How AI Predicts Aircraft Defects Before They Become Fatal

How AI Predicts Aircraft Defects: How Big Data Makes the Skies Safer

Every day, over 100,000 commercial flights take to the skies worldwide, carrying millions of passengers who trust that their aircraft is safe and well-maintained. Behind this remarkable safety record lies an invisible revolution: artificial intelligence and big data analytics are transforming how airlines predict and prevent aircraft defects before they become critical safety issues. Traditional maintenance schedules relied on fixed intervals and reactive inspections, but modern aviation safety now leverages machine learning algorithms that analyze vast streams of sensor data to detect anomalies that human inspectors might miss.

Consider this: a single Boeing 787 generates approximately 1,000 gigabytes of data per flight—information about engine performance, hydraulic pressure, temperature fluctuations, and thousands of other parameters. **AI systems can process this enormous data volume in real-time, identifying patterns that signal potential component failures up to 30 days before they occur

**. This data-driven approach represents a fundamental shift in aviation safety, moving from “fix it when it breaks” to “prevent it before it fails.” The implications extend far beyond cost savings—predictive maintenance powered by AI and big data is literally saving lives by keeping defective components grounded before they can cause in-flight emergencies.

What Makes Aircraft Maintenance So Critical for Flight Safety

Aircraft maintenance is not merely a regulatory requirement—it represents the cornerstone of aviation safety in an industry where even minor defects can have catastrophic consequences. The complexity of modern commercial aircraft, which contain over 6 million parts in a typical wide-body jet, creates countless potential failure points that maintenance teams must monitor continuously. According to the FAA, approximately 80% of aircraft accidents are caused by human error, with a significant portion of these incidents involving undetected mechanical issues that maintenance systems failed to identify.

Traditional inspection methods rely heavily on visual examinations, scheduled component replacements, and reactive repairs after problems manifest. However, this approach has inherent limitations: human inspectors can overlook hairline cracks in critical components, scheduled maintenance may replace parts too early (wasting resources) or too late (risking failure), and reactive repairs mean aircraft are grounded unexpectedly, disrupting operations. The aviation industry recognized that a more proactive, data-driven approach was essential to enhance flight safety while improving operational efficiency. This realization sparked the integration of AI prediction and machine learning technologies into predictive maintenance systems, fundamentally transforming how airlines ensure their fleets remain airworthy.

How Big Data Transforms Aviation Safety Through Data Analysis

Big data in aviation encompasses the massive volumes of information generated by aircraft sensors, maintenance logs, flight operations, weather conditions, and historical performance records. Modern commercial aircraft are equipped with thousands of sensors that continuously monitor everything from engine vibration patterns to cabin pressure fluctuations, creating an unprecedented data stream for analysis. What makes this data truly powerful is not its volume alone, but how machine learning algorithms can identify subtle correlations and patterns that predict potential failures. For example, a slight increase in engine oil temperature combined with minor vibration changes and a specific flight altitude pattern might indicate an impending bearing failure—a connection too complex for traditional analysis methods to detect.

The transformation occurs through several technological layers: first, data collection systems aggregate information from multiple sources in real-time; second, cloud-based storage platforms provide the infrastructure to retain years of historical data for comparison; third, advanced analytics engines process this information using statistical models and AI algorithms; finally, predictive maintenance platforms translate these insights into actionable recommendations for maintenance crews.

Airlines like Delta and Lufthansa have implemented comprehensive big data systems that analyze flight data from their entire fleets, creating baseline performance profiles for each aircraft type. When an individual aircraft’s data deviates from these established patterns, the system automatically flags it for inspection. This data-driven approach has enabled airlines to shift from reactive maintenance (fixing problems after they occur) to predictive maintenance (preventing problems before they happen), dramatically improving both aviation safety and operational efficiency.

The Role of Machine Learning in Aircraft Defect Detection

Machine learning represents the computational intelligence that transforms raw aircraft data into predictive insights about potential defects and maintenance needs. Unlike traditional rule-based systems that follow predetermined logic, machine learning algorithms learn from historical patterns and continuously improve their predictions as they process more data. The most effective predictive maintenance systems employ multiple machine learning techniques simultaneously: supervised learning algorithms train on historical failure data to recognize warning signs; unsupervised learning identifies anomalous patterns that don’t match normal operational profiles; and reinforcement learning optimizes maintenance scheduling recommendations based on outcomes.

