SLF 3
You're not wrong. However, aeronautical emergency planning on airfields is laid out in black & white by the CAA - at least the minimum responses are. An individual aerodrome licensee may then apply local issues as deemed fit.
Furthermore, whilst most emergecies end up as
"non-events" - fortunately, those that do not, tend to be entirely different in most respects and you therefore cannot be too prescriptive. You do however, have to have the basics clearly defined.
By the way V1 and ATCO's in my experience tend to stick with the book.
