I know pilot created waypoints are possible in the FMS but I don't know much more beyond that.
I hadn;t had a reason to figure them out until recently. I was flying online and received the instruction: "cross and maintain xx ft 50NM SW of the xx VOR"
I know there must be away to input a pilot waypoint that is a specific radial and distance from a VOR, right? My solution was to use the fix page and simply fly on V/S down to the SW 50NM point but I would much rather have used VNAV with an inputted restriction in the FMS.
