Summary of Change. Volume 3, Chapter 26, Section 2, Regulatory Sources
of Aviation Weather Information and Aviation Weather Information Systems – Parts
Paragraphs 3-2073, and 3-2075 through 3-2077
incorporate new information. In October of 2012, The Air Transportation
Division (AFS-200) published significant updates to guidance related to the
regulatory requirements for aviation weather information and OpSpec/MSpec A010.
