London Heathrow Airport. London’s Heathrow is one of the world’s busiest airports. It is used by over 90 airlines flying to 170 destinations worldwide. The airport has five passenger terminals and a cargo terminal. In the 1950s, Heathrow had six runways, now it has just two parallel runways running east-west. Heathrow has witnessed strong growth over recent decades, currently handling 68 million passengers and 477,000 flights a year compared to around 48 million passengers and 427,000 flights a year in 1996. In the absence of any increase in runway capacity, this growth has resulted in Heathrow’s runways operating at around 99% capacity compared to its main European competitors which operate at around 75% capacity, leading to increased…show more content…
The quieter the aircraft the smaller the QC value. Aircraft are classified separately for landing and take-off. Heathrow operating the system have a fixed quota for each of the summer and winter seasons. As each night-time aircraft movement takes place, an amount of this quota is used depending on the classification of the aircraft. For example, the Boeing 747-400 is classed as QC/2 on landing and QC/4 on takeoff, while the much larger Airbus 380 is rated QC/0.5 on landing and QC/2 on takeoff. The quieter A380 aircraft therefore use up an airport's noise quota between a quarter and half of the rate of the 747, thus providing airlines with an incentive to operate quieter types of aircraft. The ‘night period’ is 2300 – 0700 hours (local time) during which period the noisiest types of aircraft classified QC/8 and QC/16 may not be scheduled to land or take-off. From 2330 to 0600, the ‘night quota period’, aircraft movements are restricted by movements limits with noise quotas as a supplementary measure. In December 2006 the government published the Air Transport White Paper Progress Report 2006 to report on progress made in "… delivering a sustainable future for aviation”. The Air Transport White Paper stated that in addition to controlling and reducing aircraft noise impacts, a proportion of the large economic benefits provided by airport development should be used to mitigate their local impacts. The principal mitigation measure for aircraft noise
