PRINCIPLES OF INDICATION FOR EN-ROUTE FLIGHT PATHS OF THE AIRCRAFT ON THE SCREEN OF ON-BOARD DISPLAY DEVICES

Subject of Research.We consider the principles and algorithms for construction of en-route flight paths of an aircraft (airplane) in a horizontal plane for their subsequent display on the navigation situation indicators in the cockpit. Navigation situation indicatorsaredisplay devices designed on the basis of flat liquid crystal panel. Methods. Flight trajectory display by on-board multifunction indicators is performed by successive drawing of graphic primitives available in the library and defined in accordance with an array of data to display the route. An array of data is generated by on-board software complex based on the information provided in the flight task and the corresponding «Jeppesen» database or analogous one. Formation of the array is carried out by bringing the set of trajectory paths to the format of three typical trajectories described. In addition, each of the types of trajectories has a standard description of the algorithm for calculating the parameters that make up an array of data to display.Main Results.The algorithms of forming and calculating the amounts of data of routing paths required for their construction and display on the multifunction indicators applied in avionics.Practical Relevance.These novel routing algorithms for constructing trajectory paths unify algorithms of generating information for display on the navigation situation indicators and optimize a set of calculated data for flight control at the trajectory in the horizontal plane.
