Hi

Just been using the very latest iPad version today, v3.6.0 and noticed an airspace bug on the virtual radar

I had created a user waypoint just north of Liverpool's CTA just abeam Formby Point VRP

I noticed that when I change the track to use the user waypoint , the virtual radar shows my complete journey (I had planned due North up to Barrow) now in blue showing I am in Liverpool's CTA (from 1500' to 3500')

If I move off the user waypoint by the smallest margin, the virtual airspace radar is depicted correctly (ie. the CTA is not shown at this point as I am outside it)

Here are a couple more screenshots showing 2 more adhoc waypoints that do or don't show the bug

Thank you. This is almost certainly a regression introduced by our comprehensive handling of the issue dealt with earlier in this thread. While we (hopefully) solved the turningpoint-at-vertex issue we stopped detecting the turningpoint-on-edge case. This is quite rare - it will only happen when you've a turning point lying exactly on an airspace boundary - but as you can see, Liverpool is just one case. We have introduced a fix for the turningpoint-on-edge case, and this will be in the next version.
