SATCO Biggin.... That is the point mate. There is no time on the RT for most Approach Controllers to get the stuff through CAS, let alone the stuff planning on going around.
Just look at the year on year increases in traffic say the last 5 years. How many "New" approach sectors or seats are there for the LTMA airfields????
Bose - it is not me saying that you are not wanted because you are not loved (in a GA Sense!) but you are sadly not wanted because we are busy dealing with the IFRs and zone transits!! I have lost count of the number of times traffic going from Elstree to Southend calls Thames when in the Stapleford overhead! It happens daily. (or is routeing DET-BIG-OCK and they get upset when I tell them to call Biggin for ATZ transit)
Have a look at the coverage of Southend LARS..... doesn't it nearly meet with Farnborough's coverage???
Farnborough have a book listing all the aircraft that they either dig or prevent from entering the Zones of Gatwick, Heathrow and Solent, not to mention the LTMA.
So, to sum: WE DON'T HATE GA.... WE DON'T REFUSE GA WITHOUT GOOD CAUSE... We just don't have the TIME to deal with everyone outside CAS. DON'T BLAME US!
