Span and Height for the Aircraft
The clear span has to take the widest wingspan or rotor diameter, with room to move the aircraft in and out. Spans reach up to 20 m on the aluminium system and up to 30 m on galvanised steel, with eaves heights of 3 to 7 m depending on the system. Larger aircraft are designed on the structural steel system, where the span and height are bespoke.
