5. DETAILED REQUIREMENTS
5.1 Control-display intimation.
5.1.1 General criteria.
The relationships of a control to its associated display and the display to the control shall be immediately apparent and unambiguous to the operator. A control should be located adjacent to (normally under or to the right of) its associated display and positioned so that neither the control nor the hand normally used for setting the control will obscure the display.
Control-display relationships shall be apparent through proximity, similarity of groupings, coding, framing, labeling, and similar techniques.
22.214.171.124 Complexity and precision.
The complexity and precision required for control manipulation and display monitoring should be consistent with the precision required of the system. Control-display complexity and precision shall not exceed the operator’s capability to discriminate display detail or manipulate controls (in terms of manual dexterity, coordination or reaction time) under the dynamic conditions and environment in which human performance is expected to occur.

This standard establishes general human engineering design criteria for military systems, subsystems, equipment and facilities.
The purpose of this standard is to present human engineering design criteria principles, and practices to achieve mission success through integration of the human into the system, subsystem, equipment, and facilities, and achieve effectiveness, simplicity, efficiency, reliability, and safety of system operation, training and maintenance.
This standard shall be applied to the design of all systems, subsystems, equipment and facilities. Nothing in this standard shall be construed as limiting the selection of hardware, materials, or processes to the specific items described herein. Unless otherwise stated in specific provisions, this standard applies to the design of systems, subsystems, equipment and facilities for use by both men and women. This standard is not intended to be a criterion for limiting use of materiel already in the field in areas such as lift repetition or temperature exposure time.
