This paper led to Quiet Continuous Descent Approaches into London Heathrow in 1975 and transformed life in central London, it also led to related articles being published in Flight International, the Guardian and the Economist.
Abstract
FUEL conservation has always been a major factor in efficient airline operations but it is being
highlighted by the present crisis (1974). During climb and cruise it is relatively simple for a pilot to
extract the best performance from the aircraft, mainly by flying at the correct speeds and at the
optimum altitude for the aircraft weight. But during descent and approach practical information may
not be so readily available which can lead to a considerable drop away from optimum efficiency.
Poor descent and/or approach operation dramatically increases the amount of fuel burnt - at least 20
per cent on a short sector - besides making life under the approach path unnecessarily noisy.
