The invention belongs to the technical field of avionics, and particularly discloses an airborne synthetic visual dynamic threat intelligent identification system based on multi-source fusion, which comprises a multi-source data acquisition module, an integrated GNSS unit, an IMU unit, a camera, a laser radar and a millimeter wave radar, and is used for acquiring images, point cloud and meteorological data of a flight environment through a space-time calibration mechanism; the dynamic threat analysis module is used for performing fusion processing on the multi-source data, identifying a dynamic threat target based on a target detection model and outputting a threat level; and the visual scene display module is used for dynamically adjusting the display content and the alarm mode of the synthetic visual scene according to the threat level in combination with the eye movement tracking data and the flight stage information. The problems that a traditional synthetic visual system is lagged in dynamic threat perception, insufficient in multi-source data fusion and low in man-machine interaction efficiency are solved, and the situation awareness and safety guarantee capability of an aircraft in a complex airspace environment is remarkably improved.

Aircraft systems and methods are provided for displaying attributes on a forward-looking graphical user interface display. An exemplary method involves determining candidate display positions for an attribute associated with a displayed object based at least in part on the geographic location and the altitude associated with the object, selecting, from among the candidate display positions, a visible display position for the attribute based at least in part on relationship between the visible display position and a reference display position for the attribute, and rendering a graphical representation of the attribute at the visible display position on the forward-looking graphical user interface display.

An enhanced vision system (EVS) is integrated with a heads-up display (HUD). The EVS generates image of an external scene. The EVS generates the images without repeatedly generating the images when a mode of the HUD changes. The EVS includes an expanded interface, where inputs from the HUD are used in the internal processing of the EVS. The HUD then displays information in a graphical and alphanumeric format. The information can include an enhanced vision image from the EVS and / or a synthetic vision image from a synthetic vision system (SVS). The enhanced vision image can be merged with a synthetic vision image to provide a combined vision image.
