Aviation English is the language of civil aviation.
“Aviation English is the language of civil aviation.”
It was a joke! I know, I’m a pilot.
Actually, some French speaking Quebecois get a bit touchy about being addressed in English. Also, the world over, in all languages, if one doesn’t want to comply with instructions given over the radio, ‘garbled transmission’ is sometimes blamed for lack of compliance.
Back when commercial airlines were ferrying troops to Vietnam, an airliner was flying south on final approach to DaNang Air Force Base. The air traffic controller, who was probably a young enlisted man, was trying to launch two Phantoms to the north on an urgent Close Air Support mission.
To get the airliner out of the way, the controller told him, “Give me a Right 360 degree turn now”.
The airline pilot responded, “i’ll have you know it costs my airline $200 every time we make a 180 degree turn”.
The controller shot right back at him, “Then give me $400 worth to the right, immediately!”
In this instance, who knows. It may have been genuine comm problems.
