Two fifty
Thanks. That's what I would have thought. By the way It was not an ATC who did the bragging It was a person from middle management at AsA who was trying to show that it wasn't just business aircraft that were being refused entry into the airspace. ie - AsA were being consistent in applying the ban.
However there is one mystery. The ADSB regulation clearly allows for up to three days of operation in the airspace if the equipment is faulty. Why wasn't China Southern allowed this dispensation? Surely your ATCs know this dispensation is approved by CASA - or am I mistaken!
