Hi. I'm wondering if there is an issue with the WCO NDB and Aylesbury gas venting danger area on Skydemon V2.2.1.21617 on my computer. (Not tried on the GPS yet).



If you zoom in to 1:55000 or better then the NDB appears to be in the correct location. However the danger area is not displayed.



If you zoom out to 1:65000 then the NDB jumps ~0.4nm north. There is a near invisible grey line from the centre of the NDB to the correct position. Still no danger area.



If you zoom out further then the danger area is displayed, however the NDB remains displaced to the north. The offset increases to over a mile in error.



I picked this up as I did some NB tracking work today. At the 1:160000 scale SkyDemon defaulted to it looked like I had missed the NDB by almost a mile which did not match what my instructor or the ADF was telling me. When I zoomed in close I found I had actually been quite close.



See images:

Displacing NDBs is normal behaviour. It's even done on the paper CAA charts.



Can't answer about the missing has venting site though.

OK, but if thats the case please could the thin, light grey line leading to the correct position be replaced with something a bit more obvious. Cheers

As Steve says, displacing of radio aid symbols always happens when they can't be shown at their actual location due to other overlapping objects. We have no immediate plans to change the way these are linked with their actual position (it's always worked that way) but that would change given a consensus of feedback.

Gas venting sites as with all airspace depiction will disappear when you are zoomed in to a very large scale (1:70000 approx). Such zoom scales are normally used around airfields when it's beneficial for the airspace to disappear in favour of greater ground-level detail.
