ATOMATOEFLAMES is an acronym for a checklist of all the equipment required to operate an aircraft in the United States during the day under VFR conditions. All of these instruments or systems must be in the aircraft and functioning, at a minimum. Why is there such a mnemonic? Because you may be asked this on either your pilot's written exam or oral exam or both, and to help you remember what you need to fly legally and safely. This one is slightly superior to GOOSE A CAT because it contains instruments required on complex airplanes and those with liquid-cooled engines.
The actual 'official list' can be found in the U.S. Federal Aviation Regulations (FAR) or Title 14 CFR §91.205(b) and is more exhaustive and much harder to remember:
An emergency locator transmitter, if required by §91.207.
For normal, utility, and acrobatic category airplanes with a seating configuration, excluding pilot seats, of 9 or less, manufactured after December 12, 1986, a shoulder harness for—
- Airspeed indicator.
- Magnetic direction indicator.
- Tachometer for each engine.
- Oil pressure gauge for each engine using pressure system.
- Temperature gauge for each liquid-cooled engine.
- Oil temperature gauge for each air-cooled engine.
- Manifold pressure gauge for each altitude engine.
- Fuel gauge indicating the quantity of fuel in each tank.
- Landing gear position indicator, if the aircraft has a retractable landing gear.
- For small civil airplanes certificated after March 11, 1996, in accordance with part 23 of this chapter, an approved aviation red or aviation white anticollision light system. In the event of failure of any light of the anticollision light system, operation of the aircraft may continue to a location where repairs or replacement can be made.
- If the aircraft is operated for hire over water and beyond power-off gliding distance from shore, approved flotation gear readily available to each occupant and, unless the aircraft is operating under part 121 of this subchapter, at least one pyrotechnic signaling device. As used in this section, “shore” means that area of the land adjacent to the water which is above the high water mark and excludes land areas which are intermittently under water.
- An approved safety belt with an approved metal-to-metal latching device for each occupant 2 years of age or older.
- For small civil airplanes manufactured after July 18, 1978, an approved shoulder harness for each front seat. The shoulder harness must be designed to protect the occupant from serious head injury when the occupant experiences the ultimate inertia forces specified in §23.561(b)(2) of this chapter. Each shoulder harness installed at a flight crewmember station must permit the crewmember, when seated and with the safety belt and shoulder harness fastened, to perform all functions necessary for flight operations. For purposes of this paragraph—
- The date of manufacture of an airplane is the date the inspection acceptance records reflect that the airplane is complete and meets the FAA-approved type design data; and
- A front seat is a seat located at a flight crewmember station or any seat located alongside such a seat.
For rotorcraft manufactured after September 16, 1992, a shoulder harness for each seat that meets the requirements of §27.2 or §29.2 of this chapter in effect on September 16, 1991.
- Each front seat that meets the requirements of §23.785 (g) and (h) of this chapter in effect on December 12, 1985;
- Each additional seat that meets the requirements of §23.785(g) of this chapter in effect on December 12, 1985.
Other acronyms I've come across used to remember this information include GOOSE A CAT, AFASTMOOSE and ATOMSATOMS.
