Of all the acronyms in aviation, this must be the silliest… ATOMATOFLAMES? Surely you can\u2019t be serious!? I am serious and don\u2019t call me Shirley.<\/p>\n

It is difficult to remember all the regulations, rules, and procedures. But, it is not that difficult to remember a few acronyms that jog your memory<\/p>\n

ATOMATOFLAMES is one of the longest and most misunderstood acronyms commonly taught to student pilots. It is a list of instruments and equipment for flight according to FAR 91.205.<\/p>\n

 <\/p>\n

What is 91.205?<\/h2>\n

91.205 is the regulation for powered civil aircraft with standard category U.S. airworthiness certificates. Specifying the required equipment for aircraft operation.<\/p>\n

FAR 91.205 (b) is for visual-flight rules (day) and 91.205(c) is for visual-flight rules (night).\u00a0 91.205(d) is for Instrument flight rules, which requires everything in 91.205(b)and(c).<\/p>\n

Isn\u2019t FAA legal writing excellent? <\/em><\/p>\n

Like most FAA regulations it is important to know and understand these rules. However, it is more important to be familiar with and be able to apply the regulations to your operations. Just knowing an acronym is great trivia, but as you will see, it has many gaps and will not guarantee you are operating safely.<\/p>\n

What is ATOMATOFLAMES?<\/h2>\n

ATOMATOFLAMES is the acronym for VFR required equipment during day flight according to 91.205(b). It is often also referred to as \u2018Tomato Flames.\u2019<\/p>\n

ATOMATOFLAMES Acronym:<\/h2>\n

A \u2013 airspeed indicator<\/strong>
\nT \u2013 tachometer (for each engine)<\/strong>
\nO \u2013 oil pressure gauge (for each engine using a pressure system)<\/strong>
\nM \u2013 manifold pressure gauge (for each altitude engine)<\/strong>
\nA \u2013 altimeter<\/strong>
\nT \u2013 temperature gauge (for each liquid-cooled engine)<\/strong>
\nO \u2013 oil temperature gauge (for each engine)<\/strong>
\nF \u2013 fuel gauge<\/strong>
\nL \u2013 landing gear position indicator<\/strong>
\nA \u2013 anti-collision lights<\/strong>
\nM \u2013 magnetic compass<\/strong>
\nE \u2013 ELT<\/strong>
\nS \u2013 safety belts<\/strong><\/p>\n

This list is quite thorough, but also leaves many questions? Most students will notice that it doesn\u2019t include many aircraft parts. Do we need seats? What about wings? This list covers most of the practical instruments inside the cockpit. It is not intended to be the master list of every feature required in airplane manufacturing and design.<\/p>\n

Do I need to know this for my checkride?<\/h2>\n

Absolutely you do.\u00a0 Now, if you don’t have it memorized verbatim, that is okay, but you certainly need to know where to look (in the FARAIM 14CFR91.205) and be able to understand that text.\u00a0 If you’re not sure how to interpret the text in the FARAIM and apply it during your oral exam with the FAA, check out this video here.<\/a><\/p>\n
