Hello Sam Hoskins, You wrote:
1) "Without looking at the regs, I seem to recall that if the aircraft is
equipped with an operating transponder, it must be turned on."
That is correct. Here is what 14 CFR 91.215 (c) says:
"(c) Transponder-on operation. While in the airspace as specified in
paragraph (b) of this section or in all controlled airspace, each person
operating an aircraft equipped with an operable ATC transponder maintained
in accordance with 91.413 of this part shall operate the transponder,
including Mode C equipment if installed, and shall reply on the appropriate
code or as assigned by ATC."
2) "My simple minded solution would to pull the transponder and stuff it
into a flight
bag. You could even apply a sticker that says "INOP". Fly to the shop, then
install it for the test."
That would be a violation of 14 CFR 91.215 which says, in part:
"(b) All airspace. Unless otherwise authorized or directed by ATC, no person
may operate an aircraft in the airspace described in paragraphs (b)(1)
through (b)(5) of this section, unless that aircraft is equipped with an
operable coded radar beacon transponder having either Mode 3/A 4096 code
capability,.............."
91.215 goes on to provide some exceptions to the above requirement such as
aircraft originally certified with no electrical system and getting
permission from ATC to operate with no transponder. What you describe is not
one of the exceptions.

1) "Being able to do my own pitot-static check will also get me a long way
to being able to discuss with some authority."
A) There is no regulatory requirement for a pitot system check, but you may
gain some confidence in the accuracy of your airspeed indicator by
performing one.
B) The static pressure system check performed in order to meet the
requirements of 14 CFR 91.411 quoted here:
"Altimeter system and altitude reporting equipment tests and inspections.
(a) No person may operate an airplane, or helicopter, in controlled airspace
under IFR unless-
(1) Within the preceding 24 calendar months, each static pressure system,
each altimeter instrument, and each automatic pressure altitude reporting
system has been tested and inspected and found to comply with appendices E
and F of part 43 of this chapter;"
Must be performed in accordance with the portion of 14 CFR 91.411 quoted
here:
"(b) The tests required by paragraph (a) of this section must be conducted
by-
(1) The manufacturer of the airplane, or helicopter, on which the tests and
inspections are to be performed;
(2) A certificated repair station properly equipped to perform those
functions and holding-
(i) An instrument rating, Class I;
(ii) A limited instrument rating appropriate to the make and model of
appliance to be tested;
(iii) A limited rating appropriate to the test to be performed;
(iv) An airframe rating appropriate to the airplane, or helicopter, to be
tested; or
(3) A certificated mechanic with an airframe rating (static pressure system
tests and inspections only)."
So only if you hold one of the qualifications listed above, would you be
able to perform the regulatory requirement of the static pressure system
tests. But otherwise, as you point out, performing the test yourself could
help you in your discussions. The equipment and parameters to perform the
test are described in 14 CFR Appendix E to Part 43 (a).
2) "Being able to calibrate my BMA EFIS ahead of time will be a giant step
in the right
direction."
Good idea.
3) "I will report back and detail my experience."
I would appreciate that -- thank you.

A discussion is already underway. What is most important to me is to
know the facts. You cannot argue with "experts" if you don't know the
facts. Being able to do my own pitot-static check will also get me a
long way to being able to discuss with some authority. Being able to
calibrate my BMA EFIS ahead of time will be a giant step in the right
direction.
Thanks to all of you for this invaluable help! I will report back and
detail my experience.
