SLAM TMR changes with aircraft aspect

[skypickle]

In the attached track, I set up a SLAM with the LOW flight profile in TOO mode with the target at WPT 3.  Watch the large circle change size just by changing the aircraft aspect. Is this expected?

Also, the SLAM then becomes crossed out and the track in the HSI disappears . I reselect the target but SLAM remains crossed out. What am I doing wrong?

Here is a better track that shows the TMR changing with the aircraft AOA. Again at some point the SLAM goes from RDY to a crossed out condition for unknown reason.

Watch your speed as that circle contracts and expands.  As your speed is going down (while you're turning) it's contracting because the SLAM is starting at a slower speed so can't travel as far (using more energy to go the same distance because you're giving it less of a boost off the start).  Also (although I don't think it's the thing in this case) if you point your nose off the target, the circle is going to contract because the SLAM is going to have to travel farther/expend extra energy in a turn than if you're heading directly toward the target (that's what I was expecting to see TBH).

And sorry, didn't pay attention to the X'ed out, but that likely means you're within MIN range or due to speed/off boresight you're beyond MAX range.
