TRANSMISSOMETER CALIBRATION TECHNIQUES.
Abstract
The report is devoted to the investigation, analysis, and specification of transmissometer procedures and techniques which may be accomplished without the need of specialized calibration devices. Two side-by-side, 250-ft. baseline transmissometers are used to isolate calibration techniques that may be useful under all visibility conditions. Past calibration procedures were limited to application in visibility of 5 miles or more. The report shows that these calibration procedures can be successfully applied when the visibility is as low as 2 miles. Preventive maintenance procedures which may be used to minimize transmissometer outages are discussed. Other results show that it is not possible to calibrate a transmissometer by using data from a nearby system(s) on an airfield. (Author)
