2021-06-09 - LAC North Splitting Procedures


Harry Sugden

Recommended Posts

Valid 9 June 2021

For Manchester Midweek Madness, in order to manage the increased workload in the North sector group, a temporary arrangement is made to allow for the splitting of the London North sector.

 

AC North - LON_N_CTR (Relief: LON_N__CTR)

Frequency: 133.700 MHz
RTF callsign: London Control
Coordination callsign: AC North
Top-down responsibility for: AC Lakes & North Sea; PC West & East

AC North is the parent position of the AC North group, as published in the London FIR (EGTT) vMATS Part 2.

 

AC Lakes - LON_NW_CTR (Relief: LON_N1_CTR)

Frequency: 135.575 MHz
RTF callsign: London Control
Coordination callsign: Lakes
Top-down responsibility for: None

AC Lakes is responsible for airspace West of a line passing approximately GOLES-NAPEX as shown in Figure 1. Unlike the AC North (133.7) position above, this position does not take ownership of the PC sectors beneath when they are not online.

 

North Sea - LON_NE_CTR (Relief: LON_N2_CTR)

Frequency: 128.125 MHz
RTF callsign: London Control
Coordination callsign: North Sea
Top-down responsibility for: EGSH

AC North Sea is responsible for airspace East of a line passing approximately GOLES-NAPEX as shown in Figure 2. Their top-down responsibilities reflect their airspace (i.e. Norwich) in the absence of other controllers.

 

Agreed Levels

For AC North Sea controllers (LON_NE_CTR), an Agreed Levels Diagram is available:

There are no agreed levels between AC Lakes and AC North Sea.

      Effective 22 April 2021
      Alongside introducing the capability for more advanced splitting options in AC South, some associated changes are being made to the day-to-day sectorisation. This affects mainly airspace over central London in what’s known as ‘TC Capital’. There are also some minor changes to airspace elsewhere in the sector. A number of agreements are also affected.
      Note: This Procedure Change does not introduce any new positions. The airspace of some of our existing sectors is changing, along with some agreements.
       
      Sectors
      Summary of Main Changes
      The airspace up to FL215 over central London and to the east of the current high level Worthing-Dover boundary is being transferred from Worthing to Dover. Two portions of airspace on and around the MAY-VATON track are transferred from TC South East to AC Dover. A section of airspace southwest of GWC from FL125-FL175 is transferred from TC South West to AC Worthing. Slight changes have also been made to the AC West and AC Daventry sectors in areas to the north of KENET and KIDLI.
      Want to know why? This post talks about the TC Capital airspace and why we’ve decided to change the ownership here in a little more detail.
       
      Revised Diagrams
      These changes are represented on the updated Sector Diagrams available for review HERE.
      Additionally, the areas that have changed are shaded in red on the following figures:
      Figure 1 - New TC South East Sector

      Figure 2 - New TC South West Sector

      Figure 3 - New AC Dover Sector

      Figure 4 - New AC Worthing Sector

       
      Agreements
      A number of agreements are affected by the changes to sectorisation, and there have been two further changes to agreements for EGLF outbounds via OTSID-BIG and Essex/Thames outbounds via LYD.
      The draft Agreed Levels Diagrams for 2021/04 are available HERE. Please note that further changes will likely be made before the release date, so it is important to download the final published version.
      The changes are available in table format here:
      Changes to Agreements.pdf
      The most notable changes affect:
      EGKK LAM departures - which are now transferred from TC South East to AC Dover (previously Worthing); and  Essex inbounds via VATON - which are now transferred from AC Dover (previously Worthing) to TC North East. -----
      Tip! If you prefer to visualise things, I recommend opening an existing Agreed Levels Diagram and the new one (linked above) side by side and flicking between them to look at what has changed. For example:

      TC Capital Ownership Changes
      As part of a suite of changes to the South sectors related to preparations being made for new event splits in South, the ownership of what’s known in the real world as ‘TC Capital’ is changing.
      Previously, all of the TC Capital airspace (consisting of TC CPT and TC VATON) was part of our Worthing sector. This was the reason - to take a commonly used agreement - that Gatwick LAM departures were transferred from TC SE to Worthing, who controlled the airspace up to FL215 in this area.
      From 2021/04, the TC Capital airspace is being divided up - TC CPT will be owned by our Worthing sector, and TC VATON by our Dover sector, when split. This should make the coordination sequence more logical for a number of agreements.
      The Figure below shows the new TC CPT/VATON division of airspace, labelled with the real world sector names.

