§ Mr. NorrisMore data on aircraft type, engine fit and maximum certificated landing and taking off weights are required to classify aircraft under the new night restrictions system than under the present regime. Not all this data is available for past movements, so only estimates can be given. These are(a) about 6,000 in winter 1992–93 (b) about 6,225 in summer 1992 and (c) about 6,400 in summer 1993.

- (a) 3,413:1992–93 winter
- (b) 3,409: 1992 summer
