Has anyone seen this before?
Whilst carrying out a turn on a taxiway, I watched as the AI in my 152 began lazily indicating a 20 degree bank in the same direction. It didn't settle down again until the a/c had been stationary for a minute or so.
The vac was (just) in the green, so I assume it is the AI itself that is up the spout?

...was that TO or FROM?
