3. Flight Information Service becomes Basic Service
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. Flight Rules/Meteorological Conditions IFR or VFR, VMC or IMC
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. The pilot is wholly responsible for collision avoidance.
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. A controller shall provide deconfliction instructions by allocating
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. Terrain clearance would be achieved:
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. Lateral, Longitudinal and Time Restrictions
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. What will this mean at Carlisle Service principally aimed at :
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.
