Fitting
Short guys and tall guys out there,
Just went for a fitting session with OAT and found myself to fit alright in the piper warrior and senaca. I sit and reach comfortably in their 737-400 simulator too. I am 5'4". The basic requirement is to be able to reach full rudders and apply full aileron in the same direction without any obstruction, and to see over the instrument panel out of the aircraft. You must be able to reach for the instruments in the cockpit too.
This guy who is about 6'6-7" fits alright too.
One point to note is that OAT's sims are not Type sims. Hence the fitting result might not be a true gauge.
