TwinStar N238US comes with both an activated SiriusXM satellite aviation weather and radio package, providing features to the pilots that are especially useful on longer X/C flights:
- In-flight WX features that are generally still superior to those provided by ADS-B In (FIS-B) due to better availability (as there is no dependency on ground stations), faster updates, and more weather products are available on N238US’s G1000 MFD (and PFD inset map), where no NEXRAD/FIS-B is provided by ADS-B – XM WX bridges that gap by giving the pilot a dedicated Weather Data Link map page as well as NEXRAD on the default and FPL map pages (and the PFD inset map)
ADS-B will likely catch up on some product differences over time, but the line-of-sight difference will not change in this specific technology comparison.
- In-flight XM satellite radio offering 150+ stations for plenty of music, fun and information. The radio sounds fabulous on an ANR stereo headset, and music gets automatically faded out and back in for all communication.
In 8US, the two switches below the headset plugs can control the XM Radio in addition to the softkeys on the PFD Aux page
While you can see important weather aspects on the moving map such as NEXRAD, lightning and cell movements, most relevant information can be retrieved from the dedicated Weather Datalink map page.
Make sure to read the Hazard Avoidance section and also search the G1000 Pilot’s Guide for SiriusXM to understand how to access the XM weather features.
If related certification issues can be resolved then N919ES will also be provided with the same XM features as N238US in Fall 2020 (except for the additional hardware switches on the intercom panel).
