  7. Abstract:
  8. In today's complex engineering systems, any increase in efficiency naturally comes with concerns about accepted level of safety. As demand for aerial transportation is increasing, more researches are conducted to increase the capacity of current controlled airspaces; as the limited capacity of the so called "en-route" corridors appears to be the main concern in the industry. Meanwhile, a solution is expected to be in more efficient exploitation of the current airspace capacities via optimizing the standards related to maintaining Separation Minima (SM) among flying aircrafts. Current standards assume an aircraft to be at the center of a circle with a radius equal to 5 nm. In this work, however, we show other optimal figures beside a circle exist which could help increase the airspace capacities. Through proper modeling of different factors involved in computation of the minimum SM, and with the help Genetic Algorithm, as an optimization technique, we investigate new figures with the same level of safety. The relevant factors include aircraft navigation errors. Different case studies show an oval shape could easily increase the existing airspace capacity as much as %20, while maintaining the same level of safety
