I don't think you can "harm" the avionics by removing power, by CB or
otherwise.


I did not intend to suggest that a sudden loss of electrical power would
suddenly render the components forever dead.

It is a whole lot of money to be playing games with.


True, but your safety may depend on your knowledge of just how those
expensive avionics will respond. For instance, in case of smoke it is my
intention to secure all electrical power. I should know what happens when I
do this, and then restore power.

Pulling circuit breakers when there is smoke is prudent. Pulling them
for training is not.

So, when you pull it "prudently", it is your first time? And, you'll wait
until you have a real emergency to find out what else you'll have to deal
with?
I thought that we trained so that in an emergency it won't be your first
time.

You don't have to check, just read the transponder requirements in Part 91.

91.215 has one of those "Unless otherwise authorized or directed by
ATC" clauses. I've had conversations like this more than once:

"New York, I'm doing some avionics testing, and would like to shut
down my transponder for a while".

"Approved as requested".

That's all it takes.

I pull breakers all the time on students. Instrument breakers. Gear
breakers. A/P breakers.

You'd be amazed how many times I pull a gear breaker and watch a
student not notice that they didn't get three green lights. Sometimes
they even mumble "three green" out of habit.

I don't remember seeing any specific error message. I hate to admit it, but
I don't remember looking for the satellites page. The pretty little map was
just frozen on the last place it knew it was (which was right under the St.
Louis class B shelf. :-D).
Ah, well. That DA-40 has now been sold & our FBO has a shiny used Warrior...

Or put a guard on it, can be as simple as a metal or
plastic wall.

Was the GPS totally dead or just not locked on the
satellites?

My experience with Garmin stuff is limited to the 530. I would never
pull the CB for it without first turning the unit off.

My GNS530 is connected to a Avionic Master Switch. It is fine to turn
off the AMS without turn off the 530. It won't hurt anything. GN
S530 is a solid state computer. There is no hard drive inside that is
needed to be shutdown and park the reading heads.

I didn't glean that he wanted to ask. Depends where he is in SoCal
airspace whether they would say yes.

Not necessarily so.

If you own the airplance with the G1000 and want to practice pulling CBs
for complex electronic gear, have at it.

If you are comfortable doing it that way, have at it.
