IFR GPS question

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.

Yes, but irrelavant to the discussion.

You missed the root of the problem completely.







The reason why you can't file such an
alternate is that you don't have the minimum information required to
safely fly that approach.




No, that's not why. As a matter of fact you do have all the
information. The reg is there to provide redundancy.

Oh? The question Robert asked was whether he could legally fly VORDME
approaches if he removed his DME after installing the 430. I thought
Thomas Borchert gave a very good reply, which seemed clear to me. I'm sure
that my IFR training, which is not very deep, may lack some practical
point about this, as I don't see how a reg that requires you to specify
the equipment on board could allow one to file an alternate that requires
equipment that you don't have. If I have that wrong, I would appreciate
your clearing it up for me.

Not quite. You can't file that airport as an alternate if you need
the GPS to get in there. However, once you actually =need= an
alternate, that restriction goes away. It's a restriction on filing,
not on flying.

Going to an alternate isn't an emergency.

An "alternate" only exists for filing purposes. After that you're
just changing your destination. The minimums, equipment requirements,
etc... are the same.
