EU operators have to obey both EU-OPS and foreign national law. It is not a question of either/or.
That's what I think also.
Let's now make a practical exercise.
In the States, for example, one has to declare emergency when reaching the 45 minutes minimum fuel. However, by EU-OPS 1.255, the Fuel Reserve is only 30 minutes. When does an EU registered aircraft have to declare emergency? When reaching the 45 or the 30 minutes minimum fuel status? i.e., can we plan to fly to the States, with only 30 minutes of reserve fuel?
