Select Committee on Transport, Local Government and the Regions Appendices to the Minutes of Evidence

Supplementary memorandum by the Department of Transport (NAT 2B)


  On 20 May David Jamieson wrote to the Committee Chairman providing additional information requested by the Committee at its hearing on 1 May. You subsequently telephoned me, and asked if I could provide tables of figures for the graph that was mentioned in paragraph two of Mr Jamieson's letter, together with figures for other major incidents that had an impact on transatlantic flights.

  I enclose tables of figures for Lockerbie, the Gulf War and 11 September. It is the figures in the "Transatlantic Flights % growth" column which have been transferred to the graph that was previously forwarded.

  In our conversation we also considered other events for which figures could be provided. We mentioned the Falklands War in 1982, but that had no impact on civil flights across the Atlantic. The two events prior to Lockerbie which did have an effect were the oil crisis in the mid-seventies, which we discussed, and also the oil crisis at the beginning of the eighties. I accordingly enclose tables of figures relating to them.

  In the tables, the percentage growth figures represent growth by comparison with the corresponding month in the previous year. A "CSU" is a chargeable service unit, which is the basic unit of charging for en route air traffic services agreed within Eurocontrol. It takes account of both aircraft weight and distance flown. A flight of 100km by a Boeing 737 aircraft approximates to one CSU.

  I hope this information is useful.
