That's nothing! Where I work (for 1 day only on 7th July this year) the flow rate is 60 per 15 minutes on my half of the airfield and 45 per 15 mins on the other side.
Okay, I own up, I'm talking about the Silverstone Helicopter Operation for the British Grand Prix, but it is ATC, with each helicopter given a take-off and landing clearance. Movements for the 1 day can top 3000.
Scott - I suppose you're going to mention Oshkosh now. I've heard the tape -"Orbit downwind and let's get the final into this state!" Impressive!
Btw, in my day job (EGLL) we did a record 1360 movements a few days ago - so much for the downturn! (And this morning we peaked at 48 landers in 1 hour).
"Busy-ness" is relative anyway - I had a tape made of me doing GMC at 'LL a few years ago cos I remembered it as an extremely busy session. When I listened to it there were numerous gaps in the R/T. Then I remembered who my assistant (lighting operator)was!
