    Study Notes

    London FIR

    • Covers majority of England and Wales, controlled by London Area Control Centre (LACC) at Swanwick in Hampshire
    • London FIR includes en route airspace over England and Wales up to the Scottish border
    • LACC manages en route traffic in the London Flight Information Region

    London Area Control Centre (LACC)

    • Started operating in January 2002
    • Located at Swanwick in Hampshire
    • Manages en route traffic in the London FIR
    • Includes London Terminal Control Centre (LTCC), which handles traffic below 24,500 feet flying to or from London's airports

    London Terminal Control Centre (LTCC)

    • Handles traffic below 24,500 feet flying to or from London's airports
    • Issues routings and clearances prior to departure
    • Manages movement of vehicles around the airfield

    Aerodrome Controller

    • Divided between runway tasks ('AIR') and ground movement ('GROUND')
    • AIR: runway-specific tasks
    • GROUND: movement between stands and the runway vicinity

    Approach Controller

    • Takes over from area controllers as the aircraft approaches the airport
    • Gives initial clearance for the aircraft to approach the airport and sequences them for landing
    • May also handle the initial phase of flight after departure and any transiting flights in the immediate airspace

    Air Traffic Control over the Atlantic

    • Shanwick OCA (Oceanic Control Area) and Prestwick OACC (Oceanic Area Control Centre) responsible for air traffic control over the Atlantic
    • Clearances to cross the ocean include track, flight level, speed, and any time restrictions for entry on to the track structure
    • Planners on either side of the ocean consult with each other and coordinate with adjacent OACCs and domestic ATC agencies to ensure sufficient capacity for anticipated demands

    Radar

    • Primary radar provides basic information about an aircraft's position in relation to the radar
    • Secondary radar is selective and displays information from aircraft equipped with a transponder
    • Radar sites located at many airports and strategic sites around the country
    • VOR (VHF Omnidirectional Range) emits 360 radial signals for navigation, with a range of approximately 125 nautical miles
    • NDB (Non-Directional Beacon) emits a signal for navigation, with a range of approximately 25 nautical miles
    • DME (Distance Measuring Equipment) measures distance from the VOR
    • ILS (Instrument Landing System) provides guidance during landing, with directional cues
