Sažetak
With the growing air traffic intensity, at some airports we are more often faced with the fact that aircraft land or take off one after another. Since every aircraft leaves a turbulent vortex behind, which acts unexpectedly and is destabilising for the aircraft flying into it, the flight safety in such repeated landings and takeoffs becomes questionable. Determining the minimum safety time interval between the repeated operations becomes imperative and a limiting factor for some airports with high air traffic intensity. Unlike military flying, where crew is trained to fly in a group, in civil air traffic the crew is not trained for such flying and on top of it mostly operate on large aircraft, which produce very strong turbulent vortex. Additional sophisticated equipment in new modern aircraft improves navigation, communication and steering of the aircraft, but does not insure it from flying into an invisible turbulent vortex. This paper discusses the vortex generation, its nature and factors that influence its intensity and duration. The paper also deals with a model of calculating the probability of flying into a turbulent vortex regarding time interval of repeated operations, and influence of sophisticated equipment installed, on the stability and flight safety of an aircraft. Conclusion underlines the need to standardise the minimum safety time interval separation between the repeated operations, with the aim of improving flight safety.
