5.1 Language. Common nouns and verbs, as well as special terminology, shall be used

consistently. For example, the user shall not be told to "press" a switch in one message and "depress" it in another.

5.1.1 Equipment identification. Items of equipment shall be identified only by nomenclature used in the repair parts and special tools list (RPSTL) or in other terms specifically approved by the Government.

5.1.2 Abbreviations and acronyms. Information shall be displayed in plain concise text wherever possible. Abbreviations and acronyms not peculiar to a specific system shall be from appendix A of this document or from ASME Y14.38.

5.1.3 Display codes. Approved abbreviations, acronyms, or display codes shall be used where space does not permit plain text.

5.1.4 Feedback. Feedback shall be provided to the operator to indicate the status of test program processing and provide for user confidence. Feedback shall conform to the following:

a. Periodic feedback shall be provided to the operator to indicate normal system operation when test program processing requires the operator to stand by for more than 15 seconds without making a response.

b. The operator shall be informed at least once before the test or tests are initiated when a testing event or a series of testing events technically prohibits interruption to inform the operator.

c. Positive indication shall be presented to the operator about the outcome of the process and the requirements for subsequent operator actions when a process or sequence is completed or aborted by the system or TPS.

d. Feedback shall be provided to indicate the reason for rejection and the required corrective action if the system rejects an operator input. Feedback shall be self-explanatory or coded in a manner clearly understood by the target audience.

5.2 Format design.

5.2.1 Display formats. Display formats shall be designed to optimize information coding, grouping, and appropriate information density. Where applicable, the criteria of MIL-STD-1472 shall apply.

5.2.2 Grouping. Displayed data necessary to support an operator activity or sequence of activities shall be grouped together.

5.2.3 Tabular data display. Tabular data shall be captioned.

5.2.3.1 Tabular data. Tabular data shall be presented in a row- column display.

5.2.3.2 Recurring data. Location of recurring data shall be similar among all tabular data displayed.
