Abstract: A method and a system are provided herein for calculating whether or not a specific aerial vehicle at a specified point of time can maneuver over a given location in the terrain while complying with terrain clearance requirements. The system may include a computer memory configured to store a 3D model representing at least a portion of a terrain located in a vicinity of an aerial vehicle; a computer processor configured to map said portion of the terrain into at least two types: a first type indicative of a potential of the aerial vehicle to maneuver over a respective terrain while complying with terrain clearance, and a second type indicative of a non-potential of said aerial vehicle to maneuver over a respective terrain, wherein the mapping is carried out based on said parameters, the 3D model and given predefined performance of the aerial vehicle.

Abstract: A method and a system for displaying a scene to a user wearing ahead mounted display (HMD) while removing obstructions in a field of view (FOV) of the user are provided herein. The method may include: capturing by a sensor a vehicle image of the scene wherein the first sensor is mounted on the vehicle; tracking a position and orientation of the HMD in a specified coordinate system, to yield a line of sight (LOS) of the user wearing the HMD; obtaining a database containing obstacles data indicating at least one physical object located within the vehicle and affecting the FOV of the user; calculating an obstructed portion in the FOV of the user, based on the LOS and the database; generating from the vehicle image, an un-obstructed view which includes a portion of the scene overlapping the obstructed portion; and displaying in the HMD the un-obstructed view.

Abstract: Head mounted displays (HMD) and corresponding display methods are provided, which obtain, repeatedly, from a monitoring system of a vehicle and, a reference vector relating to the vehicle; display on the HMD a reference symbol that indicates the reference vector; and determine movements of a HMD symbology according to a spatial relation between a received user's line of sight (LOS) and the reference vector. For example, the vehicle may be an aircraft and the reference vector a flight path vector (FPV) received from the aircraft's avionics. The proposed HMD enhances the displayed information content while avoiding excessive movements of the symbology. The HMD's functional parameters may be pre-set or adapted according to user preference and flight stage characteristics. The reference symbol anchors most of the symbology, while minimal critical information may be moved along with the user's LOS, providing a clearer and more stable view through the HMD.
