A spirit level does not work in an accelerating frame of reference. From the point of view of a spirit level, there is no difference between straight and level flight (1g due to earth's gravity) or a spiral dive (>1g due to a spiraling turn downwards).

Gyroscopes work, which is why artificial horizons are a thing. But an artificial horizon doesn't show anything except where your nose is pointing. You need all sorts of other sensors to tell you which direction you are actually going.

Not smarter, just an aviation layman geek :)
