Actually, the Business Case (although not all of it) would form a large part of the ACP to the CAA especially for an ATSU that as yet doesn’t exist. Doncaster Sheffield is a prime example of this, I remember reading it at great length.
Southend’s CAS ACP was different as they already had a few new commercial flights, the passenger numbers was not quite yet there for CAS but the airlines wanted the protection of CAS before increasing their movements which they did very soon after the implementation.
As already said before, the magic number of passengers required before CAS will be given is not known and it seems to rely heavily on what the DfT are given by way of ACP which ultimately gets its facts and figures from some kind of Business Case/Model from the Sponsor.
