A method for correcting the of a board - altimeter of an aircraft height supplied via normal - zero

摘要

A method for the correction of the supplied by an altimeter value of the absolute height above nz (za) of an aircraft with the aid of a three-dimensional digitized representation of the relief on board the aircraft, having means to its height (ha) with respect to a sensor, and relief, whereby– a horizontal flight path (22) of the aircraft is determined on which the measurements of the height (za) of the aircraft above nz and its height (ha) via the relief on the digitized representation and the read height (zs) of the relief is compared, by a correction value (dz) for correcting the height (za) to determine the altimeter,– on the digitized representation of a horizontal grid (10) is formed and each grating field (21) an average datum level (zos) of the relief is associated with,– the flight path (22) in sections (23 - 29) (12) is divided in the scanned grating fields (21) are,characterized in that– each grating field (21) also a reference - standard deviation (it) is associated with..
