Garmin announced an updated version of its Garmin Pilot iOS app that includes synthetic vision as an option for premium subscribers. Dubbed SVX, the new feature displays GPS-derived airspeed, altitude and vertical speed overlaid on a 3-D topographic landscape. When paired with Garmin’s GDL 39 3D Bluetooth ADS-B receiver, back-up aircraft attitude information can also be displayed on top of the synthetic display in Garmin Pilot. The Garmin Pilot app is free, but an annual subscription (starting at $74.99 per year) is required.
