Great question! FlyQ EFB is supported by virtually every avionic manufacturer except for Garmin (closed system). The industry uses "open standards". This openness lends to "universal compatibility" which benefits both customers and manufacturers. This is not a technical limitation on our part. We welcome all manufacturers to add support for FlyQ as it would allow customers the freedom to choose an app that best fits their needs. If you would like them to add support for FlyQ, please let them know at: email@example.com and firstname.lastname@example.org.
If you haven't purchased a yet, popular choice among pilots is Appaero ES series, L-3 Lynx NGT series, and FreeFlight Systems Ranger series.
