Schaefer, I don't think BMI matters too much. There were some pretty big boys on my BFTS course and they got to be quite large as it progressed, with no PT and too much canteen food! I was on the other end of the spectrum, being wafer thin. The Wing Commander just told me to each more steak at the Officer Board because I was too light for the ejection seats, eg under 62kg! They take all sorts of body types. There were some instructors up there who looked like they'd exceed the MTOW of the aircraft they flew, so I wouldn't worry too much
