Each year the Helicopter Club of Great Britain sets aside a day to give Heathrow controllers a jolly down the helilanes, the purpose being to acquaint ATC more closely with the abilities and special problems of helicopters, and to show 'em a good time. This year I believe it was May 11th, and about 15 controllers were expected. I wasn't there so I don't know.
I suspect that few members of the Club ever land at Heathrow, and this aspect of operations may be neglected in discussions. Perhaps it could be factored in next time.
These flights are good for both parties, and give us an opportunity to show how much we appreciate the assistance of ATC in the London zone.
