Well, *all* restrictions go away in an emergency, so that doesn't really
address the root of the problem.

Diverting to your alternate is not an emergency, nonetheless, you are
permitted, once in the air, to divert to any airport you want, with any
approach you want (that you can fly). The point of the filing
regulation is to ensure that you carry enough =fuel= to fly to an
alternate that doesn't require your GPS.

It's a fuel on board for flight planning thing, that's all. Once in the
air, it goes away, emergency or no.