Consider how these systems work in practice: engineers first train the AI model using years of historical data that includes both normal operations and actual component failures. The algorithm learns to recognize the subtle data signatures that precede different types of defects—perhaps a specific pattern of temperature fluctuations always appears 72 hours before a hydraulic pump fails, or certain vibration frequencies indicate developing cracks in turbine blades. Once deployed, these trained models continuously analyze real-time data from operational aircraft, comparing current performance against learned patterns. When the system detects data signatures matching known pre-failure patterns, it generates maintenance alerts with specific probability scores and recommended inspection timeframes.

Advanced implementations use ensemble methods that combine predictions from multiple algorithms, improving accuracy and reducing false positives. Boeing’s Airplane Health Management system, for instance, employs neural networks, decision trees, and support vector machines simultaneously, cross-validating predictions to ensure reliability. The continuous learning aspect is crucial: as maintenance teams respond to predictions and document actual findings, this feedback loops back into the system, refining the algorithms and improving future predictions.

Cost Reduction and Efficiency Gains Through AI Prediction

The financial and operational benefits of AI-powered predictive maintenance extend far beyond simple cost savings—they represent a fundamental transformation in how airlines manage their fleets and resources. According to Boeing’s 2023 Statistical Summary, predictive maintenance using AI and big data analytics can reduce aircraft maintenance costs by 25-30% while improving safety outcomes. This remarkable improvement stems from multiple factors working in concert to optimize maintenance operations and resource allocation.

The underlying mechanisms driving these cost reductions involve several interconnected elements. First, predictive systems eliminate unnecessary preventive maintenance by replacing components based on actual condition rather than arbitrary time intervals. Traditional maintenance schedules might require replacing an expensive component every 5,000 flight hours regardless of its actual state, but AI analysis can determine if that specific component could safely operate for 6,500 hours, saving both the component cost and labor.

Second, early defect detection prevents cascading failures where one faulty component damages related systems, avoiding exponentially more expensive repairs. Third, predictive scheduling allows airlines to coordinate maintenance during already-planned downtime rather than grounding aircraft unexpectedly, preserving revenue-generating flight schedules. Fourth, optimized inventory management means airlines stock parts based on predicted needs rather than maintaining excessive inventories “just in case.”

Leading airlines have implemented predictive maintenance with impressive results: Delta Air Lines deployed their Flight Weather Viewer system that combines weather data with aircraft sensor information, predicting maintenance needs related to environmental stress. The system analyzes how specific weather conditions (turbulence, temperature extremes, moisture) affect different aircraft components, scheduling preemptive inspections after particularly stressful flights.

Singapore Airlines integrated Airbus’s Skywise platform, which aggregates data across their entire A350 fleet, identifying component reliability patterns and optimizing replacement schedules. Their implementation process involved three phases: initial data infrastructure setup (6 months), algorithm training and validation (4 months), and full operational deployment (3 months). Lufthansa Technik developed AVIATAR, a digital platform that monitors over 1,000 parameters per aircraft, providing maintenance recommendations that reduced unscheduled maintenance events by 35% within the first year of implementation.

Preventing Catastrophic Failures Before They Occur

The most critical value of AI prediction in aviation lies not in cost savings but in its ability to prevent catastrophic failures that could endanger lives. A study by McKinsey & Company found that airlines using predictive maintenance technologies experience 30-50% reduction in unscheduled maintenance events and up to 20% decrease in overall maintenance costs, but more importantly, these systems have prevented numerous potential in-flight emergencies by identifying critical defects during ground operations.

The progression from data detection to failure prevention involves sophisticated analytical processes that operate continuously. Modern aircraft generate sensor readings every few seconds across thousands of monitoring points—engine parameters, structural stress indicators, electrical system performance, hydraulic pressure variations, and avionics health checks. Machine learning algorithms establish baseline performance profiles for each aircraft, accounting for variables like aircraft age, flight routes, operational patterns, and environmental conditions. When sensor data deviates from expected patterns, the system calculates anomaly scores that indicate the severity and urgency of potential issues. Critical is the system’s ability to distinguish between benign variations (like expected performance differences between hot and cold weather operations) and genuine warning signs of impending failures.

