Thanks for your reply BigGrecian and I do agree with you, it's EASA rule. The thing is my colleagues from different NAAs (three different countries) hadn't this problem. Seems like that the only authority that cares about this briefing is UK CAA.
With only the UK, Hungary and Switzerland having implemented EASA this is why.
Wait till the other countries implement EASA and I think it will become similar across the NAAs.
