ATSOCAS

1. ATSOCAS AIR TRAFFIC SERVICES OUTSIDE CONTROLLED AIRSPACE Commences 12th March 2009 Presentation derived from CAP 774, delivered to Cumbria based pilots on 10th February 2009

2. PRESENTED BY • K PACKER, • MANAGER AIR TRAFFIC SERVICES • STOBART AIR • CARLISLE AIRPORT

3. What is changing? • Flight Information Service becomes Basic Service • Radar Information Service becomes Traffic Service • Radar Advisory Service becomes Deconfliction Service • Approach Control Service becomes Procedural Service

4. What is not changing? • Alerting Service • Service within the ATZ • Friendly service from Carlisle Tower

5. Why change? • Prior to the ATSOCAS Review being initiated, AAIB and UKAB reports increasingly indicated either errors or a lack of understanding by both pilots and controllers. • Feedback from CAA Safety Evenings highlighted frequent variances in service standards and provisions. • There were differences between Military and Civil ATC provision of Radar Information Service (RIS) and Radar Advisory Service (RAS). • For the first time military controllers will be working from a Civil Aviation Publication.

6. Why change? • Some aspects of civil co-ordination phraseology has been harmonised with military phrases. • Military controllers will soon be working from a joint civil /military phrase book. • The contents of the packages had to be changed, • You can not keep the same name if the rules have changed. • ICAO use the name FIS for the whole range of services, so the UK could not use it for only one aspect!

7. Some of the key changes • More tightly defined conditions for passing traffic information under Basic Service; • Change from 'separation' to 'deconfliction' - more than just a name change, a change in culture and attitude - 'best endeavours' rather than 'must always achieve a separation'; • Procedural Service brought into line with rest of ATSOCAS suite of services regarding deconfliction of aircraft, flight conditions, etc.; • - Detailed information and guidance on duty of care; • Defined RTF for provision of ATSOCAS.

8. Basic Service • Flight Rules and Meteorological Conditions • IFR or VFR • any meteorological conditions. • Identification Not required • Traffic Information None – outside an Aerodrome Traffic Zone (ATZ),

9. Basic Service • Deconfliction – Pilots responsibility • Terrain - Pilots responsibility • Headings none, unless the pilot has entered into an agreement • Levels none, unless the pilot has entered into an agreement

10. How will this be done at Carlisle (1) • After departure ATC will request your operation area and level. • After departure, if relevant general information will be given i.e. PA38 near Gt Orton, last reported at 1500 ft. • If a controller considers that aircraft will be in close proximity, information may be issued to the pilot. The other aircraft requested to update their level and position information. The pilots are wholly responsible for collision avoidance. • A request may still be made to report turning over a location to aid spatial awareness of other pilots.

11. How will this be done at Carlisle (2) • We will expect you to update ATC with your position and level if you hear someone is likely to get close to you. • We also provide an Alerting service, no change there. If we don’t get a report that we are expecting, we will take action. We obviously respond to your Pan or Mayday. • With regard to flight within the ATZ, specific and, where appropriate, updated traffic information will be provided to aircraft operating in an ATZ. • However students will not be spoon fed information on joining or leaving traffic as this will prevent them from developing a spatial awareness technique

12. Procedural Service • Flight Rules/Meteorological Conditions IFR or VFR, VMC or IMC • Identification - No • Aircraft do not need to be identified in order for a Procedural Service to be provided.

13. Procedural Service • Traffic Information • If it is considered that a confliction may exist, on aircraft being provided with a Basic Service . • The pilot is wholly responsible for collision avoidance.

14. Procedural Service • Deconfliction • A controller shall provide deconfliction instructions by allocating • Levels, • Radials, • Tracks, • Time restrictions, • Deconfliction from other Procedural aircraft • Deconfliction advice cannot be provided against unknown aircraft

15. Procedural Service • Terrain • Terrain clearance would be achieved: • when following notified instrument approach procedures. • when climbing to the ATC unit’s terrain safe level • However, if a pilot wishes to operate below ATC unit terrain safe levels, controllers shall advise the pilot of the terrain safe level and remind him of his terrain responsibilities. • Pilot remains wholly responsible for terrain clearance at all times.

