Haha naturally...that's what I'm trying to do, but there's no point practicing a procedure that doesn't work. 😀
I notice in your video that before the cut transition at 0:30, you were in area track mode, and it kept popping out to INR-A. That's what I was seeing with POINT / INR-P, which seems to cause the laser to shut down. After the cut transition at 0:30, you were in INR mode, and the laser stayed on. So I tried that, but that turned out not to be the key - the mode would stay put, but if I went wings level once I was off angle, the laser would still shut off (L stops flashing). Masking by the outermost weapon pylon, which doesn't get rendered in the TGP display, maybe, leaving one wondering why the heck is it acting like it's getting masked? So taking a cue from your video, I held a little bank to keep showing the target a little belly, and behold! It worked! Then I tried it in POINT mode, and holding a little bank, that worked too! So that seems to be the key to holding lock for a laser maverick until impact, while maintaining separation from a SAM.
