To inject a little boring accuracy, altimeters were
built with vibrators and still are. Standby altimeters
fitted to airliners have integral vbrators and checking
that they work is on the CAA flight test schedule.

Ok, I'll be naive enough to ask. Was that intended
to amuse us, or do
you really not know what they were for?

The sentence is from a paragraph that explains altimeter
lag, and how
to work around it.
