Patent number: 10281574Abstract: 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.

Patent number: 8803727Abstract: 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.Type: GrantFiled: June 29, 2010Date of Patent: August 12, 2014Assignee: EADS Deutschland GmbHInventors: Thomas Muensterer, Matthias Wegner, Peter Kielhorn

Patent number: 8305238Abstract: 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.Type: GrantFiled: September 22, 2009Date of Patent: November 6, 2012Assignee: EADS Deutschland GmbHInventors: Matthias Wegner, Thomas Muensterer, Patrick Kramper, Peter Kielhorn
