The Cirrus SRS (SR Sport) is the German B&F Fk 14 Polaris all-composites two-seat ultralight modified for US LSA regulations. First flowing in 1999, it was selected by Cirrus after a four-year evaluation of various designs. Powered by a 100 hp / 75 kW Rotax 912S, Cirrus will have to slow the aircraft down to meet the LSA’s 120 kt / 222 kph maximum cruise speed rules.
