When starting with a new course, back in my instructing days, I would advise that the scourge of aviation was the uneducated use of abbreviations and acronyms and that, therefore, I would expect all students to question any abbreviation or acronym I used that they did not know. As incentive I would ask the meaning of any unquestioned abbreviation or acronym after the third use in my lessons. Always took a couple of lessons before they got into the swing of things.
Late in my career one of my subordinates complied a list of aviation acronyms and abbreviation from a number of sources. Many different meanings and uses in a 300 page document I still have on file.
In the Census question on language I always tick "other" and write in "Aviation.
Now, here's a challenge: Compose a single sentence using "ATM" three times with different meanings.
