VFR And IFR Equipment Requirements

| September 7, 2020 | By: Severe VFR
VFR and IFR Equipment Requirements Title Card

According to Part 91.205, for an aircraft to legally be able to operate under VFR or IFR it is required to have a minimum amount of equipment installed and operational. 


VFR Minimum Equipment Requirements For DAY VFR ATOMATOFLAMES Explanation graphic

A large group of instruments, widely remembered with the acronym A TOMATO FLAMES AF, is required for day VFR operations. 

Not everything listed is necessarily required. For instance, if your aircraft does not have retractable gear, you do not need a landing gear position indicator. 

Other items could include:

  • Temperature Gauges: Only required for liquid-cooled engines.
  • Manifold Pressure Gauges: Only required for altitude compensating engines.
  • Oil Pressure Gauges: Only required for engines using a pressure system.
  • Oil Temperature Gauges: Only required for air-cooled engines.

Additionally, aircraft may require duplicates of certain instruments. For instance, multi-engine aircraft are required to have the respective engine gauges for each engine. 

This means two manifold pressure gauges, two tachometers, two oil pressure get the idea. 

Other equipment that may require duplicates includes:

  • Fuel Gauges: One for each fuel tank 
  • Seat and Safety Belts: One for each seat

Note: While this regulation does allow aircraft made before specific dates and occupants under two years old not to require a safety belt, it is in the best interest of safety to have every passenger wear a seat belt.

If this regulation isn't hard enough, the requirements for anti-collision lights only applies to aircraft certificated after March 11, 1996

Lastly, there are certain exceptions to the emergency locator transmitter. However, this topic is worthy of its own discussion. You can read about ELT exceptions under 14 CFR 91.207

One thing the standard ATOMATOFLAMES acronym does not cover is flotation gear. That's why we suggest adding AF to the end of the acronym.

According to Part 91.205, if the aircraft is operated for hire over water and beyond power-off gliding distance, approved flotation gear for each occupant and a pyrotechnic device must be readily available. 

Night VFR

Night VFR Minimum Equipment Requirements FLAPS Acronym

For an aircraft to operate between evening civil twilight and morning civil twilight it must have all of the day vfr equipment installed plus additional equipment remembered with the acronym: FLAPS

As with the day VFR requirements, not all the listed equipment is necessarily required. 

For instance, if your aircraft has circuit breakers installed, you do not require any fuses. However, if your aircraft does have fuses installed, you must have either:

  • One complete set of fuses, or
  • Three replacement fuses for each type of fuse

Along the same lines, the requirement for a landing light is only required if you are flying for hire.

Finally, all aircraft are required to have an anti-collision system regardless of the aircraft's certification date. 

IFR Flight

IFR Minimum Equipment requirements GRABCARD acronym

To fly an aircraft under an IFR flight plan the pilot must be instrument rated and current. Additionally, your aircraft must have all the day VFR, and night VFR equipment requirements if flying at night, plus an entirely new set of instruments remembered with the acronym: GRAB CARD. 

Like every other equipment requirement, there are a few caveats to these equipment requirements. 

  • The generator or alternator must produce sufficient power for all electronic elements.
  • The radios must include a two-way radio and a navigational radio suitable to the route being flown.
  • The clock must be installed in the aircraft and display in HH:MM:SS format. 

Under VFR day equipment, an altimeter was listed. IFR equipment also requires an altimeter. However, to meet IFR requirements, the altimeter must be adjustable and sensitive to barometric pressure. A typical barometric altimeter satisfies this. GPS-based altimeters do not fulfill this requirement. 


Multi-Engine: Zero-Sideslip

The zero-sideslip is necessary for a pilot to maintain control of an aircraft and have the greatest climb performance during an engine failure in a twin.

An Emergency Locator Transmitter (ELT) is a battery-operated transmitter developed to locate a downed aircraft and is a component of the various emergency services available to pilots.
