Garmin’s most advanced weather radar system is certified and available for Piper Aircraft’s M-class line of aircraft, the company announced July 26 at EAA AirVenture in Oshkosh, Wisconsin.
Turbulence detection and hail or lightning prediction help pilots to avoid turbulence in flight by recognizing air that contains moisture or particulates, according to Garmin. Areas of likely turbulence can be depicted out to a range of about 40 nautical miles. Identified areas of hail or lightning are displayed as yellow Xs or magenta triangles.
Weather attenuated color highlight technology points out shadowing effects of cell activity and highlights areas where radar returns are weakened or attenuated by intense precipitation, Garmin said.
Optional predictive wind shear identification detects “a combination of updrafts and downdrafts and Doppler-effect that result in wind shear formation,” Garmin said. This feature is fully automated throughout the takeoff and landing phases of flight. “Pilots receive aural wind shear notifications, as well as visual indications on a dedicated Garmin display.”
Scan/refresh rates on radar images are four scans at five seconds plus five seconds for processing, or 25 seconds between images, Garmin said.
Garmin announced the GWX 8000 in April. The system will sell for $20,000, Piper said.
