A good friend of mine is a physician and a pilot. (No, there isnt a Bonanza in his hangar; he happily flies a Mooney Ovation.) Ive always found him to be a very safety-conscious pilot. He gets an IPC every six months and does other periodic training. When he wanted to do something different, I suggested he get an airline transport pilot certificate with an airplane single-engine land rating. (ATP-SEL) Why? was his first reaction. I dont need it for the kind of flying I do.
