"Partial panel" is a staple of IFR training, and the filght test.

Partial panel is also a reason to land at the first opportunity.

I've never played with VATSIM, so here's a question you might be
qualified to answer......Can you play with partial panel emergencies
on VATSIM. That might actually be kinda fun.

VATSIM allows emergencies within reason. You can declare an emergency, but
unlike real life, ATC has the option to decline the emergency if it is too
busy to handle it. The reason for this rule is that some pilots would tend to
declare emergencies excessively otherwise. As it is, total engine failures
are suspiciously more common on the network than in real life. But most
people behave.
