Dynon SkyView HDX

Each SkyView display connects through its own harness. Dynon also sells displays as bundles with the harness included; choose that if you buy them that way.

The ADAHRS gives the displays attitude, heading and air data; the OAT probe comes with it. A second ADAHRS keeps the flight instruments going if the first one fails.

The displays need a GPS position. The SV-GPS-2020 meets the FAA's ADS-B Out rule when paired with Dynon's transponder; the SV-GPS-250 does not. Choose Another GPS source if an IFR navigator on the panel feeds the SkyView.

The engine monitoring module reads the engine sensors and shows them on the SkyView. Rotax 912 iS and 915 iS engines connect to their engine computer instead, through the SV-EMS-221.

Dynon's autopilot servos move the controls. Roll only holds the wings level and follows a course; pitch and roll also holds altitude and climbs or descends; a third servo adds a yaw damper.

A transponder run from the displays. With the SV-GPS-2020 it gives ADS-B Out, required in most controlled airspace.

A receiver for ADS-B traffic and weather shown on the displays, on both ADS-B frequencies. No subscription is needed in the United States.

A pitot probe that also measures angle of attack, for the displays' AOA indicator. Choose heated for flight in visible moisture; the heated probe is for 12 V systems only.

Extras that work with the SkyView. None is needed to fly; tick any you want and they join the list.
