The visiblity of targets on the ground for observers in an aircraft was studied by means of naked eye observations from a helicopter. The maximum flight altitudes at which detection, recognition, or identification of ground targets is still possible were calculated under the assumption that the visibility distance is a lagarithmic function of the altitude. The constants of this function were determined experimentally, and are given.
