Re: Obviously not GPS jamming
Inertial navigation drift is a bit worrying - shouldn't routine maintenance pick this up?
Nah, drifting's fine, just don't kerb it too much. So being a tad curious, the aircraft seems to be operated by Jota Group, who do motorsports stuff. So going around in circles is normal, as long as it's roughly on the right track.
But I guess it's one of those things. As long as the pilots know where they are, all is well. If they aren't sure, I guess they can always ask air traffic controllers, or hold a sign up in the window for the nearest Typhoon QRA. Or I guess it's one of those faults one detects when all the other navaids have failed, and it looks like you're set for landing in the North Sea. But I'd have hoped the avionics did some sanity checking so if the various navigation systems had a disagreement, there'd be some sort of warning, either to the pilots, or ground crew. I'd always thought that for an aircraft to be considered airworthy, especially carrying paying passengers, all it's systems were meant to be in order.
