What is changing?What is changing?

Flight Information Service

becomes Basic Service

Radar Information Servicebecomes Traffic Service

Radar Advisory Service

becomes Deconfliction Service

Approach Control Service

becomes Procedural Service

What is not changing?What is not changing?

Alerting Service

Service within the ATZ

Friendly service from Carlisle Tower

Why change?Why change?

Prior to the ATSOCAS Review being initiated, AAIB andUKAB reports increasingly indicated either errors or alack of understanding by both pilots and controllers.

Feedback from CAA Safety Evenings highlightedfrequent variances in service standards and provisions.

There were differences between Military and Civil ATCprovision of Radar Information Service (RIS) and Radar

Advisory Service (RAS).

For the first time military controllers will be working froma Civil Aviation Publication.



66

Why change?Why change?

Some aspects of civil co-ordination phraseologyhas 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 bechanged,

You can not keep the same name if the ruleshave changed.

ICAO use the name FIS for the whole range of services, so the UK could not use it for only oneaspect!



77

Some of the key changesSome of the key changes

More tightly defined conditions for passing trafficinformation 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 aseparation';

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.

Basic ServiceBasic Service

Flight Rules and Meteorological

Conditions

IFR or VFR any meteorological conditions.

Identification Not required

Traffic Information None ± outside an Aerodrome Traffic Zone (ATZ),



99

Basic ServiceBasic Service

Deconfliction ± Pilots responsibility

Terrain - Pilots responsibility

Headings none, unless the pilothas entered into an

agreement

Levels none, unless the pilothas entered into an

agreement

How will this be done at CarlisleHow will this be done at Carlisle(1)(1)

After departure ATC will request your operation area andlevel.

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 closeproximity, information may be issued to the pilot. Theother 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 alocation to aid spatial awareness of other pilots.



1111

How will this be done at CarlisleHow will this be done at Carlisle(2)(2)

We will expect you to update ATC with your position andlevel 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 takeaction. We obviously respond to your Pan or Mayday.

With regard to flight within the ATZ, specific and, whereappropriate, 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 fromdeveloping a spatial awareness technique



1212

Procedural ServiceProcedural 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.



1313


Traffic Information

If it is considered that a confliction may

exist, on aircraft being provided with aBasic Service .

The pilot is wholly responsible for collision

avoidance.



1414


Deconfliction

A controller shall provide deconflictioninstructions by allocating

Levels, Radials,

Tracks,

Time restrictions,

Deconfliction from other Procedural aircraft Deconfliction advice cannot be provided against

unknown aircraft



1515


Terrain

Terrain clearance would be achieved:

when following notified instrument approachprocedures.

when climbing to the ATC unit¶s terrain safe level

However, if a pilot wishes to operate below ATC unitterrain safe levels, controllers shall advise the pilot of theterrain safe level and remind him of his terrain

responsibilities.

Pilot remains wholly responsible for terrain clearance atall times.



1616


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.



1717


What will this mean at Carlisle

Service principally aimed at :

IFR departures,

NDB approaches,

Flights in IMC

Remember ± NDB approach ± there may beunknown traffic

PhraseologyPhraseology

Generic Traffic Information

When providing a Basic Service, thecontroller may provide traffic information in

general terms to assist with the pilot¶s

situational awareness

Basic PhraseologyBasic 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 Carlisleand Wigtown below altitude 500 feet¶.

PhraseologyPhraseology -- Traffic ServiceTraffic Service ± ± DescentDescent

ATC: µ(Aircraft identity), taking your ownterrain clearance, descent approved¶.

Pilot: µMy own terrain clearance, descent

Traffic ServiceTraffic Service

A Traffic Service shall only be provided by

a controller with access to an

ATS surveillance system i.e. Radar



2323


Flight Rules and Meteorological Conditions

IFR or VFR and in VMC or IMC

P ilots 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, informthe pilot that he is identified, and maintain

identity.



2424


Traffic Information

The controller shall pass traffic informationon relevant traffic, and shall update the

traffic information if it continues toconstitute a definite hazard,

Deconfliction

Pilot is expected to discharge his collisionavoidance responsibility withoutassistance from the controller.

Terrain

Traffic Service may be provided below ATC unit

terrain safe levels; however, pilots remain

responsible for terrain clearance at all times.
