Transponder

All of that is a real stretch.

Would you pay a professional to put air in your tires?

No. I would pay a professional, though, to inspect and repair my
steering or brakes.

As to a transponder, and its vitial importance to the system (and to my
TCAS when sharing the airspace with VFR aircraft) a transponder's proper
functioning has importance to everyone using the system. Your proper
tire inflation does not.

You put Nitrogen in your tires? Must be fancy tires.


I use a special composition, about 80% nitrogen and 20% oxygen.

When I read a message like this it scares me to think you're sharing IFR
airspace. Hopefully, it's in not in conjested airspace.

I don't see why it should be a big deal. ATC has the capability to
receive multiple idents simultaneously. I would imagine most
controllers can deal with this kind of problem without skipping a beat -
even if you're VFR and not in contact with ATC.



I appreciate (as usual) Tim's comment, however it may be a bit over the
top. After all, we're talking about an IDENT button stuck behind a
faceplate. The OP showed a cautious attitude by posting his question here
in the first place. In the end, ATC will be able to tell you immediately if
your transponder is OK, and if the IDENT is working, inop, or stuck ON.

Improper tire inflation can have a significant adverse impact on the
system and on safey, especially at busy airports such as those in class
B. Improper fueling can too, but I do fuel my own aircraft on occasion
rather than pay a professional.

The issue isn't whether the item in question is of "vital importance"
but whether it is simple or tricky to fix, which relates to the
likelyhood of a non-pro causing problems. It is not unreasonable to
expect that a stuck ident button is simple to fix. It is also not
unreasonable to expect that it could be tricky to fix. Therefore the
question is perfectly reasonable, and replies should be helpful rather
than insulting.

My take is that once a transponder acts up like that, it's time to have it
bench checked. With a light aircraft panel mount, the owner could certainly
remove the unit and take it to the avionics shop.

In military aviation or the airlines, it would be a log book write up and the
professional mechs would probably remove it and take it to the avionics shop.

My King KT-76A transponder has a stuck "Ident" button.
It stuck when activated for ATC on the last flight and the button appears to
have colapsed sideways underneath the cover panel. It is no longer visible
in the opening now. ATC says the unit indicates an "Indent" signal
presently.
Does this require an avionics shop to repair or could it be a simple matter
such as removing the unit, then remove the cover plate and look for a
colapsed return spring?
Thanks,
Tom


Can you still see the button inside the panel?

The plastic button usually just pushes on the switch below it, if you
pushed to hard the button sometimes gets lodged underneath the panel. If
that is the case just get a paper clip, open it up and use the end to
see if you can realign the button so that it pops back through the hole
in the plastic plate on the transponder. Then don't push so hard the
next time you ident.

If you have to open up the unit best to have the avionics tech do it
unless you are familiar enough with the unit to try it yourself.

The FAA recommends a maximum of 5% Oxygen.

True, but that reccomendation is for the gasses outside the tire, the
ones in contact with the treads. It does not apply to the gasses
inside, which are enclosed by an FAA approved tube.

Isn't that mixture also known as "air"?

Doesn't removing the transponder from the tray disconnect it from the
static system and thus require a re certification under 91.411(2)
before it can be used IFR in controlled airspace?
