RadAlt HTAWS ADS-B Check. Check. And Check. Better situational awareness makes flying safer for all of us. That's why, early this year, the FAA enacted new rules for commercial adoption of both radar altimeters and HTAWS (Helicopter Terrain Awareness and Warning Systems). Radar altimeters will be required for all Part 135 operators - and air ambulance operators will also be required to equip with HTAWS - by April 24, 2017. What's more, most aircraft flying in U.S. controlled airspace will also need ADS-B "Out" capability by year-end of 2019. All of these technologies are aimed at helping pilots keep their distance from flight path hazards: With visual and aural advisories. Crisp 5-color terrain shading displays. Real-time traffic alerts. And with voice callouts that announce height above terrain when descending below 500 feet. For all these must-have solutions, Garmin is your go-to source. So why wait? Call your dealer now to avoid that last-minute scheduling crunch.
