Trigger Detecting Air Units

[kaylebd06 0]

How do I have a trigger detect air units? I've only seen forums that show how to ignore air units, like "{isTouchingGround _x} count thisList > 0". What is the opposite of this lol?

{!isTouchingGround _x} count thisList > 0

But isTouchingGround can be unreliable.

this && {((getPosATL _x) select 2) > 3} count thislist > 0

Checks initial activation (blufor present or whatever), then checks if it is above a certain altitude. In this case, three meters. Depending on your needs, this may need to be increased to prevent detecting infantry in taller buildings.
