Do Air Units get replacements?

[von Waldenburg]

If I'm not mistaken the Low replacement rates in bulge may have something to do with the few planes replaced. If the recovery is 1% or even 2% you would need to lose roughly 40-50% of an asset's strength to get good chances of seeing replacements coming in somewhat fluidly. It depends on the strenght lost previously in combat.

The way I see it is: as there's no expecific explanations for fatigue, disruption, etc for air units in the rulebook and considering what I've seen in command reports over the years I guess they work in many ways as a normal unit. So I asume in a 3 night turn scheme they would be able to recover a lot of fatigue like any other unit.
