Jim Frantz gently reminds us that the need for the second NAV/COM we're all used to stems from the unreliability of the radios we grew up with, and the reliability of today's radios makes their duplication unnecessary.  However, I think he went overboard in a couple of his comments.  For the record, I have an IFR Cessna 150 with one com, two navs and a DME, and some of this equipment will be transferred to the Lancair when the time comes.  I plan on two COM radios, at least one NAV, plus either a DME or GPS. (Of course, if Santa dropped off a Garmin 530 I wouldn't need anything else but the second COM...)  Specific rebuttals follow:

<<The proper procedure for retreiving ATIS is to get a clearance from the controller to go off freq.>>

Maybe, but switching from ATC to ATIS is a pain in the butt, especially when it's a busy day down here in Southern California (probably works well in Minnesota, though, and other less congested areas).  Occasionally I fly an aircraft with two COM  radios and I prefer getting ATIS without dropping off the main line.  No problem missing clearances since I don't listen to ATIS when copying clearances.  Besides, it's amazing how hearing your call sign focuses your attention on the air traffic controller speaking to you on COM 1.  No problem tuning out ATIS then since their story repeats.  Sure wish I had a second COM in my 150, and you bet there will be one in the Lancair.

<<The 2nd COM is kind of like having a second wife, it's useless, expensive and complicates life.  Same goes with the 2nd NAV.>>

I actually get along better with my second wife than I did with my first.  I presume that Jim was talking about having two at the same time.... <G>

I would hate to live with only one NAV if I didn't also have a DME or a GPS.  I had the misfortune of flying a rental 172 with a single coffee-grinder NAV and it was a much higher workload than I liked.  A flip-flop frequency selector would have helped, but the DME (or GPS) is a much a better solution. I agree that a second VOR is not required, but in its absence a second positioning device is needed.  I would opt for a DME before a second VOR.

That's my 2 cents.
