The GWX 70’s compact, all in one antenna, receiver and transmitter is designed for easy installation in a wide variety of aircraft. Available antenna sizes include 10, 12 and 18 inches. The Altitude Compensated Tilt (ACT) feature helps reduce pilot workload by eliminating the need to reset the antenna tilt with changes in aircraft altitude.  

The pilot simply adjusts the GWX 70 once to the desired tilt angle, and the radar will automatically adjust to that level during any change in altitude, allowing the pilot to focus on other important tasks in the cockpit. Garmin’s exclusive WATCH™ feature (Weather Attenuated Color Highlight) helps identify the shadowing effects of storm cell activity, highlighting areas where radar signals are weakened and may not fully reflect the “storm behind the storm.” 

The GWX 70 offers horizontal scan angles of up to 120 degrees. To focus radar scanning on a specific area of interest, the GWX 70 offers pilot-adjustable sector scanning from twenty degrees to 120 degrees. Ground mapping mode lets the pilot use the GWX 70 to scan terrain features for visual navigation. And the system also includes a vertical scanning function to aid in analyzing storm tops, gradients and cell buildup activity at various altitudes. 

Optional Doppler-enabled advanced features are available including turbulence detection to identify turbulence in air containing particulates, such as precipitation or dust, out to 40 nautical miles. Ground clutter suppression is also available as an option, which allows the GWX 70 to separate radar ground returns and remove them from the display, so the pilot can focus on the weather of interest.
