Just curious

Wanted to know if you guys occasionally practice, at a safe altitude
with not too many passengers on board, stuff that *might* come in handy
should something dreadful happens - for example, shutting off an engine
or both and trying to judge, from the aircraft's rate of descent and
distance covered between two altitudes, how far ahead it can possibly
reach before reaching the ground, etc. Just to get a feel of things
real-time.

Or is all of this restricted strictly to simulators?
