Good luck, there ain’t one. Here is my futile attempt to add one (there are also a bunch of suggestions filed for this somewhere).
The problem is that the radar scan zone azimuth control is an axis, but is not configured the best way.
The axis is not the position of the scan zone in azimuth, but the speed of movement of that zone. So if you have relative control on and quickly tap and release to move it right, it will start moving right at a constant speed, even though you are no longer pressing the key, because the axis controls the speed of that movement, and not the position of the scan zone.
This means you have to turn off relative control. But now the “center axis” (or whatever it is called) does not do anything useful, because the axis it centers is the speed axis, which already is centered when you are not pressing anything (basically, it does nothing).
On top of lack of centering, you now also can’t control the speed at which you move the scan zone. Moreover, these issue also apply to scan zone (manual) elevation controls.
There are workarounds on some planes for centering. If you have an IRST, you can quickly switch to IRST and back to Radar, this will center the scan zone (might not work on all IRST equipped planes, I have tried most, but not all).
You might be able to reset the scan zone by switching to different modes (PD, PDV), or by switching in and out of TWS. I don’t remember if this works, as I have all the radar axis controls on manual.
But as you can see, these are all crutches and we really need just a fix. Ideally, NOT a keybind to center the scan zone, but just making the axis control the position, instead of velocity.
I know you are a forum mod and not a tech mod, but if the power to forward this bug/suggestion, I would love for you to wield it, among many others (or maybe message some tech modes if possible). I can update the bug report if need be.
No, we don’t have the ability to turn off seeker slaving. Therefore, if you are about to launch an IR missile, like Magic, you need to not be locking anyone or not be in TWS, then the radar has no target “track” selected so it won’t slave your missile.
Ideally, turn off your radar completely whenever you are not using it. This will both help you avoid Magics being accidentally slaved to something random and not reveal your presence to the enemy on their RWR.
Although, If the enemy is flaring and knows about you already, you could lock them up. That way, your Magic will be slaved onto them, but will not follow after each flare, so you can launch at the actual target without the hassle of having to relock your Magic onto them (this will not help it ignore flares after launch, only before launch).
