The information content of cockpit displays

Abstract

Cockpit displays have been described by name and by pictures or diagrams in which each indicator element is named. The names of the elements themselves are frequently not precisely defined. Within a single display and among the several displays on a panel it has been difficult to identify redundancy and equivalence of information. This paper presents a system of definitions and notation of display information elements. The system is based on a synthesis of (1) engineering definitions related to equations of motion and (2) human performance data which relate equivalence and sufficiency of displayed parameters.<>
