# European aviation safety and pilot fatigue concerns > Developing situation record from CLSTR: https://clstr.news/situations/european-aviation-safety-and-pilot-fatigue-concerns > Updated: 2026-10-26T23:00:21.000Z. Sources: 49. Developments: 2. A survey of approximately 7,200 pilots conducted by the European Cockpit Association (ECA) has identified significant safety risks regarding fatigue in European aviation. The research found that 76.8% of respondents experienced at least one microsleep episode in the cockpit during the four weeks preceding the survey. The findings indicate systemic issues with fatigue management and reporting. More than one-third of pilots reported insufficient rest, and nearly 24% admitted to flying while too fatigued to work. Many pilots cited fear of management retaliation or a desire to avoid causing disruption as reasons for not officially declaring themselves unfit. Only 11.9% of respondents expressed trust in their airline’s fatigue reporting system. These fatigue concerns are compounded by broader industry challenges, including a documented increase in atmospheric turbulence. Data shows that severe clear-air turbulence has increased by 55% between 1979 and 2020, with projections suggesting further increases linked to rising global temperatures. ## Timeline ### 2026-10-26: Aviation industry faces rising turbulence and pilot fatigue risks Aviation safety is threatened by a 55% increase in severe clear-air turbulence due to climate change and widespread pilot fatigue, with many aviators reporting micro-sleep episodes. 3 sources. https://clstr.news/cluster/aviation-industry-faces-rising-turbulence-and-pilot-fatigue-risks ### 2026-10-26: European pilots report widespread fatigue and microsleep incidents A survey of 7,200 European pilots reveals that 76.8% experienced microsleeps in the cockpit, with many flying while fatigued due to fear of management retaliation. 46 sources. https://clstr.news/cluster/european-cockpit-association-report-reveals-high-pilot-fatigue-levels --- Cite as: European aviation safety and pilot fatigue concerns.
