You don't want to NORDO to squawk 7600?


Certainly not continuously, it sets off a very annoying alarm in

terminal
facilities. I'd squawk 7600 for about a minute and then go back to my
assigned discrete code. It avoids that nasty alarm and aids tracking in
enroute facilities. One minute is plenty of time to make ATC aware that
you're NORDO, if they didn't know already, and they're going to consider

you
NORDO until they hear from you.


That's interesting. What do the other controllers in the group think?


From and enroute perspective, I agree with Steven. A 7600 code doesn't set
off an annoying alarm in the ARTCC, but it does flash and brighten the
tarfegt to get the Center controller's visual attention. As a non-discrete
code, over a long haul flight it becomes more labor intensive to track you
on 7600. Sure, we can do it (and do) but it would be easier IMO if you
returned to your discrete code after squawking 7600 for a minute or two.

Chip, ZTL

I see. After a failure that causes you to lose both of your completely
independent transceivers, and your transponder, you're confident of the
continued flawless operation of your other avionics because your other
avionics consist solely of a battery operated Garmin 196.


Sure. There's still a single point of failure on most singles. You may
have multiple radios, transponders, etc... but their all fed from the same
single electrical bus. A battery operated handheld (GPS or COM) has a
good chance of working, especially if you have spare batteries.

Back when I was using the hillbilly mechanics I had numerous failures of
the electrical system (due to their ineptitude at replacing the regulator/OVP
unit).

Well, that's where I was going when I asked "what bizarre failure causes me
to lose both of my completely independent transceivers, and my transponder,
but leaves me fully confident
of the continued flawless operation of my other avionics?" An electrical
failure will affect all of your installed avionics, not just the
transceivers and transponder.

What additional installed avionics do most of us have? Other than the audio panel,
everything connected to my electrical system is a light (well except for pitot heat).

How about opening a sport bottle at 9,000 feet and having it spray water
over a portion of the panel, temporarily shorting out the freshly bathed
avionics?

Some airplanes have navigation radios installed.

I think he was asking what would kill your comm and transponder but not your nav.
likelihood is that it would be a whole electrical system failure, in which case you'd
have to depend on your handheld electronics. You do have spare batteries for them
when you fly, don't you?

If I did for some reason run short on spare batteries, I can tell you that the GPS
would take priority over the handheld comm. Besides, my GPS only uses 4 AA's
where my handheld comm uses 10.

Yep, I carry a whole brick of AA's. Use them for everything from the ANR headsets
to the flashlights.

Not all of them are.
