Is the TIBA airspace semi permanent or is it just Notam'd day by day as needed? What airspace are they doing it in?
Notam'd when needed- result of staff shortages. I saw it happen just last Sunday afternoon going into Melbourne. Aircraft departing/arriving into Melbourne and even going Sydney Perth were
some of the routes affected.
Pretty 3rd world I think...
I wonder if the airlines get a discount on Nav charges for lack of service. Gotta love the management at AirServices.
