Abstract:
A method for presenting the current drift values of an aircraft on a display device in which the drift values are presented in a vector presentation. The length of the drift vector above a predefined threshold value is presented in a manner proportional to the current drift velocity, and the length of the drift vector below the threshold value is presented in a manner disproportionate to the current drift velocity. There is a continuous transition between the two ways of presentation at the threshold value.
Abstract:
A method for producing a sensor-supported, synthetic view for landing support of helicopters under brown-out or white-out conditions is provided. A virtual 3-D representation of the landing zone is continuously created from 3-D data of the intended landing zone recorded during the landing approach and a monitoring routine is available to ensure that no 3-D data that was produced under brown-out or white-out conditions is considered in the representation. As soon as the monitoring routine detects that 3-D data has been recorded under brown-out or white-out conditions, an additional radar sensor is activated to continuously produce distance and/or Doppler data of potential objects entering the landing zone, the objects being displayed to a pilot of the landing helicopter in the synthetic view.
Abstract:
A method for assessing a ground area for suitability as a landing zone or taxi area for aircraft is provided. Three-dimensional data for the ground area in a plurality of measurement cycles in a 3D sensor is produced. The measured-value density of the three-dimensional data and also of at least one further statistical property of the three-dimensional data is determined. A measure of the local roughness of the ground area is produced based on the measured-value density and the at least one further statistical property. The individual area elements of the ground area are classified on the basis of the roughness values produced according to the degree of suitability of said area elements as a landing area or taxi area.
Abstract:
Method for pilot assistance in landing an aircraft with restricted visibility, in which the position of a landing point is defined by at least one of a motion compensated, aircraft based helmet sight system and a remotely controlled camera during a landing approach, and with the landing point is displayed on a ground surface in the at least one of the helmet sight system and the remotely controlled camera by production of symbols that conform with the outside view. The method includes one of producing or calculating during an approach, a ground surface based on measurement data from an aircraft based 3D sensor, and providing both the 3D measurement data of the ground surface and a definition of the landing point with reference to a same aircraft fixed coordinate system.
Abstract:
A man-machine interface for assisting a pilot during takeoff or landing of an airborne vehicle in reduced external visibility includes a display which represents a virtual scenario from the perspective of a virtual observer who is himself located behind the airborne vehicle and is in the same flight attitude as the airborne vehicle itself. The virtual scenario includes a base plane which symbolizes an idealized ground surface, calculated from the instantaneous value of the altitude above ground and the instantaneous flight attitude data of the aircraft. The base plane is bounded by an artificial horizon and is continuously updated with the instantaneous flying state data and the instantaneous height above ground. The virtual scenario also includes a symbol which represents the airborne vehicle, and the position of the symbol relative to the base plane represents the current flight attitude and the instantaneous height of the airborne vehicle above ground.
