Dual Transponders?
Ok, Im not talking about the commercial carriers. But why would a general
aviation plane have dual transponders? Why waste the panel space? So they go tits up that often in flight where its necessary? Scott |

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.

Ive seen a couple of GA aircraft with em, and more than plenty of biz
jets that DONT.. I dont know the rhyme or reason. If I was limited on panel space, Im sure a 2nd xponder would be low on the list.

How does a second transponder fit in to the datastream? Aren't they both
transmitting the same data at the same time on the same frequencies? Wont that interefere with itself? Jose -- (for Email, make the obvious changes in my address) |

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.

A faulty transponder COULD effectively ground the airplane. ATC can authorize operations without a transponder, but there's no guarantee they will. |

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...
