Master Caution, Cathay seem to have it right.
This shouldn't happen but it does. I'm not going to criticise anyone as I've had my fair share of f$&kups over the years. This is a real organisational failure however.
Having 3 possible flight libraries seems to be a recipe for disaster. This is not the first time this has happened in QF. I know of at least one, possibly two, other occurrence(s) in the last 10 years. Until such time as a decent efb is introduced with all charts why not put the Pacific and Euro charts on all 400s and also put the Americas books on the -ERs?
Cost analysis on the risk of a diversion anyone?
