Take your own advice. When I'm in Dubai I follow proper comm procedures for Dubai and likewise for the US. Apparently you just do what you think is right.
Apologies if I was unclear - I am a Dubai ATCO - not much chance you'll find me flying around the Eastern Seaboard!
You seem to imply that it's ok to disregard the local rules because in the EU/Dubai that call is necessary.
No, I only work here so I adhere to the local requirements. Having worked in several very different countries, I can assure you that they are anything but standardised.
Apparently you just do what you think is right.
See above. As anyone who has worked in this part of the world for a significant period would confirm, I do what I am required to do by the local authorities and often more, as required by my own conscience.
