Abstract
A method for supporting low-level aircraft flights in which a warning is provided for the pilot upon a reliable recognition of wire-like obstacles, even during extreme environmental influences, such as clutter, or even when such obstacles are seen against the sky. The method is performed upon the collection of information on the topography of the surrounding terrain by at least one sensor located on the aircraft, such information representing raw data, based upon which an image-like representation is calculated, such representation including a pixel quantity with pixels P(i, j) in columns j and lines i, which image-like representation is evaluated by calculating altitude values in a geodetic coordinate system using the flight condition from the aircraft, evaluating pixel quantity by comparing each pixel P(l, j) to threshold values or ranges of values, evaluating the image-like representation and highlighting each pixel as a picture element if any of various cases is present.
