Today there is flow into YYC. Sky is clear wind 160/6, vis 40sm. I do not understand..........., please tell me it isnt because NavCanada is too cheap to staff the Tower/terminal properly. There must be a good solid reason. Must there not? Anyone? CYEG66? Burly?
<sigh>.............
Blue sky isn't magic. It doesn't allow for disregarding separation. Flow into Calgary will be omnipresent every Tue, Wed, Thurs, for the next 4+ years. It will still be required many Mon and Fri nights. It ain't going anywhere. No, staffing not an issue. It is because of the following slightly unscientific example.
Familiar with flightaware? It doesn't account for 100% of air movements, but it can still give you an idea. Let's assume it misses the odd one from each of the following aerodromes:
Montreal 5:00 to 7:45 pm = 53 arrivals.
Vancouver 4:00 to 6:45 pm (most recent available time) = 67 arrivals
Calgary 5:00 to 7:45 pm = 78 arrivals
I'm no genius (very far from it,
) but it looks to me that
even with flow control in effect, Calgary was the busier over those parallel equipped airports. I can only speculate as to why.... Without the flow, the demand may have been well over 100 planes for that same period. The others don't even require flow. That number of arrivals
was the demand. It may differ throughout the day (YVR busier in the morning, for instance) but mid-afternoon to 9 pm will almost always be flowed mid week, regardless of weather, staff, Canadian controllers suck compared to American controller arguments, etc.
Turn right/left heading XXX, vectors for the hell of it.
