Owners of Garmin's GNS400W and 500W models can now get a long-awaited WAAS software upgrade that resolves many compatibility and functionality problems and gives users access to more XM WX satellite weather products, including lightning, cell movement, and winds aloft.
The upgrade, which includes a new flight manual supplement and takes about one hour to complete, is available at no cost, but access to the additional XM WX features will require an Aviator package subscription.
With the software upgrade users will get enhanced features that make it easier to load arrival and departure procedures, reduce TAWS nuisance alerts for circling approaches, allow users to store up to 15 radio channels, improve the auto-zoom function, and give better VNAV functionality during holds.
Other changes correct winds aloft calculations, stop intermittent screen flashing, and start the unit in the last mode used. Users will also see improved compatibility and functionality with certain Stormscope, Avidyne, and Honeywell products.
For more information, consult your avionics technician.
