Fatigue safety cases

A safety case is a structured argument, supported by evidence, intended to justify that a system is acceptably safe for a specific application in a specific operating environment (UK Defence Standard 00-56).

Clockwork Research has undertaken fatigue safety cases for aviation operators including easyJet, Qatar Airways, Air France and the Swiss Air Ambulance.

Operators undertake fatigue safety cases for different reasons, including:

  • as part of the FRMS, to explore in depth an aspect of the operation
  • to demonstrate to the regulator that an existing system of work is safe
  • to seek a derogation for work outside of flight and duty time regulations.

Clockwork Research is experienced in designing complex safety cases. Different types of data are collected but typically we utilise activity monitors to evaluate sleep and wake times, sleep and activity logs, psychomotor vigilance tests (PVT) and interviews.  We can provide all of the data collection equipment, undertake the statistical analysis and deliver a detailed report to an operator, for review by the regulator where applicable.

Titan Airways engaged with Clockwork to assist in the development of training to meet both the regulatory needs of EASA-FTL and the unique fatigue management challenges that we face in an ad-hoc operating environment. Clockwork’s approach to the task was methodical and also sympathetic to the diverse operation types we have. The communication from the Clockwork team was excellent throughout the project including ongoing support after release. The final training product truly combined the theoretical and practical aspects of fatigue management with the Titan operating environment and ethos.open quote

We have been working closely with Clockwork since 2013. They have been instrumental in the airline successfully setting up an effective fatigue programme, through an in-depth analysis of the airlines operations and produced excellent training materials to improve the crew understanding of fatigue. The staff at Clockwork are extremely knowledgeable and professional, making it easy to achieve good results in reducing the risks associated with fatigue in our very complex environment.open quote

We embarked on a complex project with Clockwork and the team at Clockwork were receptive to our ideas and made sure they immersed themselves in our own company culture. This relationship building gave us the ability to give open and honest feedback from both parties which resulted in an excellent programme that our cabin crew could use that was appropriate to their roles and easy to relate to.open quote
