Changed
1. AF of 8+ have AV support doubled for purposes of determining support for air operations
(complements fix 18 above)
The basis behind this is that a larger AF would have better service facilities available, and thus be able to service more a/c with same AV than could be handled at a smaller AF (say 4). Doubling it was just a starting point. Also means that a smaller size AV unit might be able support the large AF, while the bigger AV units could be deployed in the front-line areas as is probably the case now.
A more important consideration was that there are a limited number of units with AV in the original scenarios. Suddenly removing the 250 cap might mean a shortage of AV units to cover all the possible AFs, which would impact existing games too much.
If the original removal of the cap had stayed put (rather than been lost and not noticed till now), then this 'doubling' may not have been required, although I feel some sort of 'incremental' value would be warranted for the larger AFs.
