You can check your score ingame by either
- open roster, find your (or any other name), rightclick on it and then lcick "score"
- or use the score dotcommand: just write
.score HANDLE into your radio text buffer. "Handle" being the handle of any pilot. If you just type ".score" without any name, it will automatically show your own score.
Score can be checked on webpage the the way LancerVT just described. It's a bit more detailed than the ingame score function in some ways.
If you select "Kill Stats in expanded format" you can check for example what planes you (or any other pilot) were flying and what plane types you shot down (or killed you)
Finally, there is no such thing as an "Ace" status in Aces High 2.
EDIT:
"regular scores" ? tour scores are the regular ones. There are no others. If you are a freeloader - no soup, err, scores for you
