Abstract

An air traffic control support system comprises:

a wake turbulence detecting unit adapted to detect a wake turbulence occurring in a runway sky due to taking off or landing of an aircraft;

a decay time predicting unit adapted to predict decay time of the wake turbulence;

a weather information acquiring unit adapted to acquire weather information in the surroundings around the runway; and

a display unit adapted to display the decay time,

wherein the decay time predicting unit predicts the decay time of the wake turbulence detected by the wake turbulence detecting unit on the basis of the weather information.
