PURPOSE:
GNS 400W/500W Series main software version 5.20 includes the following changes:
- Added support for Garmin Flight Stream 210, providing data including flight plan (input/output) and GPS position to mobile devices over Bluetooth.
- Added support for the Vivisun tri-state HTAWS external annunciator to differentiate between the “HTAWS N/A” and “Pilot Inhibit” annunciations.
- Adjusted the width of the HTAWS Reduced Protection mode search volume to reduce nuisance alerts.
- Changed the behavior of the GDL 88 Traffic page on helicopter configurations so that the display becomes unavailable—ADS traffic targets are not displayed—when heading is invalid and ground speed is below 15 knots.
- Resolved an issue affecting the Fuel On Board setting for configurations where fuel flow is provided by an external device but Fuel On Board is not.
