FlySentinel system is a unique, highly advanced state-of-the-art solution for monitoring both human and environment parameters. Implementation of this system allows you to identify, notify and prevent potential in-flight risk situations.

WHY?

As many recent studies show, pilot acute health issues (such as low oxygen saturation) and pilot fatigue may represent an underappreciated but potentially a major cause of flight accidents and therefore represent a major problem in aviation. Focusing on pilot fatigue majority of pilots acknowledges fatigue as a major problem and report to be fatigued due to their work. Factors that may cause this are: sleep loss, circadian rhythm disruption, cabin noise, vibrations, pressure changes, long working hours, crossing of time zones, irregular duties, night flights, jet-lag etc.

Persistent fatigue can cause many problems, such as impaired performance during work, decreased short-term memory, slowed reaction time, increased errors of omission, chronic health problem and decreased work-private life balance. For this reason it is important to detect fatigue among pilots early enough, before an incident or an accident occurs.

Currently there are no monitoring systems commercially available to monitor, detect and react to in-flight pilot vital signs (most importantly oxygen saturation) and pilot fatigue.

BENEFITS OF FLYSENTINEL IMPLEMENTATION

The flySentinel and EEG monitoring derived data will enable estimating pilots’ physiological condition, differentiating stages of pilot fatigue, establishing potential fatigue dynamics  and patterns etc.

HOW?

Active commercial pilots are continuously monitored over a specified period of consecutive on-duty days. Study parameters are measured continuously or at prespecified time points of the flight (Figure 1).

Pilot fatigue will be measured using single-channel EEG recording system. A single electrode is placed on the pilot’s head to noninvasively and continuously record pilot’s brainwave activity. Detected difference in primarily alpha brainwave activity is used to estimate pilot’s fatigue / alertness / drowsiness using a verified regression model that produces fatigue score. This score will in turn be used in further data analysis. This system has already proved useful in professional operators of heavy machinery (quarries) and in truck drivers. However no such system has yet been implemented in pilots.

Pilot’s physiological parameters will be measured using flySentinel monitoring device and system. The flySentinel compact monitoring device that is positioned on pilot’s wrist to nonintrusively measure the following parameters:

-blood oxygen saturation

-Pulse

-body temperature

-evironmental parameters such as cockpit temperature, humidity, noise, G-force and carbon monoxide.

Data management and analysis

During the flight all data is stored on the flySentinel device and dedicated tablet that will record brainwave activity data and results from psychological tests. After landing all data will be uploaded to a secure server for further analysis. FlySentinel data will be available to pilots at all times during the flight. However pilots will be blinded to fatigue data and data from psychological tests as this may result in significant bias of their self-fatigue perception.

At the end of the study all study participants will have access to all of their recorded data and the subsequent results.
