CLN - Co-ordination with Brussels, Amsterdam and Maastricht

Question 1

Describe Brussels ACC AOR in relation to CLN.

Answer 1

Brussels ACC is responsible for L179 and L608 between FL55-FL245 east of the FIR boundary (east of RAPIX and SASKI) but not within the delegated airspace to the north.

Question 2

In the BULAM area, the use of which FL is permanently delegated to Brussels ACC from Maastricht Koksy?

Answer 2

FL250. Maastricht Koksy shall not assign this level in the BULAM area without co-ordination with Brussels.

Question 3

Transfer of radar control from Brussels to S14 is subject to what three conditions?

Answer 3

• Serviceability of the respective radars
• Serviceability of the direct telephone lines between the radar controllers concerned
• The transferring controller is to ensure a minimum radar separation of 8nm, constant or increasing, unless vertical separation is established

Question 4

How long before suspension of transfer of radar control or reduced longitudinal separation procedures must Brussels pre-warn CLN (via the Ops Supervisor and GS)?

Answer 4

At least 5 minutes, except in unexpected circumstances such as loss of radar/telephone service.

Question 5

What level are Brussels TMA departures (overflying LTMA) with RFL250+ transferred in the climb to, and where are they released for further climb?

Answer 5

FL250 and RFC at the KEGIT line.

Question 6

If L610 is not available east of RAPIX, due to EBR17/TRA14 activity, where will Brussels TMA departures with RFL250+ be routed?

Answer 6

Traffic will be tactically routed by Brussels towards L179 until clear of the danger area or at FL250.

Question 7

Who must Brussels ACC co-ordinate aircraft that are unable to make FL220 by SASKI with?

Answer 7

TC JACKO

Question 8

Outbounds from the Brussels TMA to which airfields/groups will be capped at FL210- to remain in TC airspace?

Answer 8

LC, KB, MC, ABBOT group, TC

Question 9

What is the S14P procedure for handling traffic originally planned at FL210- that subsequently requests FL220+?

Answer 9

• Brussels/Ams contacts S14P to make an approval request and S14P decides whether to accept or reject
• If accepted, Brussels/Ams are to advise S14P if the ACT as already been sent to TC JACKO
• If ACT has already been sent, S14P will complete a Field 8 amendment and force offer flight to themselves
• S14P shall then verbally cancel the flight with TC JACKO

Question 10

What is the S14P procedure for handling traffic originally planned at FL220+ that subsequently requests FL210-?

Answer 10

• Brussels/Ams are to co-ordinate the traffic with TC JACKO
• TC JACKO input a Field 8 amendment to ensure that the flight is correctly processed within NAS
• TC JACKO verbally cancel the flight with S14 who shall reject the TDL

Question 11

What are the conditions for transfer of radar control without verbal exchange of radar identity with Maastricht/Ams?

Answer 11

• Provided a minimum of 10nm longitudinal separation, constant or increasing, exists between aircraft
• Aircraft must be equipped with functioning Mode C SSR transponders displaying discrete codes
• Both PSR/SSR and direct radar-radar telephone lines must be serviceable

Question 12

Where can Maastricht Delta position an aircraft routeing M40 without co-ordination with CLN?

Answer 12

Direct LUSOR or on a heading towards LUSOR

Question 13

Traffic routeing Q63 (GALSO-ERING-KOPUL) must not be vectored south of which point without co-ordination with CLN westbound?

Answer 13

GALSO

Question 14

S13/14 shall not vector traffic known to Maastricht Delta further north than which point/area without co-ordination?

Answer 14

NOGRO; IBNOS Area A

Question 15

Where must traffic UNKNOWN to Maastricht Delta not be vectored/routed north of without co-ordination?

Answer 15

2.5nm from the northern edge of IBNOS Area A

Question 16

What are the conditions for transferring traffic from S12 to Maastricht Delta on parallel headings at/cleared to the same level?

Answer 16

• Both a/c are exiting UK airspace via SOMVA (C1)
• One a/c is exiting via C1 and the other REDFA (C2)
• Both a/c are exiting via C2 but neither is inbound to a German Group airfield

Question 17

If one aircraft on a parallel heading is cleared to a level within the Delta High/Middle sector and vertical separation will not be established prior to the FIR boundary, what are the actions of the S12P?

Answer 17

Co-ordinate the aircraft with the Delta Middle/Low sector (against another aircraft cleared into the High sector) or the Delta Low sector (against aircraft cleared into the Delta Middle sector). Unless advised otherwise, the aircraft should still be transferred to the frequency appropriate to the sector into which it is co-ordinated.

Question 18

When might LAC and Maastricht agree on the use of direct routeings and what conditions are associated with these?

Answer 18

During hours of low military activity. This agreement can be withdrawn at any time.

S12 should be aware that if the direct routeing results in aircraft passing within 10nm of the IBNOS A Area, then co-ordination with S13/14 is required.

Question 19

What are the conditions for Maastricht Delta transferring westbound traffic on parallel headings to S13/14 without telephone co-ordination?

Answer 19

• Minimum lateral separation not less than 5nm
• Aircraft not subject to FLAS are not at/cleared to same FL at the exit point
• Aircraft subject to FLAS at/cleared to same FL on parallel headings are acceptable, with KK inbounds always positioned furthest south

Question 20

What are the procedures associated with failure of OLDI link and telephone communications between Maastricht/Amsterdam/Brussels and CLN?

Answer 20

Pilots are to be instructed at least 5 mins prior to transfer of control point, to pass data on the appropriate frequency of the accepting centre for the purpose of obtaining an ATC entry clearance.

If this is not possible, the pilot shall be instructed to inform Maastricht accordingly, who shall then hold the aircraft within its AOR. After a minimum of 10 mins, instruct the pilot to re-establish contact with the accepting centre. This procedure is to be repeated until an onward clearance has been obtained.

Question 21

What is the procedure for passing details of formation flights to/from Maastricht?

Answer 21

Maastricht handle formation flights with radar separation increased by 1nm, and so require a 10 minute pre-notification from LAC.

Formation flights coming from Maastricht - LAC are to be given 10 minutes notice so that the aircraft can be notified to Swanwick (Mil).

Question 22

What circumstances may result in the suspension of RVSM operations and what FLs will be used by Maastricht/LAC?

Answer 22

If individual FLs are withdrawn, for example due to severe turbulence, and subsequently RVSM operations are suspended, co-ordination is to take place between Maastricht and CLN. The following FLs will be used:
Even (westbound): FL320 + FL380
Odd (eastbound): FL290, FL350, FL410

Question 23

How far can an Amsterdam outbound be turned on contact by S14 without co-ordination?

Answer 23

To the right - no further north of M40 centreline.

To the left - no further south than 2.5nm north of the Amsterdam S3 boundary.

Question 24

What are the conditions for transferring/accepting aircraft to/from Amsterdam on parallel radar headings without co-ordination?

Answer 24

To Amsterdam from S12:
- Traffic must not be vectored more than 5nm either south/north of REDFA

From Amsterdam to S14:
- Traffic via NOGRO/ABNED shall be vectored so that the aircraft enters the lateral boundary of the IBNOS B area prior to LUSOR. Headings must be chosen so that the tracks are in the general direction of LUSOR/IBNOS
