NOSS is an adaptation of the Line Operation Safety Audit (LOSA) methodology, which was developed by The University of Texas Human Factors Research Project (UTHF) in consultation with numerous airlines and ICAO. The LOSA methodology is recognized worldwide and is formally endorsed by ICAO, IATA, the FAA, IFALPA, and ALPA. Over 90 airlines worldwide have deployed LOSA to inform their safety management systems.
As a result of the safety benefits that airlines have experienced from LOSA, ICAO established a formal Study Group comprised of Air Navigation Service Providers (ANSPs) and aviation safety experts from around the world to develop a means to collect safety data during everyday air traffic operations, which resulted in NOSS. The NOSS Collaborative, then part of the University of Texas, provided methodological guidance as a member of the ICAO NOSS Study Group and facilitated early field trials. The success of these field trials led to the development of the ICAO NOSS Manual (Document 9910 AN/473).
To date, the NOSS Collaborative has worked with ANSPs in Australia, Canada, Hong Kong, Ireland, New Zealand, South Africa, South Korea, Thailand, Trinidad & Tobago, the United States of America, and the United Arab Emirates to implement NOSS or other TEM related programs. This has led to an Archive of over 5,000 NOSS observations from a wide range of operational environments that allows for de-identified benchmarking with comparable facilities.
The NOSS Collaborative is the principal provider of NOSS and TEM information and implementation in the air navigation domain. Our primary charter is to aide ANSPs in NOSS implementation. Our broad exposure to numerous ANSPs – in a wide range of operational environments and cultures – provides us with the expertise to ensure you have a successful NOSS. We also provide de-identified benchmarking with similar facilities that have worked with the NOSS Collaborative.
The NOSS Collaborative was established by Dr. Chris Henry during his time as a graduate student at the University of Texas at Austin. After assisting his colleagues on projects in the flight operations domain, Dr. Henry was nominated by ICAO to serve as technical and methodological expert in the development of NOSS. He has been working with ANSPs to implement NOSS since then.
Though the NOSS Collaborative spends most of its time refining and implementing NOSS, it does devote time to other activities, including the application of TEM to incident investigation programs, check and training programs, and mining the NOSS Archive to research developing safety trends. The NOSS Collaborative has also advised several ANSPs in developing internal TEM and human factors training programs. The NOSS Collaborative is excited to continue working with its partners and other industry leaders to further evolve emerging safety techniques.
