Would you please explain a bit further MrAP? I think that the description explains everything, it is just for recovery not to actually lead a social life.
It was more to the point that the ERRP in simple terms replaces days off under the old CAP371 rules e.g. 1 in 8 / 2 in 14 and 8 in 28. So under CAP when crew members sold their days off it was highly possible they would get days off in lieu as well as the $$ to maintain one or more of the days off requirements. Now though under EASA all you need is 36hrs and 1 local night to reset - This could be possible for example between a early and night. This now means that you could have a real run of work over 2 weeks and then you only need 60hrs and 2 local nights.
I doubt many UK airlines will roster this, and then if crew members sell $$$ the responsibility falls quietly on crew members responsibilites to manage their fatigue.
