Light Sport Aircraft (LSA) is actually a certification category for aircraft designed to the ASTM standards. It originated in the USA and allows manufacturers to self-certify aircraft with a maximum take-off weight not exceeding 600kg. In Australia, the term LSA is often used generically to describe fixed wing aircraft (including “Primary” category planes) which are heavier and higher performance than traditional ultralights but which are lighter than General Aviation aircraft.
The qualification required to fly them is the same pilot certificate issued by Recreational Aviation Australia that is needed to fly microlight trikes or ultralights. Conversion between the different types of aircraft is not difficult but does require some difference training.
The Sling 2 is designed and built in South Africa and cruises in excess of 110kt whilst burning around 18 litre of unleaded car fuel per hour. It features a low-wing, an enclosed cabin with two-seats-in-side-by-side configuration, fixed tricycle landing gear and a single 100HP engine.
