groundpointsix said:No where (assuming you copied and pasted all the pertienent regulations because it's almost 1am and I'm too lazy to look for myself) does it say my flight instructor certificate has to have the appropriate category and class rating for the purpose of instrument instruction.
I re-read Mini's post and he actually missed the nugget that really says it.
Here it is:
61.195
(b) Aircraft ratings. A flight instructor may not conduct flight training in any aircraft for which the flight instructor does not hold:
(1) A pilot certificate and flight instructor certificate with the applicable category and class rating; and
(2) If appropriate, a type rating.
And no, this bit is not referring to training for aircraft ratings, which is a popular misconception. The next paragraph (c), that Mini quoted, states in the body of the text, that it only applies to training for ratings and certificates. This paragraph has no such statement. It covers all flight training and is referring to aircraft ratings that the CFI is required to have.
