Paired departure is an effective way to reduce longitudinal distance between aircrafts on closely spaced parallel runways by avoiding wake turbulence, to increase airport capacity. However, details of operation have not come to agreement. According to this, by modeling security body of aircraft in the air, the model of protection zone in paired departure can be constructed. The maximum of safe distance in paired departure and departure time lag can be got, by which it provides computation basis of maximal longitudinal separation between aircrafts and the departure time of trailing aircraft. Further more, this research reveals the relationship of the leading and trailing aircrafts´ velocity in paired departure. At last, the research gets relationship of variables to prove model.
