My undertanding is currently you have a short window to flare a R-73/Magic 2 before the seekers occular closes the FOV and focuses purely on your engine.
If it is focusing straight off the rail the only way to defeat it is through angling your airframe so your flares intersect the FOV of the missile which is risky and harder to do when you are already defending. With ranges and flights times (people generally dont launch R-73 or Magic 2s from more than 2.5km) They are going to be significantly more lethal than what we currently have in game.
in a headon?
because that seems a bit far in any other aspect
in a rear-aspect shot i dont go further out than 1.5km, if the target is running away, to make sure the missile hits
Usually the magic 2 has the range to hit targets at up to 2-2.5km against low supersonic jets with an aircraft launch at the same speed at ground level.
It will be slightly lower for faster target/slower launch vehicle, and higher at higher altitude .
At 2.5km if the enemy doesn’t perform maneuver you’ll reach it just fine but if he starts maneuvering the magic 2 can lose too much speed
