units of measurement stay the same.

As it says in the SDK on the contact point...distance in feet and I was highlighting that in case it was missed and the belief was the numbers were units that did not tie into any real measure.
