We pilots use all kinds of acronyms to remember stuff, because, like doctors and nurses, we have to memorize scads of information (SOI) and operate on people (OOP), sometimes removing their stomach contents for display all over the cockpit when we forgot to bring a bag.
We also use mnemonics or phrases, like, “Mary had a little lamb, her fleece was white as snow, and if the VASI’s red o’er red, I’m too blanking low.” Or, “High to low, look out below,” which means to not dork up your altimeter setting and remember to clear the area below the aircraft when dropping stuff.
