A flight operational method for evaluating the effectiveness of visual approach and landing aids is described. The method is based on a quantitative appraisal of the guidance obtained from a given configuration of lights by measuring the quality of the approach and landing and by determining the pilots effort in carrying out these manoeuvres. To this end, relevant flight technical and physiological measurements are made and the test results are expressed in quality marks by means of a specially developed interpretation procedure. For simulating consistent and marginal weather conditions a cockpit fog simulator has been developed consisting of a gyro- and altitude-controlled movable opaque screen mounted in front of the subject pilot. The safety pilot is not subjected to any restriction of visibility. The tests are performed on a statistical basis so that the real significance of the differences in effectiveness between light configurations as found from the trials can be determined.
