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

Navigational Aids

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
