Filing Flight Plan
I was browsing some Piper Malibu's on Controller.com and noticed that some have dual transponders. Why dual? Is it for redundancy? Or is there a pratical use?
Redundancy.
How so?My Cardinal's primary transponder is controlled by my CNX-80, and if either the control link or the GPS itself fails, there is no way to control that transponder as it is mounted somewhere in the tailcone, not in the panel. So the previous owner installed a second, panel-mounted transponder. I've had to use it twice now. Having the GPS set your squawk code is a great convenience when it works, but when it doesn't, I definitely appreciate having the backup.
What do you mean by "caa"?The consequences of our light g.a. a/c having a transponder failure is not terrible - we continue vfr or maybe have to inconvenience a handful of people who understand equipment failures happen.
For biz a/c and the airlines, the consequences of the only transponder failing are not as tolerable to the people involved. "We can't go because that little box doesn't work?" (I doubt larger a/c can dispatch without a functioning txpdr into rvsm...or caa at all.)
The redundancy provided by the additional expense of several thousand dollars is worthwhile for those flying multimillion dollar a/c....but mostly is not for those in $75,000 a/c.
I have had one fail a couple times in caa and it is really, really nice to just flip that switch and carry on, giving atc only a minimum of angst.

Well if you look back through this...or any thread, there are always acronyms and other abbreviations. The question becomes which do we assume everyone knows and which need spelling out. I assumed wrong, my apologies; 30 lashes accepted and I will try to remember to spell more of them out.
Wouldn't it just be easier to say Class A airspace, rather than confusing the heck out of people with yet another acronym that really isn't necessary?
Because it doesn't just set the squawk code; since it's a GPS, it can sense your ground speed. The CNX-80, when the link is working, will set the SBY and ALT modes depending on a user-settable trigger speed. It can also set your code to 7700 or 1200 with a single key stroke (might take 2, since these functions are accessed through a menu). This only works with certain transponders like the SL-70.How so?
I didn't know what caa meant either and I spend most of my time there.Ok, so I didn't know either what "caa" meant. That's probably because I've never flown in that airspace as a private pilot.
It's not nearly as bad as some of the jargon the computer geeks here use.Jeez, I didn't even come up with the darned acronyms - I read it several times -maybe it was on other aviation boards and figured all knew caa, cba, cca, etc. Please don't make a big deal out of this, I have already apologized.
I don't recall being vilified over a minor gaffe like this since....the Red Board. I sure hope.....
I just figured it had something to do with Canada. I'm going to start doing that, anything I don't understand it must be something to do with Canada

That was my philosophy as well, but as of late, Canada makes more sense to me.