Real-world examples demonstrate the life-saving potential of these systems: In 2023, Air France’s predictive maintenance system detected unusual vibration patterns in an A380’s number 2 engine during a routine transatlantic flight. The AI analysis, processing data from accelerometers and temperature sensors, identified a pattern consistent with developing turbine blade cracks—a condition that could lead to catastrophic engine failure if left unaddressed. The system recommended immediate inspection upon landing, and maintenance crews discovered three cracked blades that would have likely failed during the aircraft’s next flight.

British Airways’ predictive system flagged an anomalous pressure reading in a Boeing 777’s hydraulic system that traditional monitoring would have classified as within acceptable limits. Detailed AI analysis revealed the reading was part of a gradual degradation pattern, and inspection uncovered a developing seal failure that could have resulted in complete hydraulic system loss. Qantas implemented Airbus’s Skywise Health Monitoring, which predicted a potential landing gear actuator failure on an A330 three weeks before the component would have failed. The early warning allowed scheduled replacement during routine maintenance, avoiding what would have been an emergency gear extension situation.

The implementation architecture for these safety-critical systems includes multiple redundancy layers and validation steps: primary AI algorithms generate initial predictions, secondary validation systems verify these predictions using alternative analytical methods, human expert review confirms high-priority alerts before maintenance actions, and continuous feedback loops refine the algorithms based on actual inspection findings. This multi-layered approach ensures that false positives are minimized while genuine safety threats are never missed.

The Growing Market for Aviation Technology Solutions

The aviation industry’s embrace of AI prediction and big data has created a rapidly expanding market for aviation technology solutions, reflecting both the proven value of these systems and the increasing demand for enhanced aviation safety. According to Markets and Markets research, the global aviation predictive maintenance market is projected to grow from $4.5 billion in 2023 to $11.8 billion by 2030, with AI and machine learning technologies being the primary drivers. This explosive growth trajectory indicates that predictive maintenance has moved from experimental technology to essential infrastructure for modern airlines.

Several converging factors are fueling this market expansion. The regulatory environment increasingly favors data-driven maintenance approaches, with aviation authorities like the FAA and EASA developing frameworks that allow airlines to substitute traditional inspection schedules with condition-based maintenance when supported by robust predictive systems. Aircraft manufacturers are building more sophisticated sensor networks into new aircraft, with next-generation models like the Boeing 777X and Airbus A350 designed from the ground up to support predictive maintenance.

The proliferation of cloud computing and edge computing technologies has made it economically feasible to process and store the massive data volumes required for effective AI prediction. Additionally, the COVID-19 pandemic’s impact on airline finances has intensified focus on operational efficiency, making the cost savings from predictive maintenance particularly attractive.

The competitive landscape includes diverse players across the aviation technology ecosystem: Traditional aerospace companies like Boeing, Airbus, and Honeywell have developed proprietary predictive maintenance platforms (Boeing’s Airplane Health Management, Airbus’s Skywise, Honeywell Forge). Pure-play software companies like Palantir and C3 AI offer industry-agnostic machine learning platforms customized for aviation applications. Specialized aviation technology firms like Lufthansa Technik’s AVIATAR and Air France Industries KLM Engineering & Maintenance provide predictive maintenance as a service to other airlines. Cloud infrastructure providers including Microsoft Azure, Amazon Web Services, and Google Cloud Platform compete to host aviation data and analytics workloads, offering aviation-specific AI tools and compliance frameworks.

The investment and adoption patterns reveal strong industry confidence in these technologies. Delta Air Lines invested over $200 million in predictive maintenance infrastructure between 2020-2024, implementing systems across their entire fleet of 900+ aircraft. Emirates partnered with GE Aviation to deploy predictive analytics across their Boeing 777 fleet, processing over 500 terabytes of flight data annually. Smaller regional carriers are increasingly adopting maintenance-as-a-service offerings, where third-party providers handle the data infrastructure and AI analytics, making predictive maintenance accessible without massive capital investments. The market is also seeing consolidation, with major mergers like Collins Aerospace’s acquisition of predictive maintenance specialist Rockwell Collins, and strategic partnerships between airlines and technology companies to co-develop next-generation solutions.

