Bilingualism in the Sky (ICAO’s Uniting Aviation)

“There are some 100,000 commercial flights each day in the world which means that literally millions of interactions take place between pilots and air traffic controllers. These very often take place in English – a foreign language for the vast majority. So how do these foreign-language discussions take place and how efficient are they? More importantly, are there breakdowns, and if so, what are they due to? And how can we make improvements?”
