There's also a common feeling with many Crewing / Rosterers /
Manager type folk that if you got rid of CAP371 and started again
you could (with crew input) come up with a better scheme to suit
all parties. CAP371 is about 10 years out of date, its still got a rule in there that was used when 757's started going transatlantic and stoped in Bangor for fuel...
