A weapon whose projectile is not anti-aircraft cannot fire at anything in the air. The test is on the target’s height, not its kind: an object is in the air once it is placed on the map and at least one terrain level above the ground beneath it. An aircraft in flight, a JumpJet=yes infantry in flight and a vehicle lifted by a flying locomotor are all refused. A hover vehicle never counts as airborne.
The same projectile also limits how steeply the weapon can fire upward. When the firer is not itself airborne and the projectile is not Arcing=yes, a target is out of range if it is at least as high above the firer as it is away horizontally. AA=yes removes that limit.
An object does not return fire at an aircraft that damaged it unless the weapon it would use against that aircraft has an AA=yes projectile. This holds even when the aircraft has landed. Retaliation lists the other conditions.
An AA=yes projectile detonates as soon as it comes within half a cell of its target when that target is an aircraft, landed or not, or a JumpJet=yes infantry in flight.
With AG=no beside it, the weapon is air-only: it fires at no object on the ground. AG says when such a weapon can still be ordered to fire at a map cell. The default pairing, AA=no with AG=yes, is the ground-only mirror.
Automatic target scans also read this setting. A weapon slot whose projectile is AA=yes adds aircraft to the kinds of target the object looks for, unless AV=yes on the same projectile limits the slot to vehicles. What each kind of object considers says when an object’s weapons fill that list. AV has no effect on the firing test.
