I have a question regarding all aircraft, including military over 12,500 lbs to be required to have on board two transponders for redundancy. Does such a regulation exist?. Example, Boeings, A/Buses, C-130's P-3 Orions, C-117's etc. If both are inop can the type be allowed to fly in controlled airspace. Sure I know the answer, but I would like to hear from someone in the know...thnx...g

Depends on the airspace requirements. If it is required, you can always call ahead and get approval.

As far as FARs are concerned, no, not to the best of my knowledge, unless there's some obscure FAR I don't know about that applies to the military only. So I'm guessing the dual transponder rule is just a military requirement, as they have pretty much their own regs and SOPs

Yes. You'd basically get a hold of either FSS or the Radar agency with jurisdiction of the airspace you intend to fly through and let them know beforehand you're coming through. No biggie really.

However, whether the military will actually allow that to be done is a different story.

Thanks for the responses...but on the types I mentioned, is it typical in avionics layouts to install 2 transponders, not just 1?...g

I would imagine so. I've seen quite a few business jets that have two transponders installed. Heck, I've even seen single engine pistons have 2 transponders installed, just in case. Not a lot of additional cost, and the redundancy to keep going if you've got troubles with one.

I've flown twin turbines and twin pistons, and i've only seen two transponders in both! That being said most training planes have only 1 transponder because the school is likely too cheap to shell out for a second.

Sometimes though, there may appear to be only one transponder when in fact there are two. The control face has a toggle switch from Trans. #1 - Trans #2. There are indeed two separate systems onboard, but the control face plate can control either.