      The Figure below shows the same airspace, but now labelled with our Worthing and Dover sector names:

      The dark blue line indicates the new boundary between Worthing and Dover, up to FL215. This means that almost all of the border between Worthing and Dover is now coincident at all levels, with the exception of a small bit of airspace to the west of the BNN-LON track (see the Procedure Change Post for full diagrams).
      We have also taken this opportunity to refine the ownership of TC VATON (soon to be owned by Dover) where it sits on top of TC SE, to better reflect the real world sectors. Two new boxes of ownership are created:
      South of a line running OCK-BIG (FL165-FL215), an extra level will be given to Dover (TC VATON) from TC SE - this is primarily for EGLF outbounds from TC SW. In a box north of MAY (FL175-FL195) airspace will be given to Dover (TC VATON), again from TC SE - this is to allow for the earlier descent of Essex inbounds via MAY to FL180.  
      Why have we changed this?
      There are a number of reasons as to why we have changed the sectorisation:
      It means that the lateral boundary between Worthing and Dover is now much simpler, running almost along one line for the entire length of where they meet (with the exception of a small section west of BNN-LON). It should make it easier for Clacton and TC SE controllers (and others) to understand ownership in the LAM area, with only one controller covering from the top of the TC airspace upwards, rather than two. Dover now has control over all of the northbound flow into Daventry - so they will control both Midlands inbounds via HEMEL and EGKK LAM departures. This makes it easier for them to position them correctly relative to each other, and also gives Daventry RFC for EGKK LAMs, even when Worthing and Dover are split. For traffic via BPK with TC East/Clacton, only one release for climb is now required. Previously, when Worthing and Dover were split, the TC E/Clacton controller would need an RFC from Worthing up to FL215, then Dover was on top. Now, all of the airspace here will be owned by Dover. The new DB-125 area in TC SW to the southwest of GWC resolves the conundrum of AC Worthing still having control of planes descending 130 by GWC/TELTU/HAZEL, yet already being inside TC SW’s airspace. The two areas of TC SE given to AC Dover as part of the TC Capital change gives Dover greater flexibility for the descent of Essex inbounds.  
      Essex Inbounds via VATON
      It is worth highlighting the changes to traffic via VATON that this new sectorisation introduces.
      Dover (as TC VATON) has to merge 3 streams of Essex inbounds, all from different controllers. It is extremely important to pay close attention to the release conditions:
      BANVA 1L - FL200 level MAY. This is no longer an agreement, but pilots will be expecting this descent, as per the charts. BEDEK 1L - FL180 level BEDEK from AC West. This traffic is not released for descent until within Dover’s airspace (i.e. passed OCK). It is ‘skipped’ by AC Worthing, but must not be descended in their airspace. If the traffic is not on a radar heading, then it is released for right turns only. AVANT/TELTU 1L - FL190 level AVANT/TELTU from AC Worthing. This traffic is not released for descent until within Dover’s airspace (i.e. passed OCK), regardless of whether TC SW is online. If the traffic is not on a radar heading, then it is released for right turns only.  
      Changes to Agreements
      These agreement changes are already summarised in the main Procedure Change Post, and are all reflected on the revised Agreed Levels Diagrams. But here I have added a bit of an explanation before each table that explains how and why the agreements have changed.
      AC West
      Inbounds into TC Capital Airspace
      One agreement from AC West is amended - this traffic will ‘transit’ through Worthing at FL180, but will be handed directly to Dover.

        Internal Worthing & Dover Agreements
      Inbounds via MAY/BISRU no longer need to be transferred from Dover to Worthing because they won’t leave Dover’s airspace. However, a new agreement is created for Essex and Thames Group inbounds via AVANT/TELTU into TC VATON’s airspace. This traffic is not RFD until within Dover’s airspace, unless otherwise agreed.
      Two outbound agreements are also removed, since the traffic no longer needs to be transferred from Worthing to Dover.
