Thank you Richard to that DIRECT LINK to the Night Flights section on the BAA? page.I've pasted some of it below.We are aware that the present agreement allows for 5800 flights EACH YEAR to arrive before 6am...but what is particularly revealing is the clause which allows extra flights to arrive if the noise levels fall into particular categories. Now, I haven't been aware of that loophole before.The (six year?) agreement between the Airlines(?) and the Government to allow that 5800 to land so early expire last October..and was extended for a further 12 months. Apparently the Government had dragged its feet in getting around to a new six year agreement ..so the old one was extended for 12 months...probably to await the arrival of quieter aircraft later this year.One again I believe we have here another subject clouded with INFORMATION FOG..and recent disclosures that the Kew Gardens Authorities are given financial sweeterers to stay quiet does nothing to make one think otherwise.FROM THAT HEATHROW WEBSITE..REGARDING NIGHT FLIGHTS."""The decision to allow night flights, therefore, is a policy matter for the Government.The most recent restrictions were introduced in October 1999 and consist of three main elements as follows: * A maximum number of flights during each season (3,250 in summer and 2,550 in winter) between 23:30 and 06:00 * A supplementary quota system to encourage the use of quieter aircraft. Aircraft types are given a Quota Count (QC) value, according to how much noise they make on landing and take-off, of QC 0.5, QC1, QC2, QC4, QC8 or QC16, the noisiest category being QC16. Aircraft movements score these QC values against a maximum allowable Quota for each season (5,610 for summer and 4,140 for winter) between 23:30pm and 06:00, 'the night quota period'. * Aircraft of QC16 and QC 8 cannot be scheduled to operate between 23:00 and 07:00.Normally there are no scheduled departures between 23:30 and 06:30. There is only one scheduled arrival after 23:30 which is a mail flight, until the early morning arrivals which make up most of the night flights. The first is scheduled at around 04:55 but they can arrive earlier. Occasionally, aircraft operate after 23:30 because they have been delayed, e.g. due to bad weather, or they are small, quieter aircraft which are therefore exempt from the restrictions e.g. medical flights.""" END.Its not even clear from the about paragraghs whether the 5800 is correct. As I say INFORMATION FOG.
