My worry about Android devices is the relative lack of aviation apps for them, but with Garmin Pilot, that concern is answered. The Android app, which has gotten very little notice in the aviation press, is nearly as good as the company’s fine iOS version, lacking just a few features, like the panel page, split screen and flight plan filing. What you do get is Internet and, with an external receiver, in-cockpit weather — with the GDL-39, you get free ADS-B weather — crisp and zoomable charts, VFR charts, IFR low and high en routes, flight planning and airport information pages, all with a few swipes of the finger. There’s Safe-Taxi surface awareness charts — all are geo-referenced — and much more. And Garmin has steadily updated its Android app, so it’s only going to get more features as time goes along, with all of them rolled into regular product updates.
