Where will the ATSOCAS rules apply? Classes F & G airspace, which is everywhere outside controlled airspace, and in active TRAs. …This is an… ‘unknown traffic environment’
4 levels of Service • Basic • Traffic • Deconfliction • Procedural
Basic Service Pilot: Maximum autonomy…. Without controller agreement – can alter heading, route or level at will. Controller/FISO: NO involvement in collision avoidance. Transponder code…can be allocated! IMC: NOT appropriate.
Traffic Service Pilot: Responsible for collision avoidance. Controller: Provide information about surveillance derived traffic that may conflict. NO avoidance advice. Aircraft has to be identified. IMC: NOT appropriate.
Deconfliction Service Pilot: Must be able to accept headings or levels that will take them into IMC. Controller: Provide information about surveillance derived traffic that may conflict. Avoidance advice given. Aircraft has to be identified. IMC: YES… not appropriate for VFR
Procedural Service Pilot: Responsible for collision avoidance. Must be able to accept routing or level instructions for flight in IMC. Controller: Non-surveillance service. Issues – headings, level and time instructions. IMC: YES…
Procedural Service • Provided at airfields without a surveillance system to aircraft on IFR approaches or departures. • Traffic information provided on known traffic. • Transponder code can be issued ..but..
