No; it doesn't refer to aviation medical exams either.

I honestly have no
idea what it is supposed to refer to. It's an option in Falcon 4.0; FreeFalcon3 upgrade. It is a configuration of something - FF3 refers to it frequently and it is a selectable option in the config editor: 'Cat III Default'. I
believe it has something to do with weapons loadout - whether a Cat 1 is A-A and 3 is A-G or something; I couldn't say.
I went online to see if I could find the answer and found plenty of examples of the term - particularly CAT-I; which seems to be the more common whatever-it-is of the two. The problem is that to folks who know the F-16; the term is so common no-one feels the need to describe what it actually means.

I'm playing the sim on full realism settings; starting missions from full cold 'n dark configuration; full realism on the avionics etc. It is - to put it mildly - a major challenge;
far harder than anything in M$ FS's. Whatever these particular Categories are; it seems to be not too critical since my jet flies and fights quite well without knowing - but since I'm going for full realism; I might as well learn what the terms mean.
Driving me nuts too!
