Constructing and Displaying the Trajectory Path on the Aircraft On-board Cockpit Multifunction Displays

Abstract

Background/Objectives: development of algorithms for flight plan data transformation into the projected trajectory of the aircraft based on the unification of used trajectories in the horizontal plane to reduce the consumed computing resources. Methods: In order to display the flight route, specialized software is used in the on-board systems enabling to convert a flight plan data set into a predictable trajectory of the aircraft path for its subsequent visualization. Findings: The authors have defined, developed and presented the principles and algorithms for computation of route trajectories ensuring the building of calculated flight path of the aircraft to be displayed on the on-board displays. The route displaying is carried out by consistent plotting of the typical trajectories that constitute the route path and in their turn consist of a set of graphic primitives such as line and arc. The database to be displayed is based on the flight plan, made in accordance with the Jeppesen database or similar, after bringing it to the formats of three typical defined trajectories. Applications/Improvements: The algorithms of the flight plan data conversion into a projected trajectory in the horizontal plane unify the process of information generation for displaying on the on-board multifunction displays and optimize a set of computation data to control the motion along a trajectory.
