NOT FOR REAL WORLD USE
¶ General
¶ ATC Positions
| Position | IVAO Callsign | RTF Callsign | Frequency |
|---|---|---|---|
| London FIS | EGTT_FSS | London Information | 124.750 |
¶ Sector
¶ Area of Responsibility
London FIS is responsible for providing Flight Information Services within the lateral and vertical limits as shown in the diagram below except for:
1) Controlled airspace (Class A, C, D and E) below FL195.
2) Controlled airspace (Class C) above FL195.
3) Military Restricted airspace and Danger Area's.
¶ Responsibilities
1) Liaising with adjacent FIR’s if a flight crosses the FIR boundary.
2) Liaising with Adjacent Area/ Approach controllers when a flight is in the proximity of controlled airspace.
3) Providing Basic Services and information for the conduct of safe and efficient flights.
¶ Altimeter Setting
1) ATSUs are to have available the Regional Pressure Setting for the ASR in which they are situated and appropriate adjacent regions. These values are to be passed to pilots when requested or at the discretion of the controller.
2) Enroute aircraft are to be given the QNH At, or below, the transition altitude, i.e. in the vicinity of an aerodrome or beneath specified TMAs and CTA's.
¶ Transition Altitude
3000ft (Outside of controlled Airspace)

¶ UK FIS
London Information is not equipped with a Surveillance Radar and therefore can not provide Radar derived UK Flight information services such as a Traffic or Deconfilction service's. A Basic service is the only service London Information can provide.
¶ Co-ordination and Liaison
¶ Flights within the UK FIR
a) Aircraft who pass an estimate for the FIR boundary should have their details passed to the adjacent FIR if comtroller workload and communications permit.
b) If an aircraft reports at the boundary or has not passed an estimate they should be advised to contact the ATSU (Air Traffic Service Unit) in the adjacent FIR.
¶ Flights leaving the UK FIR
a) Details should be passed to the appropriate enroute ATSU (before reaching the FIR Boundary.
¶ Squawk Code Allocation
Aircraft under a basic service should be issued the London FIS Conspicuity code:
| Code | Function |
|---|---|
| 1177 | London AC (Swanwick) FIS |
Aircraft requesting a basic service should be instructed to squawk 1177 with mode C.
This SSR code is not used to identify aircraft, it is used to the benefit of other radar equipped comtrollers to show other that the aircraft is receiving a basic service with London Information.
¶ Phraseology
¶ Basic Service

¶ Flight Plan activation to Join controlled airspace
Part 1 - Basic Service and Flight plan activation
Pilot: “London Information, G-ABCD, Request Basic Service and Flight plan activation and controlled airspace join”
ATC: ”G-ABCD, London Information, Squawk 1177 with mode C, Pass your message”

ATC: “G-CD, Basic Service, Wessex 1001, Flight plan activated time 25, Squawk 0023, Remain outside of controlled airspace”
Pilot: “Basic Service, Wessex 1001, Squawk 0023, Remain outside of controlled airspace, G-CD”
Part 2 - Controlled airspace Joining clearance
ATC: G-CD, London Information.
Pilot: Pass your message, G-CD.
ATC: “London Control clears G-ABCD to join controlled airspace on track BCN, Climb FL250, Squawk 4323”
Pilot: London control clears G-ABCD to Join controlled airspace on track BCN, Climb FL250, Squawk 4323. G-ABCD”
ATC: “G-CD, correct, Contact London Control 126.075’”
