Stiffwing,
Oops yes I checked today. Our copy of your FP shows TAS, usually 430- 455.
Lots of useful things we used to get are no longer available eg clias, pob..
Yes we are privy to your schedules via the CTMS and ATFM systems.
We and the airlines have access to these sysems and use them to assess peak traffic periods.
Unfortunately they are an overview system and not available to the flow at his workstation so, no, we don't know if you are late/early/on time when we are organising a sequence.
That's the problem. we don't know what speeds you are going to fly.
I say again Q, V and J have advised use in writing that while there is a standard profile they will vary it at will depending on their requirements.
The flow controller at SY does not start work much before 6am so far as I am aware.
Yes, long range sequencing is in action throughout the night to try to maximise runway use from 2000 utc and to stop 8 aircraft arriving at the same time and holding at 40 miles.
I think [but have been wrong on a semi regular basis] the nighttime flow is now done from the noc shop in canberra.
Come in to a center anytime and see how we try to do things. You will always be welcome. After all we are actually working for you. The aviation industry pay the bills and therefore our wages.
