The model, the task analysis results, and a survey of equipment for reference displays were all used to evaluate design alternatives for indexing, storage forms, storage media, and displays, as well as requirements and displays for auxiliary data. Three modes of TIIF operation-manual, semi-automated, and automated-were considered. Reference storage forms, media, and displays should be selected in the context of a manual or automated TIIF system. For a manual system, references should be in their original form and stored in file cabinets. For an automated system, references should be standardized according to interpreter needs and controlled by a computer processing unit. Reference indexes should be designed for each type of reference, utilizing existing indexes as far as possible. Collection and processing of auxiliary information should be automated for ease of subsequent processing. The code matrix block should be used whenever possible. The displays of auxiliary information should relate to whether the system is manual or automated. For the manual system, auxiliary displays should be viewed in hard copy or in the original format. For the automated system, displays, if needed, should be under computer control. Additional information for a code matrix block should include aircraft stabilization data. (Author).
