Moreover I'm going to insist in communicating in very long words and challenge them to understand me
A lot of domestic US pilots and many of their ATCO's might have English proficiency, but they sure don't use standard RT procedures!
Thanks for the update and link Socal. I like the bit "the cost to the airman will be $2". It's the first thing I will have paid to the FAA for my licences and yet I've thrown hundreds, if not thousands, into the CAA for the same services!
