Abstract:

A system study was carried out to determine the requirements for effective marking of overhead obstructions of low visibility that are potential aviation hazards. The design of effective markers is based on a knowledge of vision through the atmosphere. A simple theory on the subject is presented. Design concepts based on the theory to meet the requirements determined from the system study are proposed. The concepts are evaluated and tested with models in laboratory and in actual field conditions. Engineering designs of these concepts are also furnished. Author
