APKWS fail to track

[Pyrocumulous]

I am experiencing that APKWS rockets will sometimes fail to track, which seems to happen after several rockets have been launched successfully, and then all subsequent rockets will fail to track. Attached is a track of this occurring. I have additional tracks showing the same thing if that is useful. Launching of rockets begins at 05:20.The TPOD worked to guide in 6 LJDAMs and then continued to work for the first rocket, before something stopped working. I tried cycling TPOD through standby, changing code and resetting, as well as using D&M or EYES mode. None of which remedied the problem. The track is flown with 1688 set as the APKWS code, but I had the same issue yesterday with 1777 code. It's almost like the APKWS code is changing mid-flight, but if it did, it was not indicated on the in-flight kneeboard.

Pilot error is always a possibility!

(note: looking back, I have not noticed this behavior when I wasn't using GBU-54 LJDAMs; however, LJDAMS and APKWS are my favorite weapons in the AV-8B so it doesn't mean all that much)

Upon further experimentation, I think the issue is low air speed at launch. Not sure if that's correct behavior or not, but it seems that the rockets do not track if fired below some air speed regardless of dive angle. Not sure what that air speed is, since I'm always in A/G mode, but it feels like it's somewhere around 300 knots.

Just tested it, had no issues whatever the speed of launch, would you have a track ?

There's a track linked in the first post. I didn't conclusively link it to airspeed, but it did appear to resolve the issue.
