Flight Deck Information Automation: A Human-in-the-Loop In-Trail Procedure Simulation Study

Information automation systems are generally intended to support pilot tasks and improve flightcrew awareness and decision making, but not to directly control the aircraft or its systems. As a result these systems do not include cases where automation decisions and actions directly affect the aircraft performance, flight path or systems. Next Generation Air Transportation System (NextGen) operational concepts and technologies will dramatically affect both the types and amount of information available on flight decks. Much of that information will be produced by flight deck information automation systems that collect, process, and present that information to the flightcrew. It is therefore important to understand the human factors characteristics of information automation systems and identify human factors issues specifically related to information automation. This paper presents an investigation of two information automation characteristics (functional complexity and automation visibility) using prototype oceanic In-Trail Procedures (ITP) display systems. The outcome will be used to develop and iterate recommendations for design and evaluation of information automation systems that will mitigate the identified human factors issues
