The height limit is quite high for pilot/nav, its just the leg and arm lengths etc that most people fail on. I failed the medical for pilot/nav on my buttock-knee length by +1mm, someone else on my board failed coz her arms were too short. There was a lad there who passed the medical who was taller than me
, but his legs weren't as long.
I'll tell you about it at the next notts bash
