This is equivalent to the angle at which the wing is intercepting the body of air surrounding the aircraft – exactly the same as a probe based AoA system. The AV-30 does not currently support vertical navigation display, but this feature will be introduced with the APA-10 autopilot interface box.Īngle of attack is determined by comparing aircraft pitch to the actual flight path angle through the air. When operating as an attitude indicator, it can drive the direction tape and provides a bearing-to indicator. This data can be overlayed in the textual fields as desired and is used to create the compass rose (GPS Track), moving map display (ARC Mode), and create the GPS HSI presentation when the AV-30 is operating as a DG instrument. The data provided includes current waypoint ID, distance to destination, ground speed, cross-track error, desired track, and bearing to waypoint. When connected to an external GPS navigator or hand-held, AV-30 operates as a repeater display. NMEA protocol supports baud rate speed of 48, while “Aviation/moving map” protocol is fixed at a 9600 baud rate. NMEA is also supported, which is output by most hand-held GPS units. This data is broadcast by the GPS navigator and no data is sent from the AV-30 back to the GPS unit. The AV-30 provides an RS-232 receive line for “aviation” or “moving map” output provided by virtually every panel mount GPS navigator in service.
