A Configuration Design Concept for Distance Coded Marking of Category II and IIIA Runways

Eight experiments were conducted in a program with the objective of providing a configurational design concept for a system of distance coded runway marking geared particularly to the support of landing and take-off operations in Category II and III-A bright daylight contact fogs (fog extending to the surface -no ceiling). Among other criteria the system must meet are distance coding of a bidirectional runway, compatibility with runway lighting, and resistance to loss of configurational integrity through operational wear. A symbolic distance indicating system was regarded as having demonstrated the greatest potential for meeting the full array of design objectives and is recommended for service test and evaluation.
