How do you replace the Aircraft.cfg with an updated Aircraft.cfg ? Thanks for the help.

Hi

Rename the original aircraft.cfg to aircraft.orig and then copy the new aircraft.cfg into the directory. Check the [fltsim.x] sections and compare with the old aircraft.cfg now aircraft.orig. If you added textures to the aircraft before, you have to copy paste the [fltsim.x] sections to the new file and check the numbering. Each variant needs it's own number. Sometimes also camera settings need to be transfered. Compare this therefore too and copy paste if the old cfg was better than the new in this aspect.

What is it you want to achieve?

The aircraft.cfg file contains a lot of info relevant to that specific aircraft.


for instance if you want to add a textures only file you can edit that part of the aircraft.cfg file. Or change jetways in jetliners. All depends what you want to achieve.

Make sure you back up your original file!!!

Sometimes updated aircraft.cfg contain improved behaviour. I guess he wants this. So please tell us, what aircrafts cfg you're going to replace.

Yeah, we would be interested in knowing what you're trying to do, it would help us give more precise answers.

I've done that sort of thing before, long time ago, lot's of stuff needs to be updated per the new aircraft, like contact points, lights, the UI info, I forget what else.

If you experiment, be sure to back up the original aircraft.cfg file.

You can just edit the original file rather than replace it, might be faster, but you still need to back it up first.

Note well the other posts here.

The easiest way to improve "behaviour", or flight characteristics, is by modifying the [flight_tuning] parameters. Some aircraft.cfg files do not have this section, in which case each automatically defaults to 1.0. The section can be added to any .cfg file.

The main areas of performance changes in the [flight_tuning] parameters could be aileron and pitch parameters, for ex., sometimes the ailerons are too loose, in which case lowering the aileron_effectiveness number will help, or raising the pitch_stability number will tighten up the stabilizers (Note diff between "effectiveness" and "stability").

You can experiment to find out how they work. You can make the changes directly into the .cfg file, just remember the original setting, or put "//" in front of the original line like this: //aileron_effectiveness = 1.0, then copy that line right beneath itself and make the change.

However, that's just part of the picture with performance. The .air file, for ex., panther.air, also has a lot to do with performance. These can be changed out (but not modified), but then, in the [flight.x] section at the top the "sim=" must be changed to agree with the new .air file, for ex., sim=panther, and other .cfg settings like contact points, etc., have to be set back to the aircraft's .cfg settings, and it gets to be a pain.

My advice to a novice is to just experiment with the [flight_tuning] as that should help and it can't mess anything up. Changing out .air files requires some experience and patience.
