Being able to set abeam points and/or setting user waypoint references to VOR radials (or in fact radials off ANY object in the database) in the log would certainly provide a higher level of granularity in flight planning. I find this feature particularly useful for say knowing that after radial xxx on vor yyy clear of controlled airspace, to indicate a climb or descent say. Or perhaps if I know I will need to report abeam a position en-route, having this in my flight log would be great
