What is it about?
This study explores how machine learning can help airlines identify wear patterns for aircraft braking systems. By analyzing data from flights, including aircraft parameters, weather conditions, and airport characteristics, the research clusters flights based on wear severity without relying on predefined labels, using different machine learning techniques. The findings can help airlines optimize maintenance schedules, reducing unexpected failures and saving costs while improving aircraft safety.

Why is it important?
Aircraft brakes undergo wear over time, and understanding the factors that influence this process is crucial for safety and maintenance planning. Traditional maintenance schedules rely on fixed timelines rather than real-time wear assessment, leading to unnecessary inspections or unexpected failures. This research leverages modern machine learning techniques to detect wear patterns and determine key factors influencing brake degradation based on specific airline operations. By improving brake wear predictions, airlines can schedule maintenance more efficiently, extend brake life, and reduce downtime—enhancing both safety and operational efficiency.
Perspectives
This research represents an important step toward predictive maintenance by integrating data-driven insights into traditional engineering processes. Unlike previous studies that primarily used supervised learning or physics-based models, this work emphasizes unsupervised learning to detect hidden patterns in wear data. The results have the potential to transform how airlines approach maintenance, shifting from fixed schedules to more dynamic, condition-based strategies. Moving forward, integrating this approach with predictive maintenance frameworks across other wear-prone aircraft systems could further enhance operational efficiency and cost savings.
