Abstract
Visibility can decrease when weather such as rain, snow, fog, and mist are present. When visibility deteriorates, pilots and airtraffic controller’s encounter operational constraints, leading to aircraft diversions, ground stops, and departure delays. Prolonged low-visibility events increase safety risks for passengers, crew, and aircraft, potentially resulting in collisions. This case study examined the impact of low visibility at Philadelphia International Airport (KPHL) in December 2023, analyzing its effects on arriving and departing flights. Using archived METAR, FAA documentation, and satellite, it was assessed how visibility influences flight diversions and delays. This study presents a time-series analysis of low-visibility events, associated weather conditions, and the total number of affected operations throughout the month. The findings highlight the critical role of weather in air traffic disruptions and emphasize the need for improved operational strategies to mitigate delays and ensure safety.
