Weather Hazards and their Implications on Flight Operations in Abuja Airport, Nigeria

Abstract

The results of the tested hypothesis on the effect of weather hazards on flight cancellations show R2 value of O.383.This indicates that 38 percent of the total variations in flight cancellations are explained by these variables. The F-value of 7.043 (greater than 3 . 84) shows that the four variables arc jointly significant in predicting flight cancellations in Abuja within the studied period. Results further reveal that both thunderstorms and rainfall are significant in explaining flight cancellations in Abuja (since the F-value both of them are greater than l .96). However. fogs and dust haze were found not to be significant. On the effects of thunderstorms. fog, dust haze and rainfall on flight delays. a R2 value of 0.526 obtain indicates that 53 percent of the total variations in flight delays are explained jointly by these variables. The F-value of l 8.804 (greater than 3.84) indicates that the four variables are jointly significant in predicting flight delay in Abuja Results also show that thunderstorms and fogs are significant in explaining flight delays in the study area. Dust haze and rainfall were found not to be significant since the absolute value of their calculated value is less than l.96.
