Risk Management

Fatigue Risk Assessment Methodologies, by Cpt. Kristjof Tritschler

The Fatigue Factor Assessment and Mitigation Table is proposed as a fatigue-specific risk assessment methodology for a particular duty or work pattern. This methodology is based on internal scientific studies, relevant scientific literature, internal surveys and FRMS experience. The methodology starts by identifying the root causes of fatigue and provides effective mitigation measures.

Fatigue Resource Library

FRMS Forum

The FRMS Forum has been created by the international aviation industry to help member organisations with their approach to introduce a Fatigue Risk Management System into their airlines. They provide free access to resources including: presentations, templates, case studies, notes, regulations and guidance documents.

Fatigue Risk Management Programme (Word)

This example is a working document used in the helicopter and agricultural aviation sectors. If submitted as part of an application for certification of an aviation operation, it would need to be assessed on a case-by-case basis by the CAA .

 NPA No. 25/2014 CAR PART IV CAR-OPS1 - Commercial & Private Air Transport (Aeroplanes) The GCAA has recently conducted a review of CAR-OPS 1 Regulation on the basis of ICAO Annex 6 Part 1 SARPS, Alignment with EASA and international standard practices. See in particular subpart Q and note on page 290: unless otherwise notified, this regulator uses CAA UK CAP 371 as a basis for UAE regulatory consideration of operator fatigue management schemes. Some of the material in subpart Q comes directly from the ICAO guidance material.

Aerospace Medicine Technical Reports: 07/21 Flight Attendant Fatigue The report contains a literature review on fatigue as potentially experienced by flight attendants, an evaluation of currently used (actual vs scheduled) flight attendant duty schedules, and a comparison of these schedules to the current CFRs. The report additionally reviews fatigue-related incident/accident information from the Aviation Safety Reporting System (ASRS) and the NTSB database.

Fatigue Risk Management Fatigue information that applies to aviation maintenance personnel. This is the result of a multi-disciplinary expert work group, which investigated the issues associated with human fatigue in maintenance and the practical science-based methods that can be used to manage fatigue risk.

Learning From Occurrences

Insights into how fatigue can contribute to incidents and accidents, and lessons to be learned from these events.

NASA Aviation Safety Reporting System (ASRS)

ASRS’s monthly safety newsletter CALLBACK presents excerpts from de-identified ASRS reports with supporting commentary in a “lessons learned” format. It also contains ASRS research studies and related aviation safety information. Issue 438 has several fatigue case studies.

National Transportation Safety Board (NTSB)

The NTSB’s Most Wanted List represents the NTSB's advocacy priorities. It is designed to increase awareness of, and support for, the most critical changes needed to reduce transportation accidents and save lives. The 2016 list features the reduction of fatigue-related accidents as a top priority.

The Final Report (PDF 2.39 MB)  determined the most probable cause of the accident to be flight crew fatigue; the crew exceeded flight duty times and suffered from the effects of prolonged wakefulness.

Jeppesen Fatigue Data Collection Project

Jeppesen is starting a new industry-wide fatigue data collection targeting crew with larger circadian disruptions. This new research project, focused on acclimatisation, is starting in April 2016 with data collection performed during August and September.

We are now looking for organisations and individuals that regularly operate across larger time-zone transitions with long periods out-of-base.

If you are interested in participating, please consider registering through this link and we will provide further details on methodology, tools, crew recruitment, and e-learning material. Participation is free of charge. All data is kept confidential and fed back to participating organisations.

CAA 2006 Workshop

A workshop was held in June 2006, bringing together experts from industry and academia, as well as CAA personnel. The workshop’s recommendations are contained in the Workshop Notes. Progress on the recommendations and meeting updates were tracked in an Action Register.
