As said before, you can't get your IFR rating with just a GPS, you still need something else. I use a VAL Ins-429 all in one unit that provides VOR/LOC/GS and MB in one unit. With this in your aircraft you can get your instrument rating.

First of all, thank you all for your valuable input. This is great info.

What I dont understand, FAR 91.205 does not refer to a backup system.

"(2) Two-way radio communication and navigation equipment suitable for the route to be flown."
That's a rather vague description.

If I have 1 GPS to fly enroute and fly an LNAV approach, that seems suitable to me ? Reasonable ? No.
Is there another regulation i am missing ?

Sorry I did not mean IFR rating, I meant IFR requirements.
I already have my IFR rating and thousands of hours flying commercial.

"suitable for the route to be flown" Also means the navigation equipment has to be approved for IFR.

So if you have a non-WAAS box what if you have a RAIM failure enroute or at your destination?

Actually a great point but irrelevant to what he is trying to do. This is the answer:

Anything else depends on your level of risk tolerance.

It is if all he's got is a non-WAAS GPS and no NAV radio which is what I understood he was proposing based upon the original post .

This is indeed what I was asking, but I also know that I wouldn't necessarily be comfortable with it.
I wanted to understand the minimum to get away with, and then add on what I think makes sense.

"route to be flown" does not include the approach, which would have different requirements, is this what you mean ? Makes sense.

Actually, my understanding of 91.205 is that it does include the approach. In any event I'm just not risk tolerant enough to not have more than one navigation system for IMC ops. YMMV....

There's one other issue. With a non-WAAS box you'll need a second non-GPS nav system in order to legally file an alternate if the WX is worse at destination than the 1-2-3 rule.
