There aint an easy answer to that Slippers. Come and visit and we will explain. If the CSC is npt available, on some sectors flow could be relatively high (eg Clacton, Dover, Seaford, Daventry. On the complicated ones like LUS, Berry Head and Lakes the CSC has a rather different task and if there isn't one available then the flow restrictions should be very fierce. There is always pressure to move more aeroplanes now and some of us believe that the safety margins are being eroded. That is one of the reasons we don't like the PPP. There will be a ton more commercial pressure and the safety will be regulated by SRG. These well meaning guys do not have the resource to police the system properly in a hands on way (ie in the ops room with the authority to overule a gung ho supervisor or flow manager) but we are sure that our ability to restrict traffic for professional reasons will be curtailed by over zealous managers. We are a safe operation who do not want to be changed without a convincing argument.
