I understand your position; but given that I remain under obligation to use mark I eyeball to avoid other aircraft when VFR, I am likely to discontinue using PilotAware with SkyDemon. SkyDemon is vital navigation/ infringement avoidance software for the whole UK GA community, and I would rather maintain its continuity than see a couple of extra bits of traffic on my screen. Put simply, if I have to choose I'd rather use a GPS source in an instrument (iPad) with an installed base of 10s of millions, and a demonstrable reliability in service, than a power-hungry niche Raspberry pi setup that does a reasonable job. I still think it's a reasonable suggestion that users can choose their GPS source and traffic source independently.

Press the ? button on the banner and SkyDemon will offer to switch back to your internal GPS until your traffic receiver wakes up again.

Indeed some GUI would be nice to notify about the fallback (so I know that, no traffic information to be expected)

Therefore it's critical that "your own position" is the same one that PilotAware is using, rather than trying to mix with the GPS output of your tablet. If you're seeing GPS dropouts from PilotAware, talk to them about the best way to get a GPS antenna mounted.

1 Group: Forum Members Posts: 72, Visits: 757	+x BigJ - 4/11/2022 3:58:16 PM I would strongly support the ability to simply select traffic information and GPS sources separately. I just flew my first flight using PilotAware as the traffic/GPS source, and although I saw my first traffic (nice) I had 6 GPS dropouts in a 40 minute flight. By contrast, using my ipad as the GPS source, I had had just 2 dropouts in 150+ hours flying. So I would simply like my iPad to contribute GPS, and my PilotAware to feed traffic. +1

If you are disconnected from the source of both position and traffic data you won't get any traffic warnings anyway. Sure, but you can always stop and restart with the internal GPS only. Advantage, your log files are clean and the configuration well defined. If you switch sources there must be some documentation in the log as well. I am not convinced such autoGPS is really something I want. True (and I actually agree with you about not being yet convinced about autoGPS as you put it), but I was specifically answering tnowak’s apparent misconception.
