Just a note about the AMRAAM.

So after looking in the lua with data for the AMRAAM, i noticed in the seeker section of the code this:

delay                        = 1.5,

I looked at some tacviews from dedicated missile testing, and noticed the difference from when I got in seeker range (8nm/15km), and when I got the missile warning was just over 1.5 sec (in the tests I was waiting for missile active and knew it was coming, so I reacted very quickly). So this seems to explain some of the reports of AMRAAMs at very high altitudes and speeds giving a warning about 4nm or less from the target, while at lower altitudes (and consequently slower speeds) they gave warnings much closer to 8nm (closer to 6-7nm). Just thought Id share this finding.

It that a delay for seeker activation after launch or for the RWR to respond? The missile engages its radar about 7nm away from the target in-game, where it should start search about 13nm (the range is dynamic of course, but much longer than what we have), and the WRs themselves seem to have some sort of delay in reporting the missile.

 

At high speed and altitude, with a huge closure that missile won't leave a lot of room for maneuvering.

For sure it affects the RWR delay. I may try cranking it up to some high value and seeing if it stops it from guiding.

Just make a mission where you get engaged by an Aim-120 and flare once you get the launch warning. Then you will see on tacview that the Aim-120 maneuvers way before you deploy the flare. There is certainly a RWR-delay.

So I did a test and this definitely isnt just RWR delay thats affected. The seeker acquisition itself is delayed, and the RWR warning appears to be instantaneous (or at least not linked to this lua value). Heres the tacview. I edited the value to 10 sec. Note the exact 10sec delay from launch to guidance (when it made the turn towards the flanker):

Maybe this value is the delay for the safety maneuver, where the missile will just fly straight without guiding to not hit the carrier.

Not sure why this was moved to the bug section, I'm pretty sure this is intended behavior?
