FBWB Flight mode and GPS Signal loss

Hello,

I’m wondering if the FBWB flight mode has any issues when GPS signal is lost.

For example, if I’m flying my VTOL over the sea on a ship, in a long distance, and the GPS signal is lost or interferes, can I switch to FBWB mode to return back to the ship, relying solely on the compass and FPV screen?

I was going to say yes, you can still use FBWB, but I just double checked the wiki and it says that FBWB uses the GPS. I wonder if you have a compass functioning then that might not be an issue. I know cruise would be out of the question without GPS. That said, since most compasses are in the GPS, if you’ve lost the GPS you’ve probably also lost the compass. I know FBWA will work.

I have GPS for yaw so maybe I have to use internal compass.

FBWA is too dangerous when use with delayed FPV screen, so I think arduplane should work in FBWB when GPS signal is lost.

FBWA can be used with telemetry HUD it should be much faster than FPV
