The AI. In reading the FAA Instrument Flying Handbook, it says you can
derive all of the necessary flight information from the other 5
instruments.

I agree, but the loss of any one of them is not that difficult to deal
with. The real problems start when you lose more than one. And if you
lose the AI, you're probably going to lose the DG too.

Now if you have a GPS, all you need is the the TC. The GPS lags too
much to tell be useful for roll information, but it can be sufficient to
give you everything else. In a pinch. I certainly wouldn't choose to
fly IMC that way, but it might be fun to try under the hood...
