The full ICAO report makes interesting reading. in the summary of the most common conditions reported by Pilots in which they identified confusion, especially when frequencies were busy, had a weak signal or static.
The lack of standardization in communications was the second most frequently mentioned condition and included reference to the use of slang, the use of a local holding area which was not on the airport diagram, improper usage of the phonetic alphabet (e.g., “Nectar” instead of “November”) and the use of call signs where ICAO standard terminology was not used. This condition was most commonly noted in communications within the US.
It's not just me.
