Five years. That’s how long the market has been waiting for Bendix King’s KSN770 GPS navigator. In the avionics world, a lot can change in five years, and that’s exactly what happened while the KSN770 was stalled in a lengthy R&D phase.
Touchscreen, ADS-B, advances in electronic charting and Garmin’s GTN-series navigators were a few notable changes that made the original KSN770 product nearly obsolete before it was even brought to market. Worse, the delay—and the absence of a fresh product line—created rumors that Honeywell was abandoning the GA avionics market.
