HC Deb 07 March 1996 vol 273 cc308-9W
Mrs. Dunwoody

To ask the Secretary of State for Transport (1) if he will list for each major UK airport the number of aircraft taking off without take-off slots, together with the airline name and country of registration for each of the last five years; [19081]

(2) if he will list by each major airport the number of aircraft which arrived without landing slots together with the airline name and country of registration for each of the last five years. [19080]

Mr. Norris

No records are kept for UK airports of the extent of unscheduled take-offs or landings, that is, for which no slot has been obtained in advance. However, an assessment for Heathrow during June 1995 found an average of five unscheduled departures each weekday, in addition to opportunity slots obtained by business and general aviation. Most of the unscheduled movements operated by commercial airlines are maintenance, positioning or testing flights; only a minority, such as diversions from other airports, are passenger carrying.
