I guess my line of thinking is this....
If I have a question regarding regs, I get the regs out and read them to see if I can answer the question myself. The only reason I said to read the regs is because that is the only place to find the right answer in the first place. not to be an ass. Just because a bunch of people on the message board say it is so, doesn't mean it is. I was in the same boat myself during my CFI oral, and I looked up the answer and we talked about it. As a CFI, you CAN give instrument training to a student going for his/her instrument rating. Only 15 hours of the 40 total has to be given by an "authorized" or II.
Had I not been asked this question by the FAA, I wouldn't know the answer myself.
