Avidyne Corp., Lincoln, Mass., added synthetic and enhanced vision capabilities to its Entegra avionics suite. The announcement was made at this week’s EAA AirVenture trade show in Oshkosh, Wis. The synthetic vision system depicts 3-D terrain all the way out to the horizon, based on the aircraft’s altitude above the ground. Avidyne said its system also depicts obstacles, traffic and “Highway-in-the-Sky” boxes on the primary flight display. Avidyne’s enhanced vision system uses a Max-Viz EVS-100 infrared camera.
