Doug Posted June 12, 2005 Posted June 12, 2005 Hello ! We know that the AIM-120C can be forget when TTA=0. Is it better to keep the lock ? I don't know if the F-15C continue to help the AIM-120C next TTA=0 ... Is it totally independant or can it receive the support of the F-15C's radar ? To be short : Is it useful to keep the lock next TTA=0 ? It can be interesting to avoid FF. Sorry for my poor engish. :( I hope you have understand me. LOTATC .NET // LOVICA .NET // 3rd Wing

I think the exact answer is probably classified, but I wouldn't be surprise if the missile used a combination of homing and datalink to ensure the correct target was hit. In LOMAC, unfortuantely, this is not so. [sIGPIC][/sIGPIC] Reminder: SAM = Speed Bump :D I used to play flight sims like you, but then I took a slammer to the knee - Yoda
britgliderpilot Posted June 12, 2005 Posted June 12, 2005 As I understand it, once the AMRAAM has gone active then it doesn't receive any more information from the launch aircraft. I don't think it can even home on the launch aircraft's emissions - it only has a datalink control, which isn't quite accurate enough. In any case, it would seem that the ARH seeker performance in Lomac is slightly better than it should be anyway. http://img.photobucket.com/albums/v121/britgliderpilot/BS2Britgliderpilot-1.jpg

In any case, it would seem that the ARH seeker performance in Lomac is slightly better than it should be anyway. Not 'better' ... just wrong. It can still receive datalink when homing (the antenna's at the rear of the missile for this reason, and for SARH is also helps determine range and closure) , and if you are STT on the target, the data will be very accurate: Position and vector are updated constantly. The missile COULD then use this additional info to better select its target in the world of ECM, and it -is- possible to guide purely on datalink, but as you said, the Pk goes WAAAAAAAAAAY down in such a situation. That's just my 2 cents though, I don't know wether it does use the DL ornot - my guess is yes, due to some things that I've read that indicate that missiles often use a mixed approach to guidance in order to optimize their trajectories better nad to defeat ECM.

Raploc Posted June 12, 2005 Posted June 12, 2005 GGtharos what do you mean with "Not 'better' ... just wrong" Greetz Raploc
GGTharos Posted June 12, 2005 Posted June 12, 2005 It seems to model a search patter which is not adapted to the firing mode and the search sweep is too ambitious (it searches way too much space, way too fast - IMHO) [sIGPIC][/sIGPIC] Reminder: SAM = Speed Bump :D I used to play flight sims like you, but then I took a slammer to the knee - Yoda
D-Scythe Posted June 12, 2005 Posted June 12, 2005 In any case, it would seem that the ARH seeker performance in Lomac is slightly better than it should be anyway. How did you come to that conclusion? Some info to back this up would be nice. And GG, just wondering, is it possible for the AIM-120 to use info provided from the datalink even after it turns on its active radar seeker, so long as the launch aircraft is still providing the data? I'm guessing then it might provide better performance against chaff this way, but that's just me.

Doug Posted June 13, 2005 Author Posted June 13, 2005 OK. In the manual page 138, I have read : "The data link is used when there is a necessity to correct the missile’s flight trajectory during the mid-flight leg. An active radar seeker, which provides fully independent missile guidance after a safe target lock, turns on the radar and uses high and medium pulse repetitions to detect and track the target." So we have our answer. :D Shame on me. (RTFM :p) Thanks all ;) LOTATC .NET // LOVICA .NET // 3rd Wing

So, unless you have access to some classified stuff, the RTFM answer is completely out of place here ;). Cheers, Asterix
Raploc Posted June 14, 2005 Posted June 14, 2005 Asterix28573 I think Doug asked a question about the game, not RL. So his last post is the answer to his own question. He said RTFM to himself Greetz Raploc
Asterix28573 Posted June 14, 2005 Posted June 14, 2005 Ooooops! Then now I answer myself with a RRTFFPA (Re-Read The F*** First Post Again) :D :D.

Doug Posted June 14, 2005 Author Posted June 14, 2005 Well, we are in LockOn's forum. No ? ;) So me ask concerned Lockon of course ;) LOTATC .NET // LOVICA .NET // 3rd Wing
Asterix28573 Posted June 14, 2005 Posted June 14, 2005 Well, we are in LockOn's forum. No ? ;) So me ask concerned Lockon of course ;) Yep, sure. But as the discussion soonly turned to RL behaviour I completely oublied the initial purpose of the thread :). Anyway, your initial question was also interesting. I have sometimes also wondered myself if keeping the lock after the missile going active helped in any way or not. Best regards, Asterix
firesoldier845 Posted June 15, 2005 Posted June 15, 2005 I thing I wanted to ask about 120C is I been having all sorts of issues online with crazy kills. While online I locked up an enemy WVR maybe 10 miles away and he just shot down one of my teamates. I fired 1 AIM-120C and waited, I saw him make some evasive moves and thought the missile would have hit but must have missed so I fired off 2 more and waited. Again he made some more aggressive moves so I fired off a 4th missile. The entire time I had him locked up STT diving on him. I saw him explode shortly after the 4th missile I fired. He typed "good kill" and I turned away and headed for home. It even said on the screen I killed RED team. I had him locked the entire time and never locked up any other planes. About two min later server message says I killed a BLUE team member-friendly kill. 30 secs or so later another friendly kill!! So 4 missiles fired at a single enemy plane in STT and I wind up hitting him and downing 2 friendlies. Just crazy. I don't know what I did wrong, but definitley AIM-120C seems like it has a mind of it's own. Maybe the friendlies were just in the wrong place at the wrong time but it's weird - I never even locked them up or nothing.
