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
