Oh? Genius (is that better?)?
Much, thanks. Your recognition, however, isn't necessary...nor particularly of any great value.
So when I'm flying over France and given an altitude assignment in French because they didn't extend me the "courtesy" to give me the clearance in English, ICAO is cool with that?
Are you an international operator? Per ICAO convention, English is spoken for international operations.
Whereas no country is obligated by law to adhere the Convention, following the Annexes is a courtesy. Not a legal requirement. That all signatory nations do so is an act of grace, not a legal mandate based on international law. An act of grace by nature is, therefore, courtesy.
Whether ICAO is "cool" with something or not is not particularly relevant to the topic. You stated in error that ICAO demands that all nations speak English in aviation operations, when conversing with English speakers. This is untrue, and represents a gross misunderstanding of the Annexes (Particularly 2, 5, 10, and 11).
When you operate internationally, the French will always communicate with you in English. Have you ever had them refuse a clearance because you want it in English? You could say you have, but then you would be lying.
You clearly implied ad nauseum that English is a "courtesy" in international operations.
So I did, but I didn't imply; I stated it directly, because it's a fact.
Adherence to the Convention is an act of courtesy, not obligation. Participation is voluntary by all signatories of the Convention, which did so of their own volition, and not under any international pressure of law. To support, maintain, and adhere to the Convention and it's annexes is therefore a matter of courtesy.
To demand, as numerous posters here have done, as quoted above, that English be spoken outside of the Convention is both egotistical and gregarious; such thinking is arrogantly stupid. To suggest that operations in foreign countries should be conducted in English in all cases, not simply international operations, is unrealistic, and utterly ridiculous.
While France and all other signatories conduct international operations in English as a courtesy to their participation in the ICAO convention, none are obligated to make all radio calls in English, particularly local domestic flights. Accordingly, in every country you will hear radio traffic in their native tongue; this is not in violation of the Convention or any annex, and is right and proper.
Those Ugly Americans who would have it otherwise, speak out of turn.
You would be one of the Ugly Americans...and the 95%, otherwise known as the "wet salt" crowd.
