In order to enter a phantom waypoint that is designated by a VOR/DME simple RNAV system, the VOR/DME?

For a phantom waypoint designated by a VOR/DME simple RNAV (Area Navigation) system, the key requirement is that the VOR/DME does not have to be in range when the waypoint is entered into the system. This allows pilots to plan their routes even if they are not currently in proximity to that particular VOR/DME reference point. However, once the waypoint is being utilized for navigation purposes during flight, the VOR/DME must be in range to ensure proper navigation and position accuracy.

This way, pilots can manage their flight paths more efficiently by programming the phantom waypoints ahead of time, while still relying on the VOR/DME for verification and guidance when they are within range, thus maintaining situational awareness and adherence to navigation procedures.
