MBot Posted December 24, 2017 Share Posted December 24, 2017 The Terrain Avoidance radar mode is very unreliable. Sometimes it works, sometimes it doesn't display relevant terrain. Note that betwen the first and second screenshot, the terrain is displayed at almost the same range, while I closed a considerable distance to the mountains. I do not think that on screenshot 1 the terrain displayed are actually the mountains ahead but some ground closer (and lower). On screens 2, 3 and 4 the radar display does not match the terrain I see on the horizon line in the HUD. Link to comment Share on other sites More sharing options...
104th_Cobra Posted December 24, 2017 Share Posted December 24, 2017 On 1.5 Caucasus map, the information displayed on radar seems coeherent. Did you changed radar elevation? Changing radar elevation angle changes detection angle and information displayed... 104th Cobra [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
QuiGon Posted December 24, 2017 Share Posted December 24, 2017 I only fly on the caucasus map and there it worked just fine, so I guess this problem is map dependent.

TOViper Posted December 24, 2017 Share Posted December 24, 2017 Somewhere in the past I read about Tornado's problems with dunes (sand). The ground radar had obvious problems in receiving returns from dunes, thus the pilots had to watch out carefully. I cannot confirm the correctness of this story at this moment, I have to look to my older books. I hardly can imagine that this (if the above story was true) had been taken into consideration by HB. Furthermore you have hard terrain in front of you (stones, rocks). So it wouldn't make sense at all. Just wanted to point out that.

Holton181 Posted December 24, 2017 Share Posted December 24, 2017 If I'm not mistaken, you are supposed to "head for the black" to avoid terrain (contrary to other radars), and in the pictures it does seem to be black at the sides where you don't have any terrain while light to the front where you have the hill. Most obvious in the last picture. In the first you seem to be far enough from the hill to not be a threat, therefore a black arc over the entire lateral range. I haven't really put an effort to learn to use it efficiently myself, not in Caucasus nor Nevada, so a rather high possibility I'm wrong though. Merry Christmas!

While "black - no return" is the usual convention with radars, this is not actually the case with the Viggen. Here, black indicates a return.

River Posted January 11, 2020 Share Posted January 11, 2020 So what ? Black means mountains or white ? Thx Link to comment Share on other sites More sharing options...
MYSE1234 Posted January 11, 2020 Share Posted January 11, 2020 So what ? Black means mountains or white ? Thx Black is the returns, white is just nothingness as far as the radar knows.
