This is achieved by controlling the aircraft’s airspeed, altitude, heading and vertical speed in order to arrive to the merging point in a specified time. The system receives data from the aircraft and computes new control parameters based on mathematical equations and algorithms of prediction trajectories. Additional features have been added to the FMS-4D, such as the capability of predicting the arrival time taking into account previous flight parameters and speed/altitude constrains. Finally, a testing phase was carried out using a flight simulator in order to obtain the performance and results of the designed system.

An overhead line electric and magnetic field strength measurement method is presented according to which the field data of overhead lines has been measured. The measurement values of the electric and magnetic field of overhead lines were compared with theoretical calculations. Unmanned aircraft control has been investigated by assessing the impact of the electromagnetic field, in order to determine the strength of the electromotive force which is induced within aircraft circuits when an unmanned aircraft reaches the live parts of overhead lines.

There is described the problem of the pilots’ workload in the cockpit and its issue on the flight safety. The goal of this research is to find out the gaze movement pattern of student-pilots and compare it to the theoretical models. The gaze direction is closely related to the attention concentration point. So by means of gaze tracking it is possible to determine where the pilot concentrates his attention. It is accomplished by implementation of mobile eye-tracking system which consists of one eye camera and one scene camera. The experimentation was accomplished and data collected in the flight simulator. At the end of the thesis research conclusions are represented.

The research is done with mathematical UAV model, which eliminates aerodynamics while the chosen flight path is followed by using vector field method. Lots of attention is dedicated to show possible flight path error values with representation of modelled flight path trajectories and deviations from the flight mission path. All of the modelled flight missions are done in two-dimensional space and all of the collected data with flight path error values are evaluated statistically. The most possible theoretical flight path error values are found and the general flight path error tendencies are predicted.

In order to meet the needs of all airspace users, aircraft flows are being increased, and different aircraft systems that minimise the risk of aircraft accidents are being developed to ensure flight safety. However, statistically, the impact of the human factor on aviation accidents and incidents remains high. This article focuses оn thе аssеssmеnt оf pіlоt flіght ассurасу during route flights and presents a mеthоdоlоgу bаsеd оn automated assessment tunnels for accurately assessing pilot flight dеviаtiоns frоm a prе-sеt flіght trаjесtоrу axis both on the horizontal and vertical plane.

In paper, we present general equations, which can be used for generating waypoint-switching methods when for experiment purpose mathematical UAV model is used. UAV is modelled as moving dot, which eliminates all of the aerodynamics factors and we can concentrate only on the navigation problems. Lots of attention is dedicated to show possible flight path error values with representation of modelled flight path trajectories and deviations from the flight mission path. All of the modelled flight missions are done in two-dimensional space and all the results are evaluated by looking at Probability Density Function (PDF) values, as we are mostly interested in the probability of the error.

This interest is mainly driven by the necessity to meet the rules and restrictions for small UAV flights that are issued by various international and national legal organizations. In order to lower these restrictions, new levels of automation and flight safety must be reached. In this paper, a new method for ground obstacle avoidance derived by using UAV navigation based on the Dubins paths algorithm is presented. The accuracy of the proposed method has been tested, and research results have been obtained by using Software-in-the-Loop (SITL) simulation and real UAV flights, with the measurements done with a low cost Global Navigation Satellite System (GNSS) sensor. All tests were carried out in a three-dimensional space, but the height accuracy was not assessed. The GNSS navigation data for the ground obstacle avoidance algorithm is evaluated statistically.
