| Abstract | The forward scattermeter has many practical advantages over the transmissometer (single mounting pole, greater dynamic range, etc.). However, before a forward scattermeter could be accepted for an RVR system, a number of criteria had to be satisfied: 1) the calibration must be accurate and consistent (a) from one unit to the next and (b) for all important obstruction to vision (fog and snow for RVR); 2) the windows of the sensors must not clog in blowing snow; and 3) scatter measurements in a small volume of space must represent conditions over the runway as well as measurements made by a transmissometer which averages over a baseline (250 feet (76.2 m) at US airports). Many different scattermeter designs were tested extensively, both in the field and in climatic chambers, before all acceptance criteria could be satisfied. The report describes the evolution of scattermeter design and presents the test methodology and results for the new RVR system. |
