The CAA statistics only relate to Air Transport movements and I assume do not include the Biz Jet Factor.
Correct! Corporate activity at LTN represents around 20% to 25% of the annual total which is why despite LCY's air transport movements beginning to catch up on LTN's, the latter remains well ahead on total rolling annual/monthly movements. Some of LCY's 'busy hours' are achieving the same movement rates as LTN's (30+) which, given the lack of adequate infrastructure (airfield and airspace) at both, is a real credit to air traffic control at these two locales. And despite having 'cunning plans' in the pipeline, the planners are as is so often the case in this Country, way behind the doers...
