The issue with EU-OPS is that it is not something that the UK CAA can chop and change locally. - Unlike JAR-OPS and JAR-FCL
Provided that operators comply with EU-OPS then the CAA can not make the requirements any different.
If local operators volunteer to do more and spend more then that is up to them.
I do wonder how long it is going to take the CAA post 2012 to adapt to simply being a stakeholder in the big scheme of things.
