What must be stored within the aircraft at all times and must be standardized, completed, and up-to-date?

• A. Pilot's log
• B. Maintenance manual
• C. Aircraft Information File (AIF)
• D. Flight plan

Answer: (C)

The key idea is that the Aircraft Information File (AIF) is the on-board, standardized set of documents and data you must have with the aircraft and keep current. This file ensures quick access to everything needed to fly legally and safely, and it’s kept up to date as changes occur. The AIF typically includes the aircraft’s airworthiness certificate, registration, weight and balance information, operating limitations, and the current approved flight manual or POH along with any applicable supplements or notices. Keeping this bundle in the aircraft in a consistent format means any pilot can verify legality, weight and balance, and applicable limits before flight without hunting through separate sources. The other items listed don’t serve the same purpose of being a complete, current on-board reference file: a pilot’s log is personal history, a maintenance manual is typically kept at the shop or depot, and a flight plan is filed and not required to be carried as a standard on-board document.
