Gattling Posted July 23, 2020 Posted July 23, 2020 I am encountering this problem of Radar going to STT mode with single TMS UP command. I guess it should do that with twice TMS UP only. Anybody with similar problem or troubleshoot? Thanks.
Frederf Posted July 23, 2020 Posted July 23, 2020 (edited) There are conditions at which SAM will automatically transition to STT like jamming or fade without input from the pilot. Otherwise there are conditions where the search portion of SAM are temporarily suspended which will look a lot like STT (close range, coast, RAID). You should know this temporary condition because the FCR cursors are displaced above the bug (as they always are in AUTO SAM). What were the conditions of the track, was the target very close, jamming, near the vertical or horizontal limits? Edited July 23, 2020 by Frederf

I have tried it under various own and target conditions and at multiple ranges but the result is always same. it directly goes into STT mode as if getting a twice TMS Up command. The FCR remains in STT and with no obviously no cursor and narrow Az. Similarly a single TMS Aft rejects the target altogether as if getting a twice TMS Aft command.

Does your "narrow AZ" look like this? If so its not in STT, it is in SAM mode. Eagle Enthusiast, Fresco Fan. Patiently waiting for the F-15E. Clicky F-15C when?

Gattling Posted July 24, 2020 Author Posted July 24, 2020 Does your "narrow AZ" look like this? If so its not in STT, it is in SAM mode. Yes. Its pretty much same. But the cursor is unable to move and I cant target multiple contacts without that. I guess, single TMS Up should not narrow down the Az and lock the cursor. Is it early release limitation or some input problem at my end?

Even though it doesn't work as it is supposed to, that is indeed SAM mode on the picture. If you press TMS up again you'll enter STT and the blue azimuth lines disappear. -Col.

Etirion Posted July 24, 2020 Posted July 24, 2020 (edited) SAM mode is exactly for what it says, situational awareness. It'll still scan for radar hits in the narrow AZ instead of only displaying the targeted aircraft as it would in STT. If you want to target multiple aircraft you need to use TWS. To explain this a bit further: STT focuses the radar energy solely on the target, with SAM mode it will focus the energy shortly on the target then do a sweep and focus back on the target and then repeat that, you can observe this with the radar position indicators (the blue bars, whats the actual term for these?). STT and SAM are modes within RWS. TWS is an entirely different radar mode, as the name says it builds target tracks where it does predictive math based on the last known position, velocity and heading, but keep in mind that it will only get new updated and accurate information when the radar actually sweeps over the contact again and gets a return.

Thanks a lot for the deliberation. So, what i understand up till now; Early release Viper is limited to target/lock and subsequently do a valid BVR launch only one contact in SAM mode instead of 4 I guess in actual. Correct me if anything wrong in this statement. Goalposts; i think, the term for the blue Az bars.

I'm not sure if SAM mode will be able to launch on multiple contacts, for now just do it with TWS as explained here by wags: Didn't mean the goalposts, Azimuth and Elevation Carets as per the manual is the name, the little blue guys showing the radar sweeping.
dundun92 Posted July 24, 2020 Posted July 24, 2020 SAM should eventually be able to lock 2 contacts, but thats not been added yet. Eagle Enthusiast, Fresco Fan. Patiently waiting for the F-15E.

Frederf Posted July 24, 2020 Posted July 24, 2020 I don't know if the v5 radar can only do TTS (2) or if it can do MTS (4). In any case you can guide AIM-120s onto as many system tracks as that mode is able to support. If you still have blue vertical azimuth bars you ain't in STT. SAM has two modes: AUTO and MANUAL. AUTO SAM is where the cursor is "stuck" to the bug (actually it should be displaced above it) and the scan zone is centered on the bug in az and el. MANUAL SAM is where the cursor (and scan zone) is free to roam unstuck from the bug. The size of the scan zone (or if it exists at all) in both AUTO and MANUAL SAM is dependent on the requirements of maintaining the primary and secondary track(s). It's possible for the scan zone to vanish entirely (temporarily) if the radar needs to dedicate resources to the tracks. When search is suspended one clue that you're not in STT is that the cursor is still visible.
CarbonFox Posted August 15, 2020 Posted August 15, 2020 (edited) TMS Up in TWS does not work at all for me. Seems to be a major problem in MP servers as I have less of a problem locking up aircraft offline. Not sure if this is due to jamming from other aircraft as I did observe radar contacts jumping positions.
