Mike I thought I had mentioned that above the Easterly SID graphic.
Oh - and on the Easterlies SID map:
The part of the Heliroute H3 between THORPE and TEDDINGTON is closed as it is not spearated from departure. Also, H9 needs a "southbound check" put on for southerly departures.
Ironically - Heathrow is the only CTR I have ever heard of that has a separate frequency and controller for the low level traffic. This is a huge drain on resources at TC - and at airports like Stansted you are just told to remain outside CAS if they are busy.
I think that each flight would need so much co-ordination it would be a drain on resources, and detract from the primary task of the ATCO. (shifting the IFR paying traffic).
As said above, I will agree to the controlversial statement that there are far too many people who fly and have difficulty flight planning and avoiding CTRs who couldn't be trusted to follow the rules and exact routeing.
There are enough helicopters that get it wrong just now - and questionable flying like the LCY diversion last week.
Sorry - back to the "far too difficult" tray me thinks - just to get people the opportunity to fly over heathrow.
