Pilots approaching six feet will want the pedals extremely forward and the seat back in the aft hinges, fully leaned. Of course, some six-footers might want it more crunched; it's easy to shorten dimensions, but impossible if you don't make provision. So, make the pedals adjustable at least 3" aft from extreme forward. I've flown five-foot plus a smidgen pilots whose feet where 3" shy of the forward pedals. Simply moving the seat back forward crowds the stick, deletes thigh support, and the seat cushion fit - doesn't.
