How precisely do you see current UK ATSOCAS as inconsistent with SERA?
Thank you for using the word 'inconsistent' rather than 'non-compliant' because it prompted me to review my previous post and I realised I had made a couple of errors - to be corrected shortly.
I know the CAA defines ATSOCAS as FISs and considers them compliant with SERA for use in Class G. However the services offered under the ATSOCAS banner are inconsistent (to a significant degree) with provision of FIS elsewhere in the EU, not to mention the rest of the world. So how do UK ATSOCAS fit into SERA? If you view SERA as an exercise in compliance, they fit. If you view SERA as an exercise in consistency and removal of national differences, they don't.
