reported Under certain conditions, radar scan centering in azimuth is unavailable.

[BarTzi]

Currently there are two ways to enter TWS:

1. Using the radar mode PB (PB5).
2. By locking (STT) a target, and then using PB10 (which will put you in TWS AUTO directly).

 

If you choose to use the second method, scan centering in azimuth will not work from this point onwards.

 

This means that TWS AUTO won't follow the target in azimuth, TWS MAN will not react to TDC press, SPOT won't work, and that you won't be able to offset the scan zone when using AZ/EL. It's like it causes the radar to be stuck pointing forwards no matter what.

 

As you can see here, while using TWS AUTO - the AZ/EL page shows the radar scan zone following the target (when in fact, it does not), while the radar display shows the target outside of the radar scan zone (fading).

+1, notices this earlier today. As a workaround, cycling to RWS and back to TWS fixes it.

Reproduce:

1) STT a brick.

2) Press PB10 to enter TWS. This should bring you into TWS AUTO.

-> You enter TWS AUTO, however the B-Sweep will not follow the L&S

I already reported this here: 

You can use the track attached to that thread.

if you have short track replays showing it happen please attach them, we are unable to reproduce currently

Attached!

 

STT, PB10, Crank.

 

Note AZ/EL tracks the group, but the B-Sweep on the RDR ATTK does not.

thanks for the track, I have made a report and asked the team to check the behaviour.
