                     Operational concept
• Airborne separation category according to PO-ASAS
  classification
   – Delegation of responsibility from the controller to the flight
      crew to execute a crossing manoeuvre with respect to one
      designated target aircraft.
   – The controller remains responsible for the separation with
      respect to the other aircraft in the sector.
• Conditions
   – This is post AS/GS package I and ADS-B IN (and data link)
      would be available.
   – Traffic conditions would be similar to current situation for
      Controller tools.
• Related Programmes
   – MA-AFAS, MFF, IAPA

           AIRBORNE SEPARATION

• Airborne separation will be based on airborne
  surveillance and airborne navigation.
• The typical values could be expressed in TIME rather
  than DISTANCE.
• Safety studies are required before promoting any
  reduction in the current ATC separation minima.
• ASSTAR assumed several typical values for the
  applications:
   – 5NM for ASEP-C&P in radar airspace
   – 10 or 15 NM for ASEP-ITP in oceanic airspace
   – 2 minutes or 5 NM for ASEP-ITF in oceanic airspace

           Objectives for this session

• One year ago in Rome, information on approach, methods and
  feedback from the audience, …including critiques….


• The session of this afternoon is dedicated to present
  ASSTAR findings on the various applications:
   – Definition of the procedures (Applicability conditions,
     phraseology)
   – Operational benefits (safety, capacity, workload and task
     sharing)
   – Airborne systems requirements (algorithms, architecture)




                                                            8/10
