AGARD - Multilingual Aeronautical Dictionary, Acronyms and Abbreviations

Source: https://ia800102.us.archive.org/0/items/DTIC_ADA095571/DTIC_ADA095571.pdf

(This is just a quick/dirty extraction! I'll upload a cleaned up version at some point.)

‘The abbreviations and acronyms listed in this section are some of the more common ones used in the context of aeronautics and include those used in the definition section of this dictionary. The list includes name acronyms, affiliation acronyms and abbreviations, agency acronyms and abbreviations, etc., which may be useful in reading this dictionary. Note that the same abbreviation or acronym may indicate more than one definition and these are separated by a semicolon.’
