CJ: all due respect for the challenges your operation faces, but correct me if I'm wrong, is it not you that has the requirement for a change in the longstanding airspace/air traffic service requirements? And are you not a commercial outfit? Since you require something better than the existing arrangements, in our wonderful the-market-is-the-solution-to-everything world you ought to pay for it, and not fly in that airspace until it is provided if you consider it unsafe. In the UK the CAA to its credit has now imposed a "recommendation" that any UK operator proposing to start new public transport flights to/from an airport in uncontrolled airspace must prepare a safety case and have it approved by the CAA. No indications of what happens if the safety case concludes that there is an unacceptable risk which can't be mitigated though...
