all depends on your anthro measurements. they have about 4 or 5 different measurements like elbow-to-fingertip, sitting height, etc...you fit those ranges and you're good to go. you'd probably be dq'd from the EA-6B (I'm 6'2 and they say I won't fit in one) but the F-18 and F-14 have better ranges...you could be 6'6 and still fly them if your anthros are good.
