Wind broadcast on ATIS, AWOS, and ASOS is magnetic.

Wow that's what I thought too. *But the AIM 7-1-12 most definitely is
saying that it is in true (or is that a typo?). *Of course the

brought it up before I have a question about it on my written though.
That would have been a silly question to miss.

I don't see the word "true" anywhere in AIM 7-1-12. *The NOTE in AIM
7-1-12.d.3. states, "Wind direction broadcast over FAA radios is in
reference to magnetic north."

Um, sorry. I think you are right kinda. The figure later in that AIM
says:

AIM 7-1-12 d5 Fig 7-1-8 (METAR): "WIND DIRECTION AND SPEED. Direction
in
tens of degrees from true north (first three digits) ..."
