Radar screen.

[Muppetlord]

So I've been looking around a bit for an answer to this but I have only found documents in french. Which might not even have been about the thing I'm looking for, I wouldn't know..since it's in french ya know...

 

Anyway, I just want to know what everything means on the radar screen. I've been trying to figure it out by watching the videos Razbam has put out but I am at a loss.

 

EDIT: Updated picture. With all we know so far :D

 

 

 

So, could someone fill me in on this? I really don't understand what I'm seeing on the screen right now. :helpsmilie: (Not relevant anymore...Just here for context)

The numbers on top. They only appear on a locked target.

They are from left to right:

 

Target heading

Target closing speed

Target altitude

 

On the H symbol: Heading + closing velocity in mach.

Thank you! Since this is a French aircraft I'm guessing this is in Km/h and meters correct?

Aren't all NATO planes in Feet for Altitude? I think that is a NATO standard but I might be wrong.

French aircrafts use Kt and Ft.

But Kg for weight and hPa for altimeter setting.

Ooh. Good to know. Thanks! :thumbup:

So according to this image the target's closing speed is 1253 knots, which would translate to about Mach 2,2. Which is different from the 1.9 enclosed in the red box....Im confused...

 

Nevermind I figured it out. The red box does not indicate mach number, but approximate altitude in km, the speed of 1253 knots is the combined relative speeds between the M2000C and the target, which makes sense as they are closing head-on, the M2000C is doing Mach 1,2 and the target Mach 1. Easy, peasy....;)

1253kt/ M1.9= 659kt which seems right for Mach speed in low altitude.

 

target is heading 089 at 1949ft.

Ah ok, my mistake. So the number 1.9 does indicate Mach speed? (And not 1900 ft?)

[jojo]

They are from left to right:

 

Target heading/ Target closing speed/ Target altitude

 

On the H symbol: Heading (089) + closing velocity in mach (M1.9)

So what does that 1.0 (or 10?) number below the H symbol indicate?

[jojo]

Radar range display setting : 10 Nm

[OnlyforDCS]

Thanks :thumbup:

That number indicates radar range and is static. It just happened that in this case, the symbol was just above it.

According to the French Mirage 2000C manual posted elsewhere, I believe the "718" over "1.23" would be IAS in knots (718 ) over Mach (1.23).

 

The 65 in the opposite side could be the barometric altitude.

 

The last numbers , "230" and "1 4 3" I couldn't figure out, because only navigational HUDs are shown in the manual.

Sounds very reasonable. Good find!

You can't find because the manual is RDM, and that last data is RDI feature. :smilewink:

 

WPT 1

230°/ 4.3Nm

Great! I'll update the picture in the morning...or when I give up on trying to sleep.

[Muppetlord]

Alright, picture updated. Still a few things left to figure out.

 

And I suspect at least one of these to be incorrect so feel free to correct me if you see anything that's wrong.

Is the tape on the left the Vertical Speed Indicator? :detective_2: Just a guess. I have no clue. :thumbup: MJ

[Cantiga]

PIC/PID stand for Poursuite sur Information Continue(STT)/Poursuite sur Information Discontinue(TWS), but I could be wrong.

[Zeus67]

That is correct:

PIC = STT

PID = TWS

That was my first thought too, but as you said i have no clue too. :D

[Muppetlord]

Great! I'll make another update later then. But...Is there no distance to target anywhere? Or is that usually a thing that radar doesn't calculate?

Oh and btw, what does STT and TWS stand for?

 

Edit:

Nevermind found it.

 

TWS = Track While Scanning

STT = Single Target Track

 

Man I've got a lot to learn when it comes to radar usage and general BVR combat...Can't wait! :pilotfly:

Radar antenna vertical deflection. INOP for beta.
