Ominously, it is now being postulated that LARS/ATSOCAS is not there for the benefit of GA but for the benefit of commercial aviation, as it becomes a CAS protection service, thus making CAS safer, or outside CAS, for protecting commercial operations.
All it needs is the CAA to decide that CAS isn't quite safe enough and lo, you will provide LARS/ATSOCAS at your cost, otherwise you will not be safe! Job done, everyone suitably stitched up!
