Visibility Concepts and Measurement Techniques for Aviation Purposes

reportActive / Technical Report | Accession Number: AD0744688 | Open PDF

Abstract:

The report reviews present techniques for measuring atmospheric transmittance and its conversion to runway visual range. The response of the pilot to visual cues used in determining the visibility is discussed as a function of his cockpit environment. The lights used by the FAA as targets for visibility determinations are discussed and used in the computations. New techniques for visibility measurements and new concepts and definitions are discussed and analyzed. The emphasis is on techniques for measuring slant visual range by means of optical remote sensing devices. Various problems relating to atmospheric modeling, signal processing, and eye safety aspects are discussed.
