That's what I was thinking.Yes, and that was @DanMan32 's point. The Aircraft needs to broadcast the RC's location. However, the RC only knows its own location if a mobile device with a GPS is attached to it, so how would the Airfract get and broadcast the remote's location for non-GPS mobile devices?
I wonder if without that, it could be classified as a Remote "module" which only has to broadcast the takeoff point, but is limited to VLOS if, in the future, other RID implementations are not limited VLOS.
Of course taking off without a mobile device there's no RC location at all, but DJI already limits altitude/distance in that situation, which almost guarantees VLOS.
No technology can enforce VLOS, except maybe a brainwave monitor.
