Noticeable, but not translatable into any sort of spacial awareness. I'm a commercial pilot with an instrument rating, but as a passenger with the only information being a sequence of variable forces, I absolutely can't tell you what our orientation is at the end of that sequence.

~2.6G is a severe hard landing. A 60-degree bank in level flight produces 2G's. One is really jolting because it happens in an instant, the other is certainly noticeable but also a more docile because it happens over time. If the 2.7G force is over a few seconds, my guess is I'd associate it with moderate to severe turbulence and not give it another thought. Do we know the duration of these forces?

Edit: Also from Avherald, Simon writes From my editorial point of view it is clear however, that the occurrence did not happen along the lines of the report that surfaced on Sunday. And I tend to agree with that, the original reporting is confused how serious the event was. Something happened, pilots self-reported, and received training.
