Abstract: An aircraft navigation system and a method for aircraft navigation is presented. The aircraft navigation system has a navigation-map data source, navigation-map data provided by the navigation-map data source including information about a multitude of objects O on earth surface which are of high potential visibility and high potential identifiability from elevated positions, each information for an object O?O including a position and a type of the respective object O; a first system for measuring an actual aircraft position P(t); a waypoint data source providing waypoints WPi defining an aircraft intended flight track; a second system for selecting per waypoint WPi one object Oi(WPi) with Oi(WPi)?O depending on given selection criteria; and a display for displaying an information I(Oi(WPi) referring the selected object Oi(WPi).

Abstract: A method and device to create a realistic and flexible test environment for the evaluation of augmented reality application and device. The test method and the test device for testing the function and/or use of a head worn see through augmented reality device by means of a virtual reality environment, comprises a head mounted device. The head mounted display includes a virtual reality head mounted display configured to display the virtual reality environment to the eyes of a user through the head worn see through augmented reality device, and an alignment device to align the head mounted display and the head worn see through augmented reality device.
