Approach selection resets following external GPS connection loss

I sometimes experience temporary (5-15 second) GPS signal loss, which I suspect is a tablet issue and am investigating further - the purpose of this post is to describe SkyDemon behaviour when that happens and an approach has been selected for a destination airfield. When the external GPS signal drops out and returns, SD behaves mostly as expected and a seamless re-connection occurs (depending on the length of dropout I see the message counting number of seconds without a signal until reconnection). However, if an approach has been selected, the selected approach is lost at this stage, and needs to be re-selected as though for the first time. This is a slight annoyance but it would be good if SD could retain the selected approach following an interruption of GPS signal reception. Is that a simple fix?

I had a GPS connection dropout (SkyDemon alert banner showing without signal for >10 seconds and counting up). The signal returned after est. 12 seconds and all Navigation was then as before - except that the approach sub-window had reverted to "Select Approach"

There are a number of situations where the approach can be reset and we need to fully reproduce your situation to be sure of which one we are addressing, and its potential side-effects. We will come back to it in a few weeks.

Group: Forum Members Posts: 47, Visits: 205	Thanks,Tim. I don't think it's more than a relatively minor annoyance when it happens and doesn't appear to happen for everybody anyway. Resolution in a few weeks sounds good. Would any data from the Turweston flight be of use to aid in an investigation to reproduce?

Group: Forum Members Posts: 7, Visits: 26	Hi there - I have the same problem when practising using Prepar3d - the GPS keeps disconnecting, and SkyDemon forgets the approach. Not sure what the best way to connect SkyDemon to Prepar3d is but the 'x-plane' way does not work well. The virtual radar also keeps resetting and dropping out. Is there a preferred/tested way of using Prepar3d to practise flights connected to SkyDemon? Cheers in advance for any advice.
