While regulations do not specify what type of aircraft must be used for flight training, Inspire Aviation uses only RA(Aus) Approved single-engine aircraft. Flight schools typically use both two- and four-seat aircraft with one engine and fixed landing gear. Most training aircraft fly at around 150 kmh and can stay aloft for over four hours at a time. Speed is not important during the learning stage, because students must concentrate on how to fly rather than where to go. Once students become private pilots, they may go on to fly advanced aircraft with sophisticated navigation systems, and six-passenger capability.
