This study examined trends over time based on flight lesson cancellation types at Part 141 flight school in Florida from 2010 to 2019. Identifying such trends is crucial for developing strategies for reducing future flight cancellations. Flight lesson cancellations were pre-categorized into four types: weather-related, student-related, instructor-related, and maintenance-related. The hypothesis was that there would be a significant trend over time for each flight cancellation type from 2010 to 2019 in part 141 of the collegiate flight program in Florida. Using a predictive correlational design, this study analyzed the archival cancellation data. Between 2010 and 2019, the total number of flight lesson cancellations was 27,320, based on archival data from 544 students. Based on the descriptive statistics, weather-related cancellations had the largest mean (22.43) and standard deviation (18.21), suggesting greater unpredictability. Linear regressions for each type of flight cancellation showed statistically significant trends that decreased from 2010 to 2019. These findings contribute to our understanding of cancellation trends, emphasizing the ongoing reduction in cancellations during the study period.
