I had the option to fly in a G1000 equipped 182 when in the US two weeks ago. The trouble was that I was there to do an IR checkride so would have had a lot to learn to operate it and besides it struck me that I ought to be doing the checkride the traditional way. I would have been surprised to learn that you can do a checkride with a glass panel aircraft had it not been for a recent article in the US AOPA Pilot magazine. The author was describing how, as somebody (with an IR) who has only ever flown IFR with a glass panel, they tried out some limited panel work in a standard IFR fit aircraft and struggled. Seems that partial panel in a glass panel aircraft means you have to get by with an ASI, AI and Altimeter! They ought to just go the whole way and stick a TC, DI and VSI in there as well for good measure!
Of course the other reason for not trying the glass panel aircraft was that I suspected that it was likely to cost me considerably more than the cost of the rentals!!!
