Executive Summary

The Federal Office of Civil Aviation (BAZL) recorded nearly 15,000 incident reports in 2025 – an increase of approximately 20% compared to the previous year. The reports include aircraft scratches, incorrectly loaded aircraft, airspace violations, GPS disruptions, and conflicts between aircraft and drones. In commercial aviation, there were no fatal accidents; in recreational flying, four accidents occurred with six fatalities. The BAZL systematically analyzes this data to derive prevention measures.

The sharp increase in incident reports signals both positive and critical developments: an improved reporting culture documents heightened safety awareness, yet simultaneously the data reveals structural challenges such as growing air traffic, more complex airports with tighter space constraints, and new airspace conflicts caused by drones and GPS disruptions. For decision-makers in the aviation sector, prioritizing collision avoidance and modern surveillance technologies becomes central – particularly in the context of the FASST-CH project, which develops coordinated solutions across Europe.

Detailed Summary

The BAZL categorizes incidents into five areas: airports, air traffic control, flight operations, helicopters, and aircraft technology. The analysis reveals concrete risk factors: increased aircraft scratches, ground personnel moving incorrectly on more complex infrastructure, loading errors, and rising near-miss incidents in the air. Particularly notable is the increase in airspace violations due to new airspace structures as well as conflicts between different aircraft types – a sign of fragmented airspace utilization.

The main causes for the increase since 2019 are threefold: improved reporting culture (pilots and air traffic controllers report more proactively), growth in commercial air traffic, and widespread GPS disruptions in conflict regions. The BAZL derives prevention measures from these findings and works with the European Union Aviation Safety Agency (EASA) and the Swiss aviation industry on modern surveillance technologies. The "Staysafe.aero" campaign addresses pilots and light aviation stakeholders through weekly safety contributions on digital channels.

Key Messages

  • 14,972 incident reports in 2025: Significant increase compared to previous year; sign of improved safety culture and growing traffic complexity
  • No fatalities in commercial aviation: Safety measures show effectiveness; recreational flying and helicopter operations continue to record accidents
  • New risk factors: GPS disruptions, drone conflicts, more complex airports require modernized surveillance technologies and European coordination

Critical Questions

  1. Data Quality: How is it ensured that the 20% increase actually results from increased risks and not merely improved reporting willingness? What validation mechanisms exist for reports?

  2. Cause Attribution: The BAZL names three main causes (reporting culture, traffic growth, GPS disruptions). How is their respective share of the overall increase quantified?

  3. Implementation Speed: The FASST-CH project aims at modern surveillance technologies. What time horizon is realistic, and how are transition phases with higher collision risks managed?

  4. Recreational Flying Safety: While commercial aviation records zero fatalities, four accidents occurred in recreational flying. What targeted measures differ between the two segments?

  5. GPS Disruption Context: Are disruptions primarily limited to geopolitical conflicts (e.g., eastern airspace), or do they also occur in European and Swiss airspace?

  6. Drone Integration: How is the increase in drone conflicts addressed through regulation? Do separate airspace zones or tracking requirements exist?
