"Air Availability"

[carl11]

Okay, so two different air avails that can be set. The scenario availability is where air units that have been added to the scenario can be set to not available until a certain point. This is under Scenario - Air Support. There, you can set each air unit's actual strength through Increase/Decrease. Set Availability through that button, which allows you to set when an air unit becomes available.

For the PDT, Korsun should have a program in its main folder - pcparam.exe. Run that, open the PDT file used by the scenario (maybe just one for all scenarios?) and you can see there what value is the setting. Actually, even easier, in the game, press F4 and the values are displayed, no need to use the editor!

Bingo, you're the man,   I found the availability % in the pcparam.exe, thank you Ricky!
