I found that some aircrafts use both numer formats in the same file aircraft.cfg : [cameradefinition.1] [cameradefinition.2] etc... and then [cameradefinition.001] [cameradefinition.002] etc... Why to use both formats ? I tried to find a connection between those formats and cameras.cfg but it doesn't seem to have one. How can FSX distinguish one from the other ? In the SDK help files I didn't find any answers. Is weird because I have found this pattern in both Addons and MS aircraft.cfg's files. Could someone give me some light on this subject ?
