correct. Since the US does allow non-US registered airplanes to land
in the US, does it make sense to follow international standards. Since
the AIM is not regulatory, it makes sense to conform to international
standards. Instead the FAA has decided to do as they see fit and
not give a damn about international standard. For this, I don't see
anything wrong with following international standard as international
aircraft can misunderstand the US phraseology. BTW, I've heard many
complaints from non-US pilot saying US pilots use way too much
non-international standard phraseology making it hard to understand
and dangerous for when US pilots fly abroad.
