Review of Oxygen Requirements for Passenger Safety in Aviation

This report evaluates the oxygen provision requirements for passengers during flights, particularly in response to the JAR–OPS regulations. Proposals include changes to the supply of supplemental oxygen following decompression and recommendations for the provision of medical oxygen for passengers with health issues. The document discusses the history of the Oxygen Study Group (OSG), the medical evidence surrounding the safety of these proposals, and the industry's position on potential amendments. The report emphasizes the need for compelling evidence to ensure the safety of all travelers.

  1. Oxygen Study Group Report for OST 05 - 4 30 November 2005 Dr. Annette Ruge Aviation Health Unit, CAA UK

  2. OSG – The Requirements • JAR – OPS 1.760 First-aid oxygen • Proposal to provide oxygen for passengers who may need it during normal flight • JAR – OPS 1.770 Supplemental oxygen • Proposal to decrease oxygen provision after decompression between altitudes 15000 ft and 14000 ft from 30% of passengers to 10% of passengers

  3. History of OSG • 1999: Operations Committee installs OSG • October 2002: A-NPA OPS-32 (Oxygen) circulated for comments • April 2003: Comment-Response Document and amended proposal to EQSC. Decision not to launch a full NPA

  4. History of OSG • June 2003: Specialist Group • to evaluate the proposals and • provide evidence that proposals are safe • January 2005: Evaluation from 3 specialists received: Amended requirements may be safe for (young and) healthy passengers

  5. Proposed amendments ICAO & FAA • JAR – OPS 1.770 • is not ICAO compliant today • no plans to amend ICAO rule • the proposed amendments further decrease the provision for supplemental oxygen • existing JAR – OPS 1.770 is marginally lower than FAR 121.133 (e) (depending on aircraft type)

  6. OSG • OSG re-installed in OST 04-1 • No members from NAAs werenominated • UK view: Amend JAR – OPS 1.770 only if compelling medical evidence can be produced that the new provisions are safe for all occupants of an aeroplane

  7. OSG • AEA and Airbus nominated members • Industry view: • Circulate the proposals as they stand in A-NPA OPS 32 as full NPA • consider to restrict changes to certain routes (Greenland, Iran, Afghanistan), or • consider to grant exemptions for these routes as FAA does

  8. Medical Evidence • Most studies have been carried out in the 1930ies in the military • Opinions about safety vary because • the travelling public ages • passengers with medical conditions travel • even normal cabin altitude (8000 ft) is a medical problem for some passengers

  9. Options • Amend JAR – OPS 1.770 for specific routes • may be too complicated • (rules should be simple) • Grant exemptions as FAA does • compromises harmonisation in Europe • Continue without change

  10. Stabilisation Criteria for NPA activity • Any proposed change to conform with: • lead to a positive contribution to the JAA’s aim for safety; or • to correct an acute implementation problem; or • to align with the EU; or • to comply with IACO Annexes; or • to harmonise with FAA; or • to permit the rapid implementation of new technological processes

  11. The OST is asked to note that • there is no compelling medical evidence that the proposed amendments are safe for all occupants of an aircraft • medical evidence supporting the proposals does exist for healthy passengers

  12. The OST is asked to note that • the proposal in JAR – OPS 1.760 to carry medical oxygen may be of advantage for sick passengers • Industry is in favour of the proposed changes - or possibility of exemptions for specific routes - to regain a global level playing field

  13. The OST is asked to note that • the OSG did not achieve full consensus on the proposed amendments as outlined in A-NPA OPS 32 • the JAA criteria for a NPA are not met

  14. The way ahead • The OST is asked to agree on the way forward with the options: • to continue the work considering specific routes only; or • to consider exemptions from the requirements for specific routes; or

  15. The way ahead • The OST is asked to agree on the way forward with the options: • not to amend JAR – OPS 1.770 but consider changes to 1.760; or • not to amend the oxygen provisions in JAR – OPS

  16. Thank you
