FS Edit

[RAFAIR100]

I modify engine parameters in both the .air and .cfg files and ensure that they are identical.     I then check FSEdit to confirm.       Generally, the engine hp reading in FSEdit agrees with the other two files.  On subsequent restarts, however, the FSEdit engine hp frequently differs markedly from the value in the other two files.       Any ideas why?

Doesn't the .CFG file's parameters supersede the .AIR's ones, and is useful to corrects eventual mistakes or oversights of this? I've used my admittedly limited knowledge in this matter to add fuel tanks and boost or cut power on some planes in the recent past (last time I did it: today) and I've only operated on the .CFG file.

Might be that correcting both files and making so they coincide generates some kind of error? :-?

Did you restart FS after the update?

You're wasting your time in editing both the .air and the .cfg files - FS9 loads the basic flight model from the .air file first, and then applies any different values it finds in the .cfg file. So for the most part you only need to modify the .cfg file.

First to Ozzy, no I didn't restart FS9.     After making any changes to either .cfg, .air, or FSEdit, I change aircraft and then go back to the one I'm working on.        To others, thank you all.       I did kmow that the .cfg file overwrote the values in the .air file.       I just felt that it made life easier to have identical values in each file BEFORE I started FS9.       What I still can't understand is why the FSEdit engine hp value keeps changing on some aircraft.      Something is obviously changing the original input value but I can't figure out what.

I've never used the FS9 version of FSEdit. I don't know if it's been improved from the FS2000/2 versions but FSEdit had the reputation as the buggiest piece of software ever thought of. To be honest I wouldn't touch it with a bargepole & this is not just my opinion.. I'm not certain which files FSEdit reads. I always thought it was an Aircraft.cfg editor but have been told it will modify some AIR file entries as well. I'm no hotshot with FS flight dynamics but always used AirEd for AIR files & Notepad for Aircraft.cfg.

After doing any edits/modifications I find it best to exit/restart FS. This ensures the databases are properly updated & is often much quicker than changing aircraft.

Thank you, Hagar - helpful as always.       I, too, use AirEd for .air files and NotePad for aircraft .cfg files.       I think I am now going to dispense with FSEdit altogether - if it can't hold values from one load to the next, it's hardly worth keeping.

I do a lot of 'tweaking' for performance.     Sometimes, to get, for example, Vmax even close to the proper value will involve a lot of 'tweaks' on a lot of parameters.     You know, amend a value, test it, change it, try it again..........     The thought of shutting down FS and then starting up again between 'tweaks' really does depress me.     OK, nobody ever said life was going to be easy, but I can foresee that it's going to take a Heck of a long time to get performance reasonably right.      

Thanks again

It's a long time since I messed around with this sort of thing. You might find AAM useful. I was surprised it's still available.
