Heading in information window vs. heading in radar plot

Split off from the topic EDDF-Triangle.


Hello,
Yesterday evening, during my session [ using ATC Pie Last version ], i encountered a strange trouble but was not able to understand from where it come :

ALRAL was flying Connie [ Lockhead 1049h ], spot on my radar was following the right heading, but the heading display in the Information window [ small square that you can see when you select a spot was wrong ] .... that the first time i see that "error".

Could some bring me some "lights" on this problem ?

Regards
Daweed

Hello,

Quick note for the future: No serious debugging can take place following an anecdote described from memory, so if you observe something that looks wrong to you, please take at least a screenshot and point out what you think the problem is. The best thing yet is always to look for a scenario reproducing the error. For example here: does the same model lead to the same result every time? Your message does not even tell if more than the one named model is incriminated.

Now regardless, several things do not add up in your message:
  • your title mentions two heading displays, but your message only refers to one of them: what is the discrepancy observed?
  • "heading in radar plot" (title) and in "small square that you can see when you select a spot" (msg body): what are you talking about? there is no heading in numbers on the scopes.
  • "spot on my radar was following the right heading": what is the "right heading"? the one assigned?

Hello Micky, Sorry, next time will take screenshot ...

When clicking on a spot in radar screen, a small square is display (link to the spot), that what i am calling Information window.
in the "information window", you can see the call sign, the aircraft ICAO ident, alt when mode S is activate , speed and heading.

Heading assign to ALRAL and follow by him 204 , information display in the information window 194
Looking with the mouse pointer, spot was following 204 heading, if the problem occure again, next time i will take screen shot.

Regards

"...and heading"? Nope, there is no heading indication there, or on any real radar I have seen as it would be useless clutter on the screen. The graphical position history tail and course/vector lines give a better (visual) idea of how aircraft are tracking.

Please go to the quick reference (F1) and read section "radar tags" of the "Display conventions" (first tab) to learn exactly what data is shown in the text boxes.
If needed, a number heading value can be found in the radar contact details dock (Shift+Alt+D) and in the smaller selected contact toolbar (first value) for the selected contact when available. It is not a mode S reading, but computed by the radar.

The title is on the moderator (in this case me). :oops: I changed it when I moved the post from the topic EDDF-Triangle.
