    Very interesting, got 7 out of 12 and since I have not heard of most of these that’s pretty good for me but I learned about the ones I did not know.
    Thanks for the info. This was a teaching moment.

    Acronyms are useful in saving time and space, but only in context — obviously different fields of expertise or occupations may use the same acronyms with entirely different meanings (ask the military types what MOS means!). Anyway, I appreciate the time and effort to put together the quiz.

    I agree with the first comment. These acronyms are stupid as is trying to read a navigation chart through a soda straw or a 6by9 screen while worrying if the battery that powers it will run out of charge.

    Received a 9/12, mostly by process of elimination. However,
    if a pilot does not know what PAPI is then go to the nearest
    FAA office and turn in your era. Also, never even drive by an
    airport….never!

    The more involved you are with flying the more you tend to use acronyms. I’m going to say ADS-B or TIS or AHARS ( “A-HARS”) to my avionics shop. I’m going to hear PAPI or RAIM from a sim instructor.

    I did get 12/12, but then again, I’d better have, I’m a CFI! But for those wondering why/purpose of acronyms, well, these are just tools in our tool bag of aviation, and like any tool, it’s a good thing to know how to use it and when you need it. It’s our “language.” And true, this is what these acronyms mean in aviation, and they could mean something entirely different in another field, but aren’t there an awful lot of words in our English language like that? Same word, completely different meaning?! This is what also makes aviation so fun and challenging…always something new to learn!

    11 out of 12. Great idea to challenge and test us to affirm and/or learn acronyms that are used by pilots and ATC.

    I got 11 out of 12 but I also the acronyms are over used. That being said, it’s the way of aviation so it’s best to know them as much as possible.

    Thanks, great quiz and refresher…..more than just figuring out the acronyms, this got me into some new areas in the iPad and Foreflight, something I should do more of!
    p.s. Loved Kathy’s response to D H above!

    Well took the quiz and got 7 out of 12 not bad for a rusty pilot as I am. Need to brush up for sure before heading back out into the skies! Terminology has changed so much over the past 20 years it is remarkable.