Essential Data Infrastructure for Aircraft Health Monitoring

Building an effective predictive maintenance system begins with establishing robust data infrastructure capable of collecting, transmitting, storing, and processing the enormous volumes of information generated by modern aircraft. The foundational architecture requires integration across multiple technological layers, each serving specific functions in the data-driven maintenance ecosystem. Airlines must first ensure their aircraft are equipped with comprehensive sensor networks that capture relevant performance parameters—while newer aircraft like the Boeing 787 and Airbus A350 come with extensive built-in sensors, older fleet aircraft often require retrofitting with additional monitoring equipment to achieve sufficient data coverage.

The data collection layer involves thousands of sensors monitoring critical systems: engine health monitoring systems track over 200 parameters per engine including temperature at multiple stages, vibration patterns, oil pressure and quality, and fuel consumption rates. Structural health monitoring uses strain gauges and accelerometers to detect unusual stress or vibration in airframe components. Avionics health systems monitor the performance of navigation, communication, and control systems. Environmental sensors track cabin pressure, temperature, humidity, and air quality. Each sensor generates readings at frequencies ranging from once per second for critical parameters to once per minute for less critical measurements, creating data streams that must be captured without loss.

The implementation pathway follows these critical steps: Step 1 involves conducting a comprehensive fleet assessment to identify existing sensor coverage and gaps, typically requiring 2-3 months and costing $50,000-$150,000 per aircraft type depending on fleet size. Step 2 establishes data transmission infrastructure, either through ACARS (Aircraft Communications Addressing and Reporting System) for real-time transmission of critical parameters, or through post-flight data downloads via wireless or wired connections when aircraft are at the gate.

Airlines like United have implemented high-speed wireless download systems that transfer flight data in under 5 minutes during turnaround, enabling near-real-time analysis. Step 3 builds the data lake infrastructure, typically hosted on cloud platforms like AWS or Azure, with storage capacity planning based on data retention requirements—a typical wide-body aircraft generates 1-2 terabytes of data monthly, so a 200-aircraft fleet requires petabyte-scale storage with appropriate backup and archival systems.

Step 4 implements data cleaning and normalization pipelines that transform raw sensor readings into standardized formats suitable for analysis, filtering out transmission errors and sensor malfunctions. Step 5 establishes the analytics platform where machine learning models run, requiring significant computational resources—airlines typically provision hundreds of virtual machine instances for parallel processing of fleet-wide data.

Southwest Airlines’ implementation provides an instructive example: they began with a pilot program on 50 Boeing 737s, installing additional sensors and establishing data transmission protocols over 6 months. After validating data quality and transmission reliability, they expanded to their entire 750+ aircraft fleet over 18 months, investing approximately $85 million in infrastructure. Their data platform processes over 150 terabytes of flight data monthly, running predictive algorithms that generate maintenance recommendations reviewed by their engineering team daily.

Training AI Models for Accurate Defect Prediction

The effectiveness of predictive maintenance systems depends critically on the quality and accuracy of the machine learning models that analyze aircraft data and generate defect predictions. Training these models requires extensive historical data, domain expertise, and iterative refinement processes that can take months or years to achieve production-ready performance. The model training process begins with assembling comprehensive training datasets that include both normal operational data and examples of actual component failures, providing the AI algorithms with the patterns they need to learn to distinguish between healthy and failing systems.

Data preparation represents the most time-consuming phase of model development, often consuming 60-70% of the total project timeline. Engineers must collect years of historical sensor data, maintenance logs, and failure reports, then carefully label this data to indicate which readings correspond to normal operations versus pre-failure conditions. For example, if an engine bearing failed after 8,000 flight hours, engineers review sensor data from the preceding weeks and months, identifying the earliest point where anomalous patterns appeared.

This labeled data becomes the training examples that teach the algorithm what bearing failure “looks like” in the data. The challenge lies in the relative rarity of failures—modern aircraft are extremely reliable, so failure examples are sparse compared to normal operation data, creating class imbalance problems that require specialized machine learning techniques to address.

The model development workflow involves multiple specialized roles and tools: Data scientists select appropriate algorithms (neural networks for complex pattern recognition, decision trees for interpretable rules, support vector machines for classification tasks) and configure model architectures. Aviation maintenance engineers provide domain expertise, helping identify which sensor parameters are most relevant for predicting specific failure types and validating that model predictions align with mechanical understanding.

Software engineers build the production infrastructure that deploys trained models and integrates them with maintenance systems. The development typically follows an iterative cycle: train initial model on historical data, validate performance on held-out test data, deploy to shadow mode (generating predictions that are logged but not acted upon), compare predictions against actual maintenance findings, refine model based on discrepancies, and repeat until performance meets safety and reliability thresholds.

