My husband's 6' 3.5" or 1.93m. He has a long torso and short-ish legs. Some aircraft are a squeeze but he can fit in most. Nowadays it's his mass that's the restrictor for aerobatic aircraft etc.
He flew Bae 146, B737 and now A320s with no dramas.
He was also accepted into the RAAF as a pilot cadet too. His thigh length was short enough - just.
We have a guy at work who's 6'7". He's Dutch and they're generally pretty tall. He folded himself into the Hawker but was too tall for the Bravo, Phenom and the H400.
