Opportunity fire with AAA

I think I my have been misunderstanding how the filters work and still no to sure.

First the y key controls the range of the main weapon (slot 1). Should other weapons also fire if they have the range?

The op-fire filter can alter this fire range allowing it to be refined for four different classes. Because air units do not fall within these four classes then they simple use the Y key setting if it's the main weapon.