Lufthansa Technik’s AVIATAR platform development illustrates this process: their team spent 14 months assembling training data from over 6,000 aircraft across multiple airlines, covering 15 years of operational history. They developed separate specialized models for different component types—one model predicts engine issues, another focuses on landing gear, a third monitors avionics. Each model underwent rigorous validation requiring 90%+ accuracy in detecting actual failures while maintaining false positive rates below 5%. The models entered production only after demonstrating consistent performance across diverse aircraft types, operating conditions, and failure scenarios. Continuous monitoring tracks model performance in production, automatically flagging when prediction accuracy degrades below thresholds, triggering model retraining with updated data.

Integrating Predictive Systems with Maintenance Operations

The final critical element in successful predictive maintenance implementation is seamlessly integrating AI prediction systems with existing maintenance operations and workflows. Even the most accurate predictive models provide no value if maintenance teams cannot effectively act on their recommendations—integration requires careful change management, process redesign, and cultural shifts within maintenance organizations that have operated on traditional scheduled maintenance paradigms for decades.

The integration challenge encompasses multiple dimensions: technical integration connecting predictive systems with existing maintenance management software, work order systems, and parts inventory platforms; process integration redesigning maintenance planning workflows to incorporate AI-generated recommendations alongside traditional inspection schedules; organizational integration establishing clear roles and responsibilities for reviewing, validating, and acting on predictive alerts; and cultural integration building trust in AI systems among maintenance personnel who may be skeptical of computer-generated recommendations.

Successful integration follows a phased approach that builds confidence gradually: Phase 1 implements predictive systems in shadow mode, where AI generates recommendations that maintenance planners review but are not required to act upon, allowing teams to observe prediction accuracy without operational risk (typical duration: 3-6 months). Phase 2 introduces predictive recommendations as advisory inputs to maintenance planning, with experienced engineers reviewing each recommendation and deciding whether to act, creating feedback loops that help refine both the AI models and human understanding of their strengths and limitations (duration: 6-12 months).

Phase 3 elevates predictive recommendations to equal status with traditional maintenance triggers, where AI-flagged issues receive the same priority and response as scheduled inspections or pilot-reported problems (duration: ongoing). Phase 4 enables full predictive maintenance, where AI recommendations can automatically generate work orders for routine issues while human review focuses on complex or high-risk situations (achieved after 2-3 years of successful operation).

Delta Air Lines’ integration experience demonstrates the organizational change required: they established a dedicated Predictive Maintenance Operations Center staffed by engineers who review AI-generated alerts daily, triaging recommendations into immediate action, scheduled inspection, or continued monitoring categories. They developed standard operating procedures specifying how maintenance crews should respond to different alert types and severity levels. They implemented training programs ensuring all maintenance personnel understand how predictive systems work, what their limitations are, and how to provide feedback that improves model accuracy. They created performance dashboards tracking key metrics like prediction accuracy, false positive rates, maintenance cost savings, and safety incidents prevented, making the value of predictive maintenance visible across the organization.

The integration also requires addressing practical operational constraints: parts availability (ensuring predicted component replacements can be stocked in advance), maintenance slot scheduling (coordinating predicted maintenance with aircraft utilization plans and hangar availability), regulatory compliance (documenting that predictive maintenance meets airworthiness requirements), and workforce planning (ensuring sufficient skilled technicians are available when predictive systems identify multiple simultaneous issues).

Emerging Technologies Enhancing Predictive Capabilities

The current generation of AI prediction and big data systems represents just the beginning of aviation technology’s transformation—emerging technologies promise to further enhance predictive capabilities and aviation safety in ways that seemed impossible just a few years ago. Several cutting-edge developments are moving from research laboratories into operational testing, each offering potential breakthroughs in how airlines detect and prevent aircraft defects.

Digital twin technology creates virtual replicas of physical aircraft that simulate real-world performance in software, enabling engineers to test “what-if” scenarios and predict how specific components will age under different operational stresses. General Electric’s digital twin system for jet engines models over 1,000 components and their interactions, running physics-based simulations that predict component wear patterns with remarkable accuracy. When combined with real-time sensor data from actual engines, these digital twins can identify subtle deviations from expected behavior that indicate developing problems. Airbus is developing aircraft-level digital twins that model entire airframes, enabling structural health predictions that account for the complex interactions between different systems.

