ForeFlight Mobile, a premier application that can be used with Connext, wirelessly communicates with Flight Stream 210/110 to display ADS-B traffic and weather information received from the GDL 88/84. The internal attitude sensor within Flight Stream 210 also powers ForeFlight Synthetic Vision with dynamic pitch and bank information. Highly accurate WAAS GPS position information provided by the GTN? 650/750 or GNS 430W/530W navigators or GDL 88 with an internal WAAS receiver, is also shared to display precise position information on ForeFlight Mobile?s moving map view. Connext compatibility is available today and additional capabilities are expected in the future.
