Communication is language.
But it is not a question of idioms - English, or Spanish, or French...!
Communication can be of NO problem between people of different languages.
The problem is often "social" -
Manner in which you address yourself to others.
It is a question of culture.
You may communicate well, but you might infringe on social traditions.

In aviation, crew interaction is derived from the anglo-saxon world.
It does not get across very well with people of other cultures.
Think of Japanese social rules. How does a F/O gives advice to his captain...?
My airline culture is from USA, and so is my English language, from USA.
But, I sometimes flew with British crews, was not always easy.
Not only different vocabulary, although using English.
South America is different, much the same as my original French culture.

Aviation is a rather exact science, with formulaes and strict rules.
But psychology is not an exact science. We are all different people.
I am flexible, and adaptable, anywhere, anyplace, anytime...
Some pilots are NOT. Some captains want it THEIR WAY.
And is it not that reading Pprune is quite an education to all of us...?
