Fatigue Risk Management

SOS has developed and can integrate a customized comprehensive fatigue risk management system. We have tools that are proven, scientifically sound and simple to use.

SOS has a biomathematical predictive fatigue model that is used in preflight planning and can also be used to evaluate a shift schedule and/or line schedule. SOS also offers turn-key ability to do fatigue studies for maintenance technicians and for flight crew. With all that information gathered, it makes the tools more relevant because customer specific data is used for the calculations instead of the industry-at-large data.

The fatigue prediction tool can be scaled up to evaluate a shift work schedule and a pilot’s line and scaled down to determine individual, acute fatigue for a given shift schedule or complex flight duty period. It is designed to be effective and reasonably accurate for short runs of days, compared to the scientifically proven biomathematical models. Our prediction model is good enough for risk management and endorsed by USAIG as a comprehensive FRMS solution.

We are now able to offer a comprehensive schedule analysis to include a predictive fatigue state, with daily sleep debt and acute sleep deprivation factors, and correlate that predictive fatigue state to a probability of a fatigue incident happening at any time along that schedule time run. The fatigue incident risk (FIR) is a calculated, mathematical expression of a probability akin to the probability in the risk matrix derived from FAA, ICAO and EASA publications. The added benefit to the customer is this expression, which shares not only a common language with the community of aviation regulators but also a common language of loss mitigation spoken by insurance companies and industrial officers worldwide.
