When in Go Flying mode, the connection to a third party device can fail, e.g., Sky Echo batteries running out, PAW instabilities due to poor charging connector, loss of GPS signal. It would be very useful to be able to switch back to Location Services without having to leave the Go Flying mode (and having to start a new flight, losing timers and having to stitch the two flight together afterwards).

I also have had 2 incidents recently when SD lost connection with SE with a consequent loss of position fix. Both a little stressful.
In the first case it resolved spontaneously after a minute or so. In the second case, I had to reset SD with a new flight which is not ideal.
I have emailed SD to suggest they upgrade the software to default to the iPad GPS in the event of a loss of connection to SE or at least offer this as an option in the setup.
I would suggest that avoiding a loss of position suddenly is more important than a loss of traffic info which could be flagged up anyway as a banner if there is a loss of connection to SE.
