At present, the format in which Simbrief outputs VOR radial & distance waypoints does not work with the Collins FMS. To enter the waypoint manually in the correct format do (VOR IDENTIFIER)(RADIAL)(FORWARD SLASH)(DISTANCE).
Examples
Shannon Radial 237 @ 40 miles: SHA237/40
Cork Radial 049 @ 27 miles: CRK049/27
Dublin Radial 345 @ 17 miles: DUB345/17
The above can be entered into the scratchpad and subsequently the flight plan just like any other waypoint.
