Transponders are required for all registered aircraft, if they were
manufactured with an electrical system.

I respectfully ask for the FAR where that is written.

http://masl.to/?P28B1534E

FAR 91.215 section (b) paragraph (5)

(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, replying to Mode 3/A interrogations with the code
specified by ATC, or a Mode S capability, replying to Mode 3/A
interrogations with the code specified by ATC and intermode and Mode S
interrogations in accordance with the applicable provisions specified in
TSO C–112, and that aircraft is equipped with automatic pressure
altitude reporting equipment having a Mode C capability that
automatically replies to Mode C interrogations by transmitting pressure
altitude information in 100-foot increments. This requirement applies—

...

(5) All aircraft except any aircraft which was not originally
certificated with an engine-driven electrical system or which has not
subsequently been certified with such a system installed, balloon, or
glider—

I should have added the full paragraph 5, which is actually an exclusion
for airplanes that don't have an electrical system.

"(i) In all airspace of the 48 contiguous states and the District of
Columbia at and above 10,000 feet MSL, excluding the airspace at and below
2,500 feet above the surface; and

(ii) In the airspace from the surface to 10,000 feet MSL within a 10-
nautical-mile radius of any airport listed in appendix D, section 2 of this
part, excluding the airspace below 1,200 feet outside of the lateral
boundaries of the surface area of the airspace designated for that
airport."


The rule is actually as Ron described - Transpoder required in Class A, B,
and C, and all airspace above 10,000' MSL (except below 2,500' AGL), and
within the 30NM Mode C Veils of the Class B airports listed in the
appendix. I think it's all of them, but not sure because why would they
specifically list them if so?



Boy! I'm glad I studied Talmud as a kid!
