If you have made an absolute mess of or accidently deleted any FS9 default aircraft and omitted to make backups, as most of us are liable to do, and don't want to do a re-install of the whole system there is a way of recovering these aircraft from the FS9 CD1.
Instructions:-
1. Suggest you make a new folder in My Documents and name it FS9 CD Files and then make a sub-folder in that FS9 CD Files Folder and name it Configs.
2. Insert the FS9 CD1 in the CD ROM, if the CD autostarts close the Install screen (X in the top right corner).
3. Browse in My Computer and right click on the appropriate CD ROM and select OPEN from the drop down menu.
4. Select View/Details from the top menu bar (It's easier that way)
5. Open the MSGAMES1.cab folder.
6. Scroll down until a batch of aircraft.cfg files are visible
7. Highlight all these files (Left click on the first cfg file then shift/left lick on the last cfg file.)
8. Right click on the last highlited cfg file - in the drop down menu select EXTRACT (not COPY - it won't work).
9. In the 'Select a Destination' Dialogue Box, browse to the Configs folder you made( or whatever you named it).
10. Select EXTRACT.
11. Close the CD1.
12. Browse to My Documents/FS9 CD Files/Configs (or whatever you called it) - you will note that the config files are numbered 1 up (Windows convention when files are of the same name). If you doube click on a file you will see (in Notepad)which aircraft that file is for - a bit hit or miss but if you really want your default a/c back that's what you have to do.
To give you a start I have defined which are the aircraft for the first 10 cfg files below -
1. Boe747400
2. Boe777300
3. Beech Baron 58
4. Beech king Air 350
5. Bell206 Jet Ranger
6. Cessna Sky Hawk 172SP
7. Cessna Sky Lane 182S
8. Cessna Sky Lane 182S IFR/Diff Paints
9. Cessna Caravan Amphibian
10. Cessna Grand Caravan.
That's probably the easiest part of it because you now have to recover air files, sound wav files,texture bmp files, mdl files,panel bmp files - all are in that same cabinet folder, unlike the cfg files they are all named which makes selection easier but placing these files in the correct folders could be an intricate job but you will still have a working FS9at the end of it. I shall leave that instruction for another time. Depends how much you want the default aircraft but by this time you might be saying - to hell with it, I'll do a re-install -although this forum has many instances of things that go wrong with that.
Even if you don't want to recover an a/c - it's a good exercise to browse the CD1 - gives a small inkling on how FS9 manages all the detail.
OK - I might be trying to teach my Granny to suck eggs but it might be useful to some one.
