The London (EGTT) and Scottish (EGPX) Flight Information Regions (FIRs) cover the enroute airspace of the United Kingdom and coverage for underlying approach or aerodrome positions that are not online ("top-down"). The London airspace is split into sectors that may seem daunting at first, but are easy to understand if you take a few minutes to digest the information below. The main London sectors (North, South, Central & West) are shown in the diagram below. These sectors are able to be split further during high traffic situations.

The diagram below illustrates the most basic of splits for Scottish (SCO_CTR) airspace. SCO_CTR covers both areas in the absence of a split controller.

If there are no aerodrome or approach services at your departure aerodrome, use this list to determine which area sector to call. Contact the first controller listed that is online. If in doubt, don't be afraid to ask. Another good place to check is the controller information, where information is usually displayed as to which areas the controller is covering.

Radio Callsigns

All area control sectors within the UK (listed above) are called either "London Control" or "Scottish Control" over RT. London Area (LON) and London Terminal (LTC) Control are referred to as "London Control", regardless of which sector you are speaking to. Equally Scottish Area (SCO) and Scottish Terminal (STC) Control are referred to as "Scottish Control" regardless of sector.

The Manchester TMA sectors (MAN) are splits of the London North sector, however are referred to as "Scottish Control" when open. When only the parent sector, London North (LON_N), is online they are still referred to as "London Control" regardless of which part of the sector you are in.

Information for Controllers

For the purpose of controller bookings, the 'Primary Sectors' are defined as:

• LON_S_CTR
• LON_C_CTR
• LON_W_CTR
• LON_N_CTR
• SCO_CTR

The 'Secondary Sectors' are defined as:

• LON_D_CTR
• LON_E_CTR
• LTC_S_CTR
• LTC_N_CTR
• MAN_CTR
• SCO_CTR

Members may open either a single Primary or Secondary sector, or a valid combination of Primary (e.g. LON_SC_CTR) or Secondary (e.g. LTC_CTR) sectors.

Further splits require the remaining portion of the Primary or Secondary sector to be staffed too - e.g. opening LTC_NE_CTR requires LTC_NW_CTR (as the remaining portion of LTC_N_CTR) to be online.
