Aviation jargon is sometimes a confusing and frustrating language and full three, four or more letter acronyms which can catch out even the knowledgeable! Sometime the picture is further confused by a single acronym having a number of meanings depending on the context in which it is used. Take for example the acronym IFE, it has several meanings depending on the area of aviation it relates to, it can mean 'In- Flight Emergency', 'In-Flight Entertainment' or 'International Flight Engineers'. Confused? Hopefully you won't be with the Jargon Buster you may be able to successfully navigate the multitude of meanings.
The listing is in alphabetical order for easier navigation. We hope it helps.
Of course the list is not exhaustive (though have tried to include most things). Please feel free to contact the IFALPA Communications Officer, if you would like to benefit others by adding (or taking away from) this list please contact
