Hypothetical question: Ok, so your flying ATTI and lose GPS satellite signal, no problem you can continue on but suddenly you lose remote controller signal.
After 3 seconds it is supposed to RTH, what does it do?

Not sure if its the p3 or not, but after 20mins voice in your head wants you to visit store.dji.com, buy a new one and never tell anyone about it.

Possibly hover until it gets GPS back or runs out of battery & lands?  It might ascend to RTH height & wait for GPS.  It's unlikely to not get GPS for more than a few seconds.

It's a good question, but not sure if it's an issue in real life.  I've been in very built-up areas & only had slight short hiccups on my phone GPS which is supposedly much less sensitive.

You've given me an idea though of where I want to fly next, in a very deep gorge I know in the mountains.  I think I'll be using ATTI mode for that.  Maybe I'll find out...

That's it nigel.
It's not happened yet but planning to fly in locations where this might happen.
Can't find info in manual so thought I'd ask here.
I like to be prepared
