Says it all really...from the CAA in the above document...
The operators of these aircraft will need to book a slot to enter the wide area of restricted airspace that will apply from 14 July to 15 August, but the CAA says few have done so.
From Biggin Hill...
As an example of what London area business aircraft airports can expect, Biggin Hill airport business development manager Robert Walters said about 180 slots specific to Olympics attendance have been booked with Biggin as their destination, but he expects many more. This is over and above the normal 1,200-1,800 business movements that the airport gets anyway, with July always at the higher end of the range. Walters advised booking slots soon because "their numbers are finite".
So Biggin have approx 10% more than their usual movements. Or in other words, about 5.5 slots per day overall during the 33 days of the games..no wonder Walters is encouaging bookings!
At our Airfield ( 12 miles from the games) with a 6000 ft runway we have, wait for it, ZERO bookings!
