Which item is not included in ARROW as a required document?

• A. Weight and Balance information
• B. Oxygen system
• C. Airworthiness certificate
• D. Operating limitations

Answer: (B)

ARROW is a checklist of documents you must have with you when operating a civil aircraft. It covers Airworthiness certificate, Registration, Radio station license (when required for international flights), Operating limitations, and Weight and balance information. The oxygen system is not a document you carry; it’s equipment that may be required for flight at certain altitudes, but it isn’t part of the ARROW set. So the item not included in ARROW as a required document is the oxygen system.
