Abstract : Hourly surface weather observations are combined with air traffic records to calculate the percentage interruption in airport runway operations due to fog that can be expected at 25 Air Force bases in the United States (17) and Europe (8). It is projected that approximately 1 to 2 percent of the flights in an average year can be expected to be affected by fog at bases in the United States. In Europe, the figures rise to 2 to 4 percent. During heavily fog plagued years, the projections can be expected to double. Persistence times are approximated. Empirical equations to allow calculation of percent mission interruption and duration of the interruption are presented that allow estimates to be made for bases other than the 25 selected for this investigation.
