Yes, that is the nature of a vacuum pump failure. What warning were you
expecting?


The new Cessnas have dual vacuums, which I think is an excellent
safety feature.

In my opinion, a better alternative (and one available for virtually any
airplane) is a standby electric AI. Also, most GPS units provide an "HSI"
functon that will provide a workable backup for a vacuum DG.
