"Qantas Chief Pilot, Captain Chris Manning, in a conversion with John Laws, has stated that the NAS is safe and added that if it were not, he would not allow Qantas to fly in unsafe airspace. Virgin Blue’s Chief Pilot has also supported the NAS."
If these two chief pilots are so enamoured by NAS, why is it that their crews amend their climb / descent profiles to remain clear of class E when their TCAS is US????
