I'm not real sure if anyone as suggested this or not but I was kinda thinking of a Helicopter mode,  where you could patrol in a chopper.  The call outs could be anything but it puts you in kinda of a commander setting where you could give ground patrol info on where the suspect is (by point and click on map) or where to setup road blocks.  Maybe a missing persons in the woods and you could work with park rangers or a highway patrol where you can spot traffic collisions and call it in,  assisting on swat raids by dropping off fast ropers. I don't know the sky is the limit( pun intended) I just though it would bring in some of the support roles with flying and something different to the game mode.

I would like to see this. Instead of calling for air support you can be the air support. As you said as well, missing people would be fun to have to search for them. I like the idea of Helicopter patrols.
