Lateral flexibility around CLN
10 days ago I was departing Cambridge via CLN and SASKI towards Brussels in a light twin at FL70. (Frequencies after Stansted Director were 121.22 and 135.42) It was quite convective, and with hindsight I could have been rather more circumspect in my weather avoidance.
It would be useful to know how much flexibility there is to approve significant deviations north and south on that routing within the LTMA at that low level. Am I hemmed in by a constant stream of arrivals and departures passing me, or am I the only aircraft around at that level with a reasonable expectation of being able to ask for substantial (say 15 mile) deviations around weather? I'm aware that I run out of controlled airspace to the north and the Shoeburyness ranges are to the south, but is there likely to be significant conflicting traffic?
Thanks
