[REPORTED] ACM vertical scan: radar elevation stuck

[Bonzo0181]

When using the vertical scan mode (DGFT-aft & TMS down), the radar elevation is stuck at the bottom of its range.

 

 

 

Instead of sweeping from -10* to +60* elevation (or whatever it should be), it just looks down at gimbal limit, while being centered laterally. This can be seen on de MFD by looking at the elev. & azimuth carets.

 

 

A quick test reveals that the radar is indeed looking down (see track). It will only pick up a target once it is low off the nose.

 

 

 

Tested with hot and cold starts, same results.

 

 

 

It seems to be a similar issue as a bug I reported earlier, involving ACM bore (which has been resolved since). https://forums.eagle.ru/showpost.php?p=4196577&postcount=4
