[CORRECT AS IS] Can’t change radar range by cursor.

[Wicked.-]

While in RWS and TWS I was unable to scale out the radar range by moving the cursor up. Neither myself nor a friend I was flying with were able to do it.

[unknown]

Works for me in RWS not in TWS, SP here.

Already documented that you can’t bump the range in TWS.

I guess I didn't look hard enough! Roger that!

Hi!

 

Already documented that you can’t bump the range in TWS.

 

I don't know on what document you have seen this (?) ...

 

For F-16C BLK 40/42 & 50/52 (APG68 radar), in TWS, range scales are changed as in RWS.

But ... the range scale will not decrease if the TOI cannot be displayed on the lower range scale.

The range scale will automatically decrement when the TOI is at a range less than 45% of the range scale, and when the ACQ cursor is less than 5% of the range scale.

Note also that the TOI will force an auto range scale increase when its range approaches the maximum range of the currently displayed range scale.

 

That is how the system is designed and how it works on the real stuff.

 

Regards.

 

 

Merry Xmas to everyone!

Dee Jay, by HAF document TWS range bumping is explicitly said not allowed. But of course this document is for a different, older version. I don't know if this is different for APG-68v5 of BLK50 ~2007. If you have better info you should share it with devs.

[Dee-Jay]

That is basically what I am doing (more or less) ;) ... it is not something that we can't found elsewhere on other sim". But I won't send such documents for obvious reasons.

 

Dee Jay, by HAF document

Not the -1 right? But the 3-4 correct?

(I don't refer to GR docs as DCS-F16 is not HAF version)

What I was referring to when using the cursor to scale out the radar range was simply that. Using the cursor to increase my scanning distance instead of the MFD OSB’s. I did not have any targets locked at the time. Am I not able to do this? Even when in NAV mode with the FCR page up?

[Dee-Jay]

to increase my scanning distance

Maybe you already know that, but it doesn't change anything to "scaning"distance. radar power/gain remains the same. It only act on display.

DCS has already decided that TWS doesn't have that feature. Either they don't know what you are saying or they're not allowing themselves to know it. I think a private message from you or something with proper knowledge would be the only way.

[Dee-Jay]

Well ... if [CORRECT AS IS], then it is [CORRECT AS IS]. No big deal. There are other more "critical" things on other aspects for the time being.

[Wicked.-]

This I did not know... I could have sworn I've used it like that in the past, both with the other Viper sim and DCS. No worries. If it's correct, then it's correct.

Radar Scale - Automatic Change

 

I know this has been discussed somewhere, but I can't find it, so I figure I'd ask.

 

Under what conditions does the radar scale automatically change with respect to the current range of a locked target? I know I have seen this behavior sometimes, and not others. I know it might be different under different situations; can someone confirm or edit the below statements:

 

In STT lock mode:

When the target closes to <45% of the current range scale, the range scale automatically decrements. For example: radar scale at 80nm, target is locked in STT and is out at 60nm. When it closes to under 36nm, radar range scale (and HUD Launch Zone scale) decrement to 40nm. I might have read somewhere that the radar cursor must also be in the lower 5% of the FCR, but not sure if that is true.

 

In SAM lock Mode:

Does the above take place or is it STT only behavior?

 

In TWS mode with a bugged target:

Does the above behavior also take place with a bugged target in TWS, or is it an STT only situation?

 

Also, is the above true for different modes in reverse? When a target is cold and approaching the limits of the current radar scale, will it increment?

 

Thanks!

That's where I saw it!

 

So, two questions around:

 

"The range scale will automatically decrement when the TOI is at a range less than 45% of the range scale, and when the ACQ cursor is less than 5% of the range scale."

 

1. The ACQ cursor is the slewable box when using the TDC?

2. TOI is defined as an STT only, or does it apply to STT, SAM and TWS bugged targets?

[Frederf]

1. Yes. Most accurately the control is called the cursor/enable switch (enable refers to the press in button aspect of the control.) The part of the display in CRM that you move around is called the acquisition cursor.

 

2. TOI is target of interest is defined in any mode that has a bug and applies in SAM, TTS, TWS, VSR, etc.

[antsh]

Just checked and this doesn’t happen in TWS mode. Bugged a target at 60nm with a scale of 80nm. Kept tracking until he was within 10nm, and the scale remained at 80nm.

 

Same experiment with an STT moves the scale down as he approaches as you’d expect.

 

I’m assuming this is a bug or WIP because I can’t imagine a pilot would need to take his hands off the controls just to hit the osb.

 

Note: this is different than bumping the scale which I know doesn’t work in TWS, but I assume scale changes as a toi approaches should still adjust?

 

@Bignewey?

Emphasis

[Frederf]

AFAIK TWS should range scale down just like RWS-SAM or STT based on bugged target position. It might not scale down if certain other interesting symbols might leave the display like AIM-120 guiding on farther tracks but otherwise yes.

[antsh]

Bignewy said he’ll take a look. Mods, can we moved this to bugs?

[antsh]

Can this be changed from correct as is since my other thread was merged into this? @Bignewy said he would investigate, please note my emphasis above, this is different than range bumping.

[Deano87]

Range bumping should work in the downward direction in TWS I believe. At least it did on the Danish AMs my brother flew.

[antsh]

@BIGNEWY can you take a look at this one as well? I can't believe that the FCR doesn't reduce scale automatically in TWS mode (or that you can't decrease range manually, actually). Otherwise the pilot would have to either exit TWS mode, or take hands off the controls. This also has a knock on effect of having the DLZ scale being really compressed if you start using TWS while a bandit is say in the 80nm scale.

[Deano87]

My bro who flew Danish F-16AMs for 4 years around 2012 told me that you can reduce range with the cursor while in TWS... In fact he was extremely confused while using my sim over Xmas why he couldn't. I don't see why the Block-50 would be different from that... but who knows.
