Glass Cockpit

Avionic equipment

Modern Dynon SkyView 10” digital instruments on both sides of the dashboard ensure the clear display of flight and engine indicators. Flight data display is duplicated thanks to certified analog instruments – speedometer, altimeter and compass. The ELT safety transmitter is part of the left panel. Modern communication devices, navigation radio (NAV/COM) and transponder allow seamless communication of the crew with the surroundings. An important part of the equipment is a certified artificial horizon located in the middle part. The instrument panel is characterized by ergonomically positioned and clearly arranged avionic equipment and trouble-free operation of all instruments. With an emphasis on safety and simplicity while maintaining the highest possible level of comfort.

Flying beyond the horizon

Night flying and Night-VFR qualifications are very interesting and important for several reasons. Both the pilot and the aircraft eligible for this type of flight can extend the flight even after dark and enjoy the beauty of night flying. This elegantly prevents strict adherence to the time limit for landing or approaching dusk. Night-VFR pilot competence also means excellent preparation for obtaining additional certificates, such as IFR, IR(A), instrument flying. A successfully mastered Night-VFR qualification is often the essence of a dream career, becoming a traffic pilot. Top VFR-Night features are documented by the following aircraft configuration.
