The UK Airlines had just come out of months of negotiating with Jar Operators over an EU FTL.. .When they raised CAA related issues such as reduced FDP given the amount of sectors flown. .(medical evidence available to show awareness reduced the more sectors operated) and minor . .things like early / late rules, the EU Airlines just laughed and said "we've been doing it for XX years so it can't be dangerous". You can perhaps understand their frustration that the CAA are attempting to use selective medical advice to adapt CAP371.
