Definition
A document, supplied by the aircraft manufacturer, that itemizes the equipment installed in a specific aircraft at the time of delivery, including required, standard, and optional items. It is part of the aircraft's permanent records and is used to verify what equipment is installed and whether it is required for flight under the regulations and the aircraft's type certificate.
Plain English
A factory-supplied list showing exactly what equipment is fitted to your specific aircraft. It tells you what's on board and helps determine which items must be working before you fly.
Context Anchor
You may use the aircraft equipment list during preflight planning, a practical test, or any time you need to confirm what equipment is installed in the aircraft.
Derivation
Equipment comes from an older word meaning to fit out or prepare something for use, especially a ship. That helps here because the list is about what the aircraft is fitted with, not loose items someone happened to leave onboard.
Why Pilots Care
It confirms the aircraft meets equipment requirements and supplies the data needed for accurate weight-and-balance computations before every flight.
Intuition Check
Do not think of an aircraft equipment list as just any casual list of things in the airplane. In this context, it is an official aircraft document showing installed equipment for that specific aircraft.
Example Sentence 1
During the oral portion of the practical test, the examiner asked the applicant to find the aircraft equipment list and identify which installed items were required for day VFR flight.
Example Sentence 2
After adding a new ADS-B unit, the pilot updated the weight-and-balance using the revised aircraft equipment list.
