AMRAAM guidance issue

[JTFF - Raph]

Hi there,

 

Since the update, loft seems better, but I founded an issue on the guidance.

 

Note that the first AMRAAM is lauched at 56nm with a low aspect, high altitude and high closure rate.

 

I'm launching this missile way before my HUD indicates max range because DLZ are not implemented (cf this post https://forums.eagle.ru/showthread.php?p=4265751)

 

It seems like the missile is not updated and dumb in the last seconds.

 

Missile was supported continuously during the F-POLE and goes HPRF when I still have a SAM lock on the hostile. As you can see, the AI will not defend or do anything when a missile is not gonna be dangerous. This missile is considered as "no factor".

 

Second launch is inside the "max range" and reach the hostile.

 

Everything in this one:

Track AMRAAM.trk

Cheers,

 

Raph.

The missile ran out of batteries. They only last for 80 seconds. The missile ran out at 5:32:00 Zulu. You can see that its control surfaces lock and the missiles performs no more steering commands. The seeker is no longer pinging which is why the AI ignored it.

Looking at the Tacview, your first AMRAAM is in flight for over 2 minutes. If I recall correctly the battery life is on the order of 100 seconds, after which it goes dumb by default. At first glance it's a bit weird that it seems to keep pitching in the same direction after that time; perhaps ED is simulating the control fins being stuck in the same position once the battery runs out. Battery life being a major limiting factor in the AMRAAM's range is realistic.

 

 

By comparison, your second AMRAAM is in flight for ~50 seconds.

So there is a problem somewhere else, an AMRAAM not able to reach a 55nm launch considering that DLZ are not implemented. Before this update we where capable to get a real max range over 60 nm

[TLTeo]

It was possible by flying at higher Mach and altitude, shortening the time of flight to reach that distance. As far as I know, battery life has not changed.

That's exactly the question I was asking myself, I was discussing with friends on an "other sim". I don't want to name it because I'll get censored or banned ^^. And we get better performances on this one... I gonna ask it to BN.

AIM120 has battery life time of 80 seconds. And in "the other sim", it is the same of 80 seconds.
