Cabina Larga
Standard Cockpit - for up to 1,85 m tall pilot. Taller pilots can use higher cabin hood which is possible to make up to 5 cm (2 in) over standard one. Another possibility is longer cockpit for another 5 cm known as “XL”. This version is comfortable even for 2 m (6,6 ft) tall pilots. The weight penalty for XL cabin hood is app. 0,5 kg and for XL fuselage another 1 kg.
At least SE-33 engine should be used on an airplane with XL fuselage.
