Before a combat flight, I usually set my chaff/flare program to "semi" and set it to release 5 chaff and 5 flares. This way, whenever someone locks me or launches at me, I can authorise the release and the plane will drop 5 chaff in semi mode.
This works well against Fox 3's and Fox 1's since the plane gets RWR warning. However for Fox 2's you need to rely on your intuition on where to flare. And, crucially, you want to only release flares but not chaff. However if you hit manual release on your CMS, it will release 5 chaff and 5 flares according to the program set.
Is there a way to somehow set it up to be able to conditionally release only chaff or only flares or both depending on the situation? What's the standard setup for the countermeasures when flying against Fox-3 and Fox-2-capable aircrafts?
