LUS is an upper airspace split of the London South LAG, with airspace taken from both the Worthing and Dover sectors. Its area of responsibility is as shown in Figure 1. If LUS logs on, then AC South's area of responsibility is the normal AC Worthing and Dover combined AoR, minus that which is shown in Figure 1.

Coordination with Adjacent Sectors & Units

Maastricht UAC - KOKSY (Belux vACC)

The LUS controller must ensure that traffic cruising in their airspace via KONAN is level at its RFL by the western edge of the DVR RFC Area (EGTT vMATS LAC 3.4.3.9), else the traffic must be coordinated with MUAC. This traffic is considered 'known' to MUAC if it's at its RFL, thus enabling the RFC of LTMA departures via KONAN from Dover into LUS's airspace prior to the FIR boundary.

Brest ACC

The LUS controller must ensure that traffic cruising in their airspace via SITET/XAMAB is level at its RFL by the northern edge of the La Manche Release Area (EGTT vMATS LAC 2.4.1.8), else the traffic must be coordinated with the relevant Brest sector. This traffic is considered 'known' to Brest if it's at its RFL, thus enabling the RFC of LTMA departures via SITET/XAMAB from Worthing into LUS's airspace prior to the FIR boundary.

Daventry

Daventry must be informed when LUS is opened.

• EGCC/GP departures climbing FL310 will be transferred to LUS - Daventry must ensure they reach FL310 by the LUS boundary.
• MTMA inbounds that are transferred from LUS to Daventry are only RFD to FL310 (i.e. remaining inside LUS's airspace).

Clacton and AC West Sectors

There are no agreements with sectors within Clacton or AC West airspace. However, these controllers should be informed when LUS is opened.
