Where can you find oxygen duration tables?

Oxygen duration tables are essential for flight crews to determine how long the supplemental oxygen will last under specific conditions during an emergency. These tables are typically found in resources that are focused on flight operations and emergency procedures.

The correct choice identifies that these tables can be located in the Quick Reference Handbook (QRH) Volume 1 or the Flight Crew Operations Manual (FCOM) Volume 2. The QRH is a critical tool for pilots, providing quick access to information needed during abnormal or emergency situations, which includes oxygen usage. The FCOM provides operational information that assists flight crews in making informed decisions during a flight, including detailed procedures about the use of oxygen systems.

The other options, while relevant to aircraft documentation, do not specifically provide the information needed regarding oxygen duration. The Aircraft Operations Manual may cover general operational guidelines, but not necessarily the specifics on oxygen duration tables. The Flight Crew Handbook offers operational guidance but is less focused on detailed emergency procedures compared to the QRH and FCOM. The Maintenance Manual is intended for aircraft maintenance personnel and would not contain operational data relevant to flight crew performance or emergency procedures. Thus, the information about oxygen duration tables being found in the QRH or FCOM is crucial for pilots’ preparedness during emergencies.
