This plan is part of documentation supporting one aspect of the program,visual ground aids development. There are twenty-four concerns with the present visual ground aids. The concerns deal with the ability of the present system and its components to support taxiing operations in the lower visibility environment found during Category III conditions. This report describes an engineering and development plan which will identify solutions for the concerns,create the specifications for improved visual ground aids and lay the ground work for application in future Category III operations. The management of the development process leading to major improvements in the present system is described. The plan includes a schedule,budget,milestones and evaluation criteria. (Author) 收起
