Please would you let us know what the 'list of peeves' consists of so that we can do something about it?
I can well imagine that some low time pilots with JAR-FCL PPLs arriving in the US with the intention of wanting to drone up and down the coast 'hours building' would genuinely irritate their US instructors with a 'I've got my licence - I know it all' attitude. You have my sympathy!!
I too have met some low-hours folk who seem to think that there is nothing more for them to learn - all they have to do is to burn holes in the sky and the airlines will welcome them with open arms.....................
