Hey, come august, HKIA might have to shutdown one of the runways to park all 'em "shiny 777s".
Cathay linecheck scenario:
Ok chap, RWY07R in Hong Kong is NOTAMed out of service to park our brand new 777s that are not flying because we failed everybody on their upgrades. So you're half way across the Pacific and you're low on gas..Can you continue to Hong Kong based on the "Inflight reduction of normal fuel required" according to current conditions?
