How do Air Units Work?

[ComradeP]

My apologies, I thought you were familiar with those.

There's a certain Air Availability percentage per side which can be seen in the Parameter Data screen. If it's 50%, your units will on average be available every 2 turns provided they're not disrupted or fatigued.

There's an optional Low Visibility Air Effects rule, on by default, which determines by a percentage how many of the aircraft of a certain side can be active during a certain turn out of the available air units. This percentage can also be found in the Parameter Data screen.

As an aside: when I said that there's more variability for the low visibility rule, I meant that it takes longer for the weather to move from one percentage chance to the next and I'm not sure if it scales up to the next given percentage for a certain visibility or if it only increases at the next given visibility.

As in: if it increases when the when going from 8 hexes (25%) to 9 hexes, if the next given value is 50% at 12 hexes.

Variability can vary a lot. In my first State Farm PBEM, visibility is 12. In the second, it's 4.

Edit: here's the description given in the PzC manual, nearly the same manual as the PB manual. I've added some Parameter Data values in the middle.