16. Procedural Service • Lateral, Longitudinal and Time Restrictions • Unless safety is likely to be compromised, a pilot shall not change radial, track, or time • Levels • Controllers will normally provide level allocations for positioning, sequencing, navigational assistance, or to achieve deconfliction minima.

17. Procedural Service • What will this mean at Carlisle • Service principally aimed at : • IFR departures, • NDB approaches, • Flights in IMC • Remember – NDB approach – there may be unknown traffic

18. Phraseology • If a pilot fails to request a service, the controller should normally ask the pilot to specify the service they require, apart from • As we do not have radar we will routinely apply a Procedural Service to aircraft carrying out • IFR holding, approach and/or departure procedures;

19. Phraseology • Generic Traffic Information • When providing a Basic Service, the controller may provide traffic information in general terms to assist with the pilot’s situational awareness

20. Basic Phraseology • GRNCH, gliding activity over Skelling Farm’. • GBJNN, multiple aircraft known to be operating 2 miles North of Anthorn’. • GOECM, PA28 estimating DCS at time 25, altitude 2000 feet’. • GCDRP, Hawk reported routing from Longtown to the south below altitude 500 feet’. • GJLIN, helicopter conducting power line inspection between Carlisle and Wigtown below altitude 500 feet’.

21. Phraseology - Traffic Service – Descent Below ATC Unit Terrain Safe Levels Pilot: ‘(Aircraft identity), request descent to altitude 1000 feet’. • ATC: ‘(Aircraft identity), taking your own terrain clearance, descent approved’. • Pilot: ‘My own terrain clearance, descent approved, (aircraft identity)’.

22. Traffic Service • A Traffic Service shall only be provided by a controller with access to an • ATS surveillance system i.e. Radar

23. Traffic Service • Flight Rules and Meteorological Conditions • IFR or VFR and in VMC or IMC • Pilots should be aware that a Traffic Service might not be appropriate for flight in IMC when other services are available. • Identification • The controller shall identify the aircraft, inform the pilot that he is identified, and maintain identity.

24. Traffic Service • Traffic Information • The controller shall pass traffic information on relevant traffic, and shall update the • traffic information if it continues to constitute a definite hazard, • Deconfliction • Pilot is expected to discharge his collision avoidance responsibility without assistance from the controller.

25. Traffic Service • Terrain • Traffic Service may be provided below ATC unit terrain safe levels; however, pilots remain responsible for terrain clearance at all times. • Headings • A pilot may operate under his own navigation or a controller may provide headings for • the purpose of positioning, sequencing or as navigational assistance.

26. Traffic Service • Levels • Pilots may select their own operating levels or • may be provided with level allocations by the controller for the positioning and/or sequencing of traffic or for navigational assistance.

27. DECONFLICTION • Only be provided by a controller with access to an ATS surveillance system. • IFR or VFR and in VMC or IMC • A pilot who is not suitably qualified to fly in IMC shall not request a Deconfliction Service unless compliance permits the flight to be continued in VMC. • Identification • The controller shall identify the aircraft, inform the pilot that he is identified

28. DECONFLICTION • Traffic Information • The controller may, subject to workload, pass traffic information on deconflicted traffic in order to improve the pilot’s situational awareness. • Deconfliction • A controller shall provide traffic information, accompanied with a heading and/or level • aimed at achieving a planned deconfliction minima.

29. DECONFLICTION • Terrain • A Deconfliction Service shall only be provided to aircraft operating at or above the ATC unit’s terrain safe level, • Unless when climbing to the ATC unit’s terrain safe level, or when following notified instrument approach procedures.

30. DECONFLICTION • Headings • A pilot may operate under his own navigation or a controller may provide headings for • the purpose of positioning, sequencing, navigational assistance, or to achieve deconfliction minima. • Levels • Controllers will normally provide level allocations for positioning, sequencing,navigational assistance, or to achieve deconfliction minima.
