Thanks - silly questions arise because I have not flown into an event with slot times before. Should not be a problem - I am intending routing from Redhill to Tatenhill (likely overhead City airport as Farnborough NOTAMs suggest that West of Heathrow option is out). Refuel at Tatenhill and then I have only 50 miles to run-in to coordinate times - and plenty of fuel if I need to fly at max cruise.
See you Saturday
John
