Hardly. Too often, however, it seems that if it's not done the british way, it's just not done right. Or so the brits would have us believe.
I am disappointed that you made such a petty comment, which does not align with the excellent input you usually give.
When flying in UK airspace, the UK rules apply to 121.5.
Pilots who do not respect the UK laws need education or if that does not work, punitive action.
I have flown in the USA and made a point of learning the FARs (by self study and formal training) and respecting the different ways things are done, even when they felt alien.
That was as a private pilot, I therefore have some trouble understanding why professional pilots cannot make themselves aware of the UK procedures and comply with these.
