In terms of software, the killer app on the 796 is synthetic vision, which Garmin, for its portable products, refers to as 3-D vision. Arrayed around a sharp and smooth synthetic vision window are an airspeed tape (groundspeed, actually), an altitude tape (again, GPS altitude) and, along the top, a heading (track) indicator reference. While pilots flying steam gauge airplanes might be tempted to rely on the 796 for attitude, they are cautioned against doing that. It is not an attitude-based system; it derives its position information from GPS. If steam gauges are your thing, there’s also Garmin’s already well-known “panel page,” which shows a cluster of virtual flight instruments with its information derived, again, from GPS. There is, as with other Garmin portables, great terrain awareness, with obstacles, TAWS-like color-coding of terrain and GPS altitude readouts.
