Question for jet pilots

Air radar, it lists it as a passive permanent upgrade, yet it needs to be equipped to work, or so it seems.

Below the radar, it seems that I have to get stupidly low to the ground in order for it to work, has anyone else experienced this?

My current setup as of late has been as follows for jets

Stealth
Air Radar
Fire Extinguisher (Dodging missiles hasn't been too much an issue rather than the ambushed done by hidden AA tanks and the occasional lucky cannon strafe from helicopter and such.

I run
Air Radar
IRFlares
Rocket Pods

I'm not sure what you mean by stupidly low, but i find it seems to work just above the tree line

How many strafes does it usually take to deck a mobile AA? I swear I unloaded a full salvo of rockets and even laid into one with my cannons and I could kill the bastard....twice.

I try to make my turn arounds as short as possible, but I seem to have trouble with them sometimes. Engineer helping them perhaps?

He could have possibly had reactive armor, I'm pretty sure it just takes one salvo if you hit it with all your rockets.