Edge computing and 5G connectivity are enabling real-time onboard data analysis rather than waiting for post-flight processing. Modern aircraft will increasingly perform AI prediction during flight, with onboard computers running machine learning models that can detect anomalies immediately and alert pilots or ground crews to emerging issues. This real-time capability is particularly valuable for long-haul international flights where immediate awareness of developing problems enables proactive decision-making about diversion airports or maintenance preparation at the destination.

Blockchain technology is being explored for creating immutable maintenance records and component histories, ensuring data integrity and enabling better tracking of parts throughout their lifecycle. When combined with predictive maintenance systems, blockchain-based component tracking ensures that AI models have accurate, tamper-proof information about each part’s history, improving prediction accuracy.

Advanced materials with embedded sensors represent another frontier—composite materials used in modern aircraft structures could be manufactured with built-in strain gauges and crack detection systems, providing continuous structural health monitoring at a granularity impossible with external sensors. Boeing is researching self-sensing composite materials for the 777X that would detect internal damage or stress concentrations automatically.

Regulatory Evolution and Industry Standardization

As predictive maintenance technologies mature and demonstrate proven safety benefits, regulatory frameworks are evolving to formally recognize and encourage these data-driven approaches while ensuring they meet rigorous safety standards. The Federal Aviation Administration (FAA) and European Union Aviation Safety Agency (EASA) are actively developing regulations and guidance materials that define acceptable practices for AI-based maintenance systems, creating the regulatory certainty airlines need to invest confidently in these technologies.

The FAA’s Condition-Based Maintenance (CBM) program allows airlines to substitute traditional time-based maintenance intervals with condition-based approaches when supported by robust data analysis systems. To qualify, airlines must demonstrate that their predictive systems meet specific reliability thresholds, maintain comprehensive audit trails, and include human oversight of critical decisions. Several major airlines have already received FAA approval for CBM programs on specific aircraft systems, paving the way for broader adoption. EASA has published similar guidance through its Performance-Based Maintenance framework, emphasizing that predictive systems must demonstrate equal or superior safety outcomes compared to traditional maintenance approaches.

Industry standardization efforts are addressing the technical fragmentation that currently limits data sharing and system interoperability. The Aerospace Industries Association (AIA) is developing standard data formats for aircraft health information, enabling airlines to more easily integrate systems from multiple vendors. The International Air Transport Association (IATA) is leading initiatives to establish common predictive maintenance key performance indicators (KPIs) that enable airlines to benchmark their system effectiveness and share best practices. These standardization efforts will accelerate aviation technology adoption by reducing implementation costs and technical risks.

Expanding Beyond Commercial Aviation

While commercial airlines have led the adoption of AI prediction and predictive maintenance, these technologies are expanding into other aviation sectors where they offer similar safety and efficiency benefits. Military aviation is implementing predictive maintenance to improve readiness rates and reduce operating costs for fighter jets, transport aircraft, and helicopters. The U.S. Air Force’s Predictive Maintenance program uses machine learning to forecast component failures on F-35 fighters, significantly improving mission availability.

Business aviation operators are adopting scaled-down predictive systems appropriate for smaller fleets, with companies like Honeywell offering subscription-based predictive maintenance services for corporate jets. General aviation, while slower to adopt due to cost constraints, is beginning to see entry-level predictive systems that monitor critical engine parameters on piston aircraft, providing early warning of potentially catastrophic engine failures.

The helicopter industry faces unique maintenance challenges due to the mechanical complexity and vibration stresses inherent in rotorcraft operations—predictive maintenance systems specifically designed for helicopters are showing particular promise in reducing unscheduled maintenance and improving safety. Unmanned aerial vehicles (drones) represent an emerging application area where predictive maintenance enables autonomous systems to self-monitor and schedule their own maintenance, essential for large-scale commercial drone operations.

This cross-sector expansion creates network effects that benefit all aviation segments: as more aircraft types and operators adopt predictive maintenance, the collective data pool grows larger, enabling more accurate predictions and faster identification of rare failure modes. The aviation technology ecosystem is becoming increasingly interconnected, with data sharing agreements and collaborative research initiatives that advance the entire industry’s safety and efficiency.
