Noob Questions about Radar (Rio Seat)

[Larkis]

Hi everyone,

 

 

i currently work into the RIO Seat and try to work with the Radar but run into some points i dont fully understand. Sadly i wasnt able to see the full 2.5h Rio School. If my questions are answered in the video just tell me. :)

 

 

1.

Situation: Im in TWS Auto and got a track of 4 Bears and could fire the phoenix. Is there a reason to change to TWS Man and reduce Scan-Width and Bars? I know i got a better Track cause i got more reflections in the same time. But is that something that improve Phoenix-Performance? Or is there an other reason i should prefer a bether tracking over situational awarness?

 

 

2.

Situation: I got 2 Contacts on the radar and want to check iff. I lock the first contact, press iff -> friendly. i set the Track on friendly. Now i lock the second one and do the same. But while i do this i loose the track from the first one and when the radar catch it again its labeld as unknown contact. How can i save the marked tracks while i lock the next one?

 

 

3. How should read the single pulse radar on the DDD? I know on double Pulse radar variant i see the conclusion rate on the DDD. But without the double pulse i dont get that information. How can i read the DDD with that radar variant?

 

 

4. Situation: Our Awacs was shot down by enemy forces. When my plane enter the combat area i know there are enemys, i know the direction cause of RWR feedback but i dont know height or range. What the best way (or radar mode) to find them? or other example, my F14 ist on 15000ft and i got a contact message on 6000ft. Is there a way to find that contact more easily then moving the plane to 6000ft too? I know i can change the vertical angle in TWS Man. But how can i determ the right vertical position to get the target?

 

 

5. Similar question. I have a contact lock and both plares are on 6000ft. Now the target start to climb or to fall. Is there some sort of indicator to see that and readjust the vertical angle of the radar?

1. TWS AUTO actually isn't implemented yet and does nothing (AFAIK it just resets theb radar to default settings currently). So yeah, currently you absolutly should use TWS MAN for all TWS operation. In the real Tomcat the radar mode switches to TWS AUTO upon launching a Phoenix in TWS MAN and it will behave like that ingame once TWS AUTO gets implemented, so you won't really have a choice then once you fired.

 

2. You can't save tracks. If you loose a track which is what happens when you leave TWS, which you do when you switch to STT to hardlock a contact, but you don't have to hardlock a contact to IFF him! You can IFF just fine in TWS (or all other radar modes).

 

3. It's not double Pule and single Pulse. It's Pulse Doppler and Pulse. Pulse Doppler makes use of a special characteristic of frequenzy waves, the so called Doppler Effect or Doppler Shift, which is named after the austrian physicist Christian Doppler.

Regarding the DDD, its vertical scale shows closure rate in all Puls Doppler modes and range in all Pulse modes (including IFF).

 

4. Put the bar scan to the limit. To do that you can not use TWS, because it supports 4 bars at most, so you should do that in rws to use the full 8 bar search. As you know the azimuth from the RWR, you can narrow the azimuth scan to enable a quicker search pattern.

 

5. If you have a TWS track you can hook it and the TID will show you it's altitude in the upper left corner (alternate with range). In both, RWS and TWS modes, the TID will also show you the altitude in 10,000ft steps as a single digit on the left side of the contact symbol.

 

 

And a general remark: You seem to rely on TWS quite a lot. In my experience RWS is a much more useful mode when searching for contacts as it allows much more scan patterns. For example, I use 8 bars and 20° azimuth settings most of the time, sometimes 8 bars and 40°, which is both not possible in TWS, as TWS is only supporting 4x20° or 40°x2 search patterns at max. I only switch to TWS if I already have the contacts on scope that I want to track or engage.

Thanks for the answer QuiGon!

 

 

So single Pulse Radar work only on the DDD and visual is more like the Radar for for example the F18. I see dots depending of direction and distance? Thats all very helpfull. Thank you very much!

It's not a single pulse radar mode as i explained above! Pulse search sends a lot of pulses, not just a single one, but yes, it only shows on the DDD.

What do you mean by "visual"? There is no "visual" mode.

 

Thanks for the answer QuiGon!

You're welcome :)

O sorry, talkin pullshit haha.

 

 

What i mean was that Pulse Search act more like the visual of the radar from the F18. In the F18 you see contact-positions relatet to your own position. So you cann see bearing and range to target on the screen. Pulse Search work the same Way on DDD, while Double Pulse Search show the conlusure range on the DD and range an bearing on the TID.

 

 

Maybeyou could help me with the IFF? I try the trainin mission but it dont seem to clarify this point. How can i IFF a contect without locking him?

I see what you mean now. That's basically correct, with one exceptions: The basic Pulse Doppler Serch mode does not show contacts on the TID, only RWS and TWS (which are special Pulse Doppler modes) show them on the TID.

It's rather simple although it can get tricky in situations where friendlies and enemies are merged all over the place. I'll give you two examples for how IFF works in the search modes (meaning non-STT modes).

 

Situation 1: You have two contacts ahead of you, one contact is hostile and is 20° to the left of your nose, while the other contact is friendly and 20° to the right of your nose. You see those contacts as blips on your DDD (in all search modes) and as symbols on your TID (in RWS and TWS modes). If you now press and hold the IFF button, you will see on the DDD, that the blip of the rightside contact will now get bracketed by two horizontal bars, indicating a positive IFF response, meaning he is a friendly, while the blip on the lefthand side remains unchanged.

 

Situation 2: You have two contacts ahead of you again, but this time they are both directly ahead of you at 0° of your nose. The friendly is 20nm ahead of you, while the enemy is 40nm ahead of you and both are comming towards you at the same speed. Let's assume you are in RWS or TWS mode. In this case the DDD will not show you the range of the contacts, but their closure rate instead, and as both contacts are comming towards you at the same speed, the DDD will show both blips at the same position. The TID on the other hand does give you range and will display the exact positions of both contacts and there you can see that one contact is at 20nm and the other is at 40nm, both closing in on you. If you now press and hold the IFF button, the DDD will change its display to pulse search style, meaning it will now show range instead of closure rate and now the blips will be seperated and shown at their respective range and the lower contact will be bracketed by two bars, as he is responding to your IFF interrogation, while the upper contact will remain unchanged as he is hostile. Now you know that the near contact is friendly and the other one is hostile, without having to lock them up.

Ha, never had the idea to hold the iff button.

 

Thanks! Will try that next time.

Holding the button is how it is supposed to be used. You can only do it for up to 30 seconds at once AFAIK.
