Right, it is obvious that congress got the definition from the AMA but I can't figure out the source. I was curious since the only source I have found was in the AMA FPV doc 550 which would imply congressional awareness and approval. Thus, negating the FAA stance on VLOS. And you still seem awfully distraught to me.
