Why put it in the panel. I'm sure you could mount it between the seats.
"Venus" wrote in message ... I dont know either, but when I was at the avionics shop picking up my plane recently, there was a pressureized C-210 they had just starteding working and let me peek inside. It had dual garmin 330 x-ponders, garmin 430,530 and an MX20, it also had some other nifty stuff like a flight navigator and so on.

So they go tits up that often in flight where its necessary? Scott The Twin Otter I flew had dual X-ponders. But we were using it for skydiving ops and if the X-ponder goes down, we can't operate as a jump plane. SOOoo..we had two....even had to use the 2nd one on occasion. Also, we had the panel space to spare, so it was no biggie. -John *You are nothing until you have flown a Douglas, Lockheed, Grumman or North American* |

I'm shure if you have dual Garmins the rest of your pannel space becomes
empty. Garmines pack a lot of boxes in one box. John Roncallo Peter wrote: Why put it in the panel. I'm sure you could mount it between the seats. "Venus" wrote in message ...

Scott I dunno, but maybe for the same reason some people carry along handheld radios, pocket GPS, extra batteries, 2 or 3 pencils, yadda, yadda... |

I noticed that ATP Inc. uses two transponders in their Seminole trainers.
My understanding is that because many of the ATP locations only have one plane, no maintenance shop, and operate out of class C airports, a faulty transponder would effectively ground the airplane, making a "Four day" multi course a four week course.

authorize operations without a transponder, but there's no guarantee they will. My bad, "unless otherwise authorized" (AIM 3-2-4 (d)(2)(b)) the plane is effectively grounded. I suppose the offending transponder would need to be placarded "inop" as well. |

This makes sense, but I was just looking on ASO at some senecas and about
10-15% had dual xponders. But I was also seeing them on bonanzas and others.... Scott "Brad Z" wrote in message news:MJKzb.301460$9E1.1527176@attbi_s52...

I have dual transponders. Without a transponder you are restricted in the
altitudes you can fly and you have to make position reports. Both of these restrictions can really be a major pain when flying high for any distance. BTW, in case anyone is wondering, the transponders are wired such that only one transponder is active at any one time. You set both transponders to Mode C and your code into both. Another switch determines which transponder is active. In my installation, the non-active transponder is is standby mode. jerry "Scott Aron Bloom" wrote in message ...
