Your wrong. Your opposites are Ryanair swear by the 5 early, 5 late rosters and they can do many more hours than you in the day and week.
A FTL variation is required to move away from the current 3 early rule and any change has to be supported by medical evidence.
You can only complete that by applying a variation and at the same time run a fatigue trial. If it comes out that Pilots working 5/2/5/4 are more tired than random 6/3 then the 6/3 will rule or EZY start again. I suspect this will not be the case.
The whole issue is being overtaken by Industrial issues rather than Flight Safety.
Flappyfeet sums it up very well in my view. EZY and Balpa should be congratulated on the effort they have made.The UK Airline Industry can only benefit from this study as it will hopefully open up the early/late discussion.
