The use of GPS information as a gyro replacement, or to enhance gyro performance, has been bandied about for a while, and Garmin is first to make some application here, with the handheld GPS 196. This new unit has more features than a panel-mount GNS 530, at a fraction of the price. There's even a screen that shows an HSI, altimeter, airspeed, vertical speed and a turn-coordinator-like depiction, a kind of "partial panel" arranged in the normal pattern of instruments. The screen is big enough to be useful. The database for this unit supports all the instrument approaches, and at first sight it appears to be a wonderful backup should all the lights go out on a dark and stormy night.
