Gwx 70 Weather Radar (Optional); Charts (Optional); Transponder Control (Optional); Telephone Audio (Optional) - Garmin GTN 625 Flight Manual

7.14 GWX 70 Weather Radar (Optional)

The GWX 70 Weather Radar uses Doppler technology to optionally provide
advanced features to the flight crew such as turbulence detection and ground
clutter suppression. Turbulence detection can detect turbulence up to 40nm from
the aircraft and will be displayed at radar ranges of 160nm or less.
Turbulence detection does not detect all turbulence especially
that which is occurring in clear air. The display of turbulence
indicates the possibility of severe or greater turbulence, as
defined in the Aeronautical Information Manual.

7.15 Charts (Optional)

The GTN 750/725 can display both procedure charts and weather data on the
main map page at the same time. When datalink NEXRAD or Precipitation is
overlaid on the main map page, the weather data is displayed below an overlaid
procedure chart. When airborne weather radar is overlaid on the main map page,
the radar data is displayed above an overlaid procedure chart.

7.16 Transponder Control (Optional)

The GTN can be interfaced to a Garmin transponder for control and display of
squawk code, mode, and additional transponder functions. The activation of the
"Enable ES" button on the transponder page does not indicate the aircraft is in
full compliance with an ADS-B Out solution in accordance with TSO-C166b
(1090ES). Consult your transponder documentation for additional information.

7.17 Telephone Audio (Optional)

Telephone audio distribution to the crew defaults to OFF on each power cycle of
the GTN. Prior to utilizing the telephone function, the crew must distribute
telephone audio to the desired recipients. If the crew is utilizing the telephone
function it is required that the telephone audio be turned off upon completing
telephone usage.
