fixed Trouble with AGM-65D Handoff with TMS Right

[Comrade Doge]

     Hello everyone, I was having trouble with the AGM-65D in the AUTO handoff mode, particularly the re-attempt of handing off after a failed one. I'll start out by saying that it might just be me doing something wrong, it often is, but I will try to explain this situation the best I can.

    The situation is as follows:

1. You gain a POINT track on a moving target with the TGP in AUTO handoff, by TMS Up with SOI on the TGP;
2. The AGM-65D, in PRE mode, attempts a handoff, but fails, as it is out of range. So far so good. WPN page shows the Break Lock mode (crosshairs halved in length);
3. TMS Up again on the TGP page won't command another handoff, so you do TMS Right to trigger the handoff again (DCS F-16 manual, page 171: "TMS right will hand off the lock to the AGM-65 if the target contrast and size meets criteria of missile lock.");
4. "HANDOFF IN PROGRESS" shows on the WPN page again, but the missile doesn't slew to the TGP line of sight, and does not attempt another lock/handoff. It remains stuck in the Break Lock mode. I used a moving target to further show that the AGM-65 doesn't actually attempt another handoff, as the TGP keeps tracking the target, but the AGM-65 seeker does not slew to it, despite the handoff-in-progress message. Even after getting well within range, it shows the same behaviour.

    This would be the issue I am currently facing, in brief, after failing a handoff from the TGP with TMS Up, the AGM-65 will not do any more handoffs with TMS Right on the TGP page, despite the message telling so.

    Curiously, if TMS Down is performed on the WPN page, and the maverick gets out from the Break Lock mode, handoffs work again, that is, until it gets stuck in Break Lock mode once more. While this works, it somewhat makes the AUTO handoff system useless, as you might have to move the SOI to the WPN page just like the MAN handoff method.

    Any enlightment on this confusing matter would be appreciated, and again, might just be me doing things wrong. I tried to take reference from the DCS manuals about the procedure, and this is what I got.

    Notes:

• The missiles were boresighted properly, in a test I even used an air spawned plane to make sure;
• I am using the AGM-65D which supports auto-handoff
• I will attach a video and a trackfile below, where I attempt continous handoffs with TMS Right until in range, which all fail. Observe the AGM-65 seeker not actually slewing to the moving target when commanded to handoff, remaining stuck in the Break Lock mode, while the TGP continues to track it in POINT. Towards the end of the video you can notice I have gotten well within range, and am aligned properly to the Bomb Fall Line, so that the AGM-65 seeker has a clear view, to no avail.

I have asked the team to take a look. 

Seems difficult to hand off on a moving target. 

thanks

Not sure if this is the correct behavior or bug, but when you make a point track with the tgp and it follows the moving target the maverick camera won't follow the target unless the tgp is SOI. So if you want to designate the missile and you make WPN page SOI the missile will stop following the target and get fixed to the last position it was before you switched SOI.

steps i did was : AG mode - set mav to pre in SMS - leave TGP to MAN mode then find target and make point track so it follows the target- make WPN page SOI and press TMS aft to CZ the missile - and then switch SOI between TGP and WPN page to watch the behavior 

 

mav not following point track if tgp is not SOI.trk

Didn't watch the track, what Maverick model are we talking about?

If I remember correctly, the only models we have in DCS for the F-16 are CCD or IR sensor equipped models, and those are fire-and-forget weapons, they should be completely independent of what's going on in the aircraft and track the target autonomously once released. So unless you are firing a laser-guided Maverick, that sure sounds like a bug.
