I've never heard that you could use your military flight physical to fly civilian planes. I mean I still had to get my 1st Class (@ $180) even though I had my Class 1 flight physical the month prior. Until recently a military flight surgeon couldn't give anything other than a 3rd Class (at least any that I have asked or encountered) FINALLY last week I found out that one of our Reserve Flight Surgeons is now qualified to give 1st Class medicals! FINALLY!
