CORRESPONDENCE ANALYSIS IN EXAMINATION OF REASONS FOR FLIGHT SCHEDULE PERTURBATIONS

This paper presents the results of analysis of reasons for flight schedule perturbations and the possibilities of their elimination. Correspondence analysis was used for statistical analysis on the JAT Airways database for reasons for departure delays and their length. There was indication of positive correlation between the reasons and the delays. But for more detailed insight into the relationship between departure delay length and their reasons, as well as the likelihood of their elimination, more homogenous data analysis was necessary (e.g. domestic flights, flights from Belgrade etc). After the proposed database analysis was completed it was concluded that there are some reasons for short departure delays (up to 45 minutes) which are the consequence of the JAT airline omissions. The number of these flight delays is considerable and they can produce serious flight schedule perturbations which could be eliminated with relatively ease by correcting these airline omissions
