Cubdrick,
You said one needs to be a lawyer to understand the FAA regs. You are correct. I've said there should be questions about bankruptcy and labor law on the ATP written, if you do this for a living you'll have to deal with both.
I can't see anything about putting a CLT restriction on the CFI in the guidance from the FAA. The PTS does say the aircraft used has to be able to perform all the tasks for the checkride. Maybe there's something buried in the Mil to Civilian conversion.
