How long does an amraam rely on F-15 radar?

[tmdgm]

When you fire an amraam, is there any way to tell when an amraam acquires on it's own radar?

[vadIL]

Yep, On you'r left down HUD, 2 timers.. 1'st when missle go pitbull (own radar) second after 1st finished is impact counter

Thanks, I'll have to look for that. You mean on the radar where you lock for BVR?

[vadIL]

The counter on you'r HUD

[TekaTeka]

Both HUD and Radar have the timers.

Regarding typical times for going active TTA, it can be anything from 30'ish secs to 0.

Wonderful, Teka:thumbup:

Very nice Teka! So it appears that you can fire on multiple targets while in TWS? I guess the trick is to not STT a target to be able to fire on multiple targets? Also, if the pre-launch timer is 0 when I pickle my missile it will be pitbull off the rail correct?

 

If I fire the missile in TWS the target will not get a hard lock unless the missile goes active correct?

 

What is the typical range for AMRAAM in LOMAC with the firing jet and the target jet around 450knts 180 deg aspect same altitude, I'm talking about before the pre-launch timer is at 0?

Nice diagram Teka

Thanks for the info. How does it work if you multiple launch in TWS, meaning fire an amraam at primary and then secondary?

In real life, how does F-15 know the time of impact? Is there a two way data link between AMRAAM and F-15?

[S77th-GOYA]

Why would it need one? The F-15 targeting computer should know what flight path a homing AMRAAM will take if it has the position and vector of the target. And it would know the velocity of the AMRAAM throughout its flightpath. I would think the displayed TTA figure is an instantaneous result even though the target may be manuevering and changing the TTA constantly.

Every time target maneuvers the missile maneuvers as well. The speed and distance is constantly changing. Therefore the time to impact changes as well. What if the target turn its tail? Does Time to Impact changes as well? Does F-15 radar have to maintain lock for Time to Impact to be calculating correctly?

[GGTharos]

The AIM-120D is the only AAM that I know of that will feature a two-way datalink.

 

The F-15 fire control radar contails look-up tables for the missile's DLZ and flight times under different launch conditions.

Gotta love GG, he knows to much for his own good, he knows to much, he should change his callsign to Bond tail sign 007, lol with all respect GG, your contribution is awesome. I’m learning lots from you posts. Keep it up. :detective:

 

cheers

So Time to Impact is correct at launch time and only if target does not maneuver until impact?

 

Since I don’t fly F-15 much in Lock On (MiG-29 is better, he, he, he ..), how does Time to Impact work in the game? Is it a cheat?

[GGTharos]

Correct, time to impact is valid at launch in lock on. It does not change with maneuver.

 

I don't really know whether this is true of the real aircraft or not.

[Pilotasso]

I suspect it is not. I suspect its only a conservative estimate. Without 2 way datalink I cant think of a way to tell it exactly except by calculated estimation based on radar contact position, speed and missile expected trajectory. It could be that the missile has gone active before TTA has reached 0 (otherwise you would waste the missile). Same for intercept time.

 

With this in mind I would expect the timer to slow down or speed up if the target changes course. I think this is inevitable. In LOMAC its exact, I think it triggers the missiles radar based on the timer regardless of the range. Similar limitation on other areas like the way all radars behave as AESA once a target had been locked in TWS, i.e they update in real time when they sould only update for each sweep.

[192nd_Erdem]

It relies on the radar until Tharos doesn't think it's undermodelled anymore.

[GGTharos]

Say what's on your mind. No, really. Go ahead. ;)

I thought both the Meteor and the MICA have 2-way data links. Is the 120D even flying in testing yet?

[GGTharos]

That might well be, I haven't looked into either of those much.

The 120D is going through trials IIRC. It's not operational though.

No, MICA does not have two-way datalink. Meteor might - I'm thinking it most likely does, based on the Swedes extensive experience with datalinks.
