Explanatory Note

(This note is not part of the Regulations)

These Regulations amend the Civil Aviation (Route Charges for Navigation Services) Regulations 1989 as follows:

• The co-ordinates defining the area of the Northern North Sea in respect of which flights made by helicopters between any point in the United Kingdom and an offshore installation are exempt from the Regulations are revised (regulation 2(1)).

• For the purposes of the detention and sale of aircraft for unpaid charges provisions contained in regulations 11 to 14 of the principal Regulations the Eurocontrol Organisation may request and not require the CAA to act on its behalf (regulation 2(2) and (3)).

• New unit rates and transatlantic charges are introduced, reflecting forecasts of costs and traffic for 1993, and taking into account the balance of over and under recoveries of revenue as compared with costs experienced by the countries participating in the Eurocontrol charging system in 1991 (regulation 2(4)).

• The unit rates in ECUs set out in regulation 2(4) and the amount of the charges in ECUs set out in regulation 2(5) (for transatlantic flights) are calculated by reference to the costs of provision of en-route navigation services in the participating countries in the Eurocontrol charges system, the amount of traffic using each country's airspace and the relationship of each country's currency to the ECU over a period agreed by Ministers of the participating countries. The interaction of these elements varies in each country. In calculating the revised charges the average of the exchange rates between the ECU and the currencies of the participating countries obtaining in the month of July 1992 have been used.

• The unit rates for Austria, Cyprus, Germany, Ireland, Malta, Portugal, Switzerland and Turkey have decreased on average by 9% and for Portugal (Santa Maria) by 23.9%. The unit rates for Belgium, France, Greece, Netherlands and Spain have increased on average by 21.3% and for Spain (Canaries) by 3.4%. Hungary became a member state of Eurocontrol on 1 July 1992 and its unit rate is included for the first time. The unit rate for the United Kingdom has increased by 1.1%.

• Bristol, East Midlands, Gothenburg, Istanbul, Kiev, Lamezia Terme, Leeds Bradford, Marseilles, Sofia and Venice airports are added to certain zones for the purposes of regulation 7 of the principal Regulations (regulation 2(5)).
