To be honest... I thought majority of places made the MATZ 'sterile' for +/-15 of the ETA/D? And then once the AC is airborne, its Ops Normal?Maybe im wrong.
I know in my time in the RAF they would stop movements for arrivals/departures, and restrict circuits due to purple airspace?
Im constantly seeing NOTAMs popping up due to VIP movemements that may cause disturbance to schedules.
