Yep, unfortunately this got pushed out of our last few releases. We did recently discuss it again at our last development meeting and are looking to add it in soon. I'll revisit it again with Walter and Brian. Sorry for the delay in getting this added, I know it's been discussed, planned, then dropped a few times.
Question? to keep it simple and more likely to be added sooner. Would a simple "Touch a point on chart, or waypoint and then Activate a radial marker", then enter in the Radial degree and possibly To / From?
This would be a fairly simple approach and allow for a radial to/from to be set from virtually any point. For VORs, etc, we would need to use the databased magnetic degrees for the VOR as many have not been corrected since initial installation.
