History

The EM-11 was designed by Edward Margański of Margański & Mysłowski Zakłady Lotnicze (Margański & Mysłowski Aviation Works), who were previously known for their Swift S-1 and MDM-1 Fox sailplanes. Work on this new low cost, light utility aircraft, of unorthodox configuration, with slim glider-like fuselage and two pusher engines, started in 2001 and was constructed of composite materials with a 4-seat cab placed low, for easier boarding. Luggage is stored behind the rear seats. Composite fuselage was a development of sailpane fuselage.[1] As the designer Edward Margański pointed out, his goal was to create flying limousine "for people, not only for pilots", offering good visibility, comfort and ease of boarding.[1] He expressed also, that his ambition was always to create beautiful aircraft, an in this field his inspiration was Let L-200 Morava.[1]

First prototype EM-11 Orka SP-YEN

The first prototype EM-11, registered SP-YEN, flew 8 August 2003.[1] It has a fixed tricycle landing gear and Rotax 912 (100 hp (75 kW)) engines. The second prototype, registered SP-YEP, was to be a pattern for serial production variant EM-11C, flew 20 October 2005 with Lycoming IO-320 engines and retractable landing gear. In April 2011 EM-11C Orka was EASA certified and is currently in production. Prior to certification, two prototypes and three further aircraft had been built.

Several variants are planned including, a patrol aircraft with an FLIR head, an air ambulance, a cargo aircraft, and an amphibious version.
