Predicting astronaut performance when choosing where to land on the Moon, or the landing point designation task, is difficult. Human judgment and decision making for this application is not well-characterized. To address this knowledge deficiency, an experiment was designed to replicate the landing point designation task in both ideal and poor landing(More)
Despite two decades of manned spaceflight development, the recent thrust for increased human exploration places significant demands on current technology. More information is needed in understanding how human control affects mission performance and most importantly, how to design support systems that aid in human-system collaboration. This information on(More)
Raja Parasuraman, the father of Neuroergonomics (the crossroads of Ergonomics and Neuroscience, Figure 1) has opened the doors to new discoveries and techniques for advancing understanding of human behavior with the underlying brain mechanisms (Parasuraman, 1998). As of his death in 2015, a precise and objective definition of the concept of mental workload(More)
The objective of this paper is to examine current literature and to compile a guideline for integrating human factors principles into systems engineering. Each of the four suggested design stages — requirements acquisition, concept generation, preliminary, detailed — is characterized by a short description of the systems engineer's and the(More)
Project Modern Taxiing (MoTa) studies the impact of future taxiing technologies such as Datalink and autonomous taxiing tugs on airport taxiing operations and air traffic controller workload. Seven air traffic controllers were asked to manage ground traffic in two scenarios that imposed medium and high levels of workload with three different degrees of(More)
—Experimentally derived data was extrapolated to compare the lunar landing performance of human pilots to that of an automated landing system. 12 The results of this investigation are presented. Overall, the pilots performed equal to or better than the automated system in 18% of the relevant cases, but required more fuel. Pilot site selections were further(More)
