ICAO 2024 Safety Performance: What the Data Shows
The ICAO Global Aviation Safety Report 2024 highlights civil aviation safety trends across 2019–2024 and provides a detailed snapshot of 2024 accident data. With global passenger demand recovering strongly — 4.528 billion passengers in 2024, up 8.6% from 2023, and 37.09 million departures (+5.2%) — the report presents a concerning picture: the accident count increased to 95 (up 43.9% from 2023), with the accident rate rising to 2.56 per million departures from 1.87 in 2023. The 2024 snapshot includes 10 fatal accidents, 296 fatalities, and 134 serious injuries.
The key message for operators, regulators, and aviation service providers is clear: traffic growth must be matched by stronger safety assurance, evidence traceability, and audit-ready implementation. The relationship between increasing exposure and accident frequency is a direct call to action for organizations to strengthen their aviation safety management systems and compliance monitoring frameworks.
Frequency vs. Severity: Understanding the 2024 Risk Profile
High-frequency events (accident count drivers):
Turbulence (TURB) and Abnormal Runway Contact (ARC) together accounted for more than 50% of all 2024 accidents by count. Ramp and ground handling events contributed a medium share. These categories drive high accident numbers but vary significantly in severity outcome.
High-severity events (fatality drivers):
Loss of Control In-flight (LOC-I) and bird strikes together accounted for more than 80% of fatalities in 2024. Turbulence was responsible for approximately 75% of all serious injuries. This frequency-severity split confirms that effective SMS must prioritise both high-frequency prevention (turbulence, runway contact, ground operations) and high-severity barrier management (LOC-I, CFIT, bird strike mitigation).
Emerging Safety Risk Areas:
The 2024 report identifies several emerging risk categories requiring proactive attention: GNSS interference (jamming/spoofing) requiring contingency procedures and coordination; turbulence management including forecasting use, cabin SOP discipline, and injury prevention; runway safety including incursion/excursion prevention; wildlife strike risk controls; RPAS/Advanced Air Mobility integration with ATM; GADSS position reporting requirements; and SMS evolution toward stronger evidence traceability and safety assurance capabilities aligned with ICAO Annex 19, 3rd Edition.
What Operators Should Do Now
Strengthen high-severity controls: LOC-I prevention programmes, crew training effectiveness assurance, and CFIT/GPWS system utilization should be reviewed against current best practice and IOSA standards. The 2024 data confirms that these categories remain disproportionately responsible for fatal outcomes.
Reduce runway and ramp events: Process control, competency oversight, and internal audit quality for ground operations and aircraft handling should be reviewed. Ground handlers with ISAGO registration should assess whether their SMS is operationally active in identifying and mitigating ground operation hazards.
Improve turbulence defenses: Cabin crew procedures, passenger injury prevention protocols, turbulence forecasting utilization, and incident reporting quality all require review. Turbulence-related serious injuries now represent approximately 75% of total serious injury events globally.
Build GNSS resilience: Contingency procedures for GNSS degradation, crew training on RAIM and navigation reversionary procedures, and route and operational planning inputs should be reviewed as GNSS jamming and spoofing events continue to increase in frequency globally.
Upgrade evidence traceability: The complete hazard-to-control-to-assurance-to-performance chain must be documented and demonstrable. The 2024 ICAO data reinforces that organizations with robust internal audit systems, evidence libraries, and corrective action closure mechanisms are better positioned to respond to both audit requirements and real operational safety challenges. Aero Support Group supports organizations with structured compliance and audit readiness programmes aligned with ICAO, IATA, EASA, and national authority requirements.
Regulatory alignment for IOSA, ISAGO, and compliance frameworks:
The accident data categories identified in the ICAO 2024 report directly map onto areas assessed by IOSA ISARPs (flight operations, SMS, CFIT/LOC-I barriers) and ISAGO standards (ground operations, ramp safety, GSE management). Organizations preparing for IOSA renewal or ISAGO audit cycles should use the 2024 risk profile to prioritize their gap assessment activities and target their corrective action resources at the highest-risk operational categories.

Conclusion
The ICAO Global Aviation Safety Report 2024 confirms that aviation safety performance cannot be assumed from traffic growth or regulatory compliance alone. The 43.9% increase in accident count alongside continued growth in operations is a clear signal that organizations must invest in stronger safety assurance, evidence-based management review, and operational discipline — not just documentation compliance. Aero Support Group supports airlines, MROs, ground handlers, airports, and civil aviation authorities with the consulting expertise to translate ICAO safety data into practical, audit-ready compliance and safety management improvements.
The ICAO 2024 report found that the global accident rate increased to 2.56 per million departures (from 1.87 in 2023), with 95 total accidents (+43.9% vs 2023). There were 10 fatal accidents and 296 fatalities. Turbulence and Abnormal Runway Contact drove the highest accident counts, while LOC-I and bird strikes accounted for over 80% of fatalities.
The 2024 accident rate increase reflects both a higher absolute number of accidents and increasing operational exposure from strong traffic recovery. As departure volumes grow, risk exposure increases — and where safety assurance and operational discipline do not keep pace with growth, accident rates tend to increase. The ICAO data reinforces the need for proactive safety management and continuous improvement, not just post-event investigation.
Loss of Control In-flight (LOC-I) and bird strikes together accounted for over 80% of fatalities in 2024. Turbulence accounted for approximately 75% of serious injuries. These categories should be priority focus areas for airlines reviewing their SMS hazard identification, risk controls, and barrier effectiveness.
Key emerging risks identified include GNSS interference (jamming/spoofing) requiring contingency procedures; turbulence management and passenger injury prevention; runway safety (incursion and excursion prevention); wildlife strikes; RPAS/Advanced Air Mobility integration; GADSS position reporting; and the ongoing need to strengthen SMS evidence traceability and safety assurance in line with ICAO Annex 19 (3rd Edition).
Operators should use the ICAO 2024 risk profile to prioritize their SMS gap assessment activities and target corrective action resources at the highest-risk operational categories. LOC-I, CFIT, turbulence, and runway/ramp events identified in the data directly map onto IOSA and ISAGO audit areas — making the ICAO report a valuable input to pre-audit readiness planning and safety performance review cycles.
- Strengthen LOC-I prevention: crew training effectiveness, GPWS/TAWS systems, and stabilised approach enforcement
- Reduce runway and ramp events: process control, ground operations audits, and competency oversight
- Improve turbulence defenses: forecasting utilization, cabin procedures, and injury prevention protocols
- Build GNSS resilience: contingency procedures, crew training, and route planning for interference environments
- Upgrade SMS evidence traceability: hazard → control → assurance → performance → management action chain
- Align IOSA and ISAGO preparation priorities with 2024 accident category risk profile
