Cycling A/A missiles

[exnihilodub]

Hi. I was wondering how do you switch between a2a missiles if you have both 24j and 74 loaded?

If it's the IR fast select button on the left side, how do you know which missile you have selected right then?

If I'm not supposed to carry two types of missiles, why does the viggen have CAP (6 AAM) as a preset loadout?

 

thanks for your time answering my questions and I wish you all a great night

There's a button on the left console for cycling missiles, but it's broken, because beta.

 

I guess the CAP payload is more a "because we can" loadout, rather than the historical one.
