The Auster Avis was a four-seat light aircraft developed from the Auster Autocrat.
It featured a redesigned fuselage incorporating four doors and a circular cross-section towards the tail, new undercarriage, and new wing flaps.
It was planned in two versions, the Mk 1 for civil use, and the Mk 2 for military and air ambulance duties.
However, only two prototypes were built, and Auster abandoned the project in favour of the Auster J-5 Autocar.
