At busy airports aircraft departures are often delayed for a long time because of runway congestion. There is a known algorithm for optimizing the flow of outbound aircraft by the criterion of minimal runway-occupancy time which allows the average aircraft delay to be reduced and the runway capacity to be increased. In the paper the influence of the optimization algorithm on fuel consumption is analyzed and the economic benefit of its use is estimated. The modelling results showed optimization usefulness provided that the traffic is of high intensity.

Key words: air traffic control, capacity, runway, queue, Poisson flow, optimization.

The article describes the study of the accuracy of determination of coordinates of air targets in multipositional surveillance system using the signals of navigation satellites of global navigation satellite systems and pseudolite signals to illuminate air targets. It is shown that the use of pseudolite signals allows to reduce the peak error 8-10 times and decrease the average error of measurement of coordinates of air targets 2-3 times in a multipositional satellite surveillance system.

Key words: global navigation satellite system, multipositional surveillance system, the error of measurement of coordinates, operating zone.

The article analyzes the influence of environmental helio-geophysical factors perturbation on physical and chemical properties of water, such as specific conductivity, oxidation-reduction potential, a hydrogen index that are authentically registered in water electrochemical cells by environmetrical methods. Examples of aviation incidents are given and their reasons according to official investigation materials are explained. The authors draw a conclusion that the helio-geophysical factors can influence a person behavior and its possible deviations generally called Β«a human factorΒ» – one of the reasons of various aircraft accidents.

Keywords: flight safety; aviation incident; human factor; cosmophysical and geophysical factors; danger.
