The paper deals with restrictions on airport capacity associated with the potential hazard for an aircraft in takeoff or landing to encounter the vortex wake generated by another aircraft. The complexity of the problem under study and the lack of a single research tool make one employ a “mosaic” approach based on combined use of various methods. A specific difficulty therewith appears of asymptotically non-rigorous division of the problem into subproblems and of thoroughly matching the results obtained. The goal of this work is to validate and assess the potentialities of the methods used and to reveal their weaknesses and strengths as well as to discuss the results obtained.
