This document presents human factors issues that should be considered in the design and evaluation of air traffic control (ATC) systems and subsystems. The checklist is a companion document to Human Factors in the Design and Evaluation of Air Traffic Control Systems. The goal of this checklist is to point air traffic controllers and other operations specialists to questions that they may wish to consider in their evaluation of new systems or subsystems, or a new component of an existing system. Some checklist items may be used as a rough filter for known design flaws; others are more appropriate for group discussion. The numbers in parenthesis at the end of each checklist item refer to the section in Human Factors in the Design and Evaluation of Air Traffic Control Systems that discusses the issue. This mapping allows the checklist user to learn about the basis for the item, why it is important, and the implications of compromise. Checklist items marked with an 'E' indicate items that must be assessed with equipment and/or by referring to the specifications documentation.
