In the first part of the reported research, 12 instrument-rated pilots flew a high-fidelity simulation, in which air traffic control presentation of auditory (voice) information regarding traffic and flight parameters was compared with advanced display technology presentation of equivalent information regarding traffic (cockpit display of traffic(More)
BACKGROUND General aviation (GA) accident statistics indicate that visual flight rules (VFR) flight into instrument meteorological conditions (IMC) is a major safety hazard. However, little research has been conducted to identify the factors that influence VFR pilots' decisions to risk flying into deteriorating weather. The purpose of the present study was(More)
ARL 1 ABSTRACT Two models of information acquisition in visual scanning are described. A descriptive model identifies the role of event salience, effort, expectancy and value in influencing where and when people look at different channels to sample information in dynamic environments. An optimal prescriptive model accounts for the role of expectancy and(More)
Visual flight rules (VFR) flight into instrument meteorological conditions (IMC) is a major safety hazard in general aviation. In this study we examined pilots' decisions to continue or divert from a VFR flight into IMC during a dynamic simulation of a cross-country flight. Pilots encountered IMC either early or later into the flight, and the amount of time(More)
A computational model of attention and situation awareness (SA) was developed and used to predict pilot errors in the task of taxiing from runway to terminal. The model incorporates a low-level perception/attention module and a higher-level belief-updating module. Attentional scanning is controlled by bottom-up and top-down processes, with the effectiveness(More)
Visual Flight Rules (VFR) flight into Instrument Meteorological Conditions (IMC) is a major safety hazard within general aviation. In this study, pilots' decisions to continue or divert from a VFR flight into IMC during a dynamic simulation of a crosscountry flight were examined. Pilots encountered IFR conditions either early or later into the flight and(More)
The present study investigated the use of two automated aids of different reliabilities in a luggage screening task. A Direct Cue consisting of a green circle around a potential target directs attention to a specific part of the luggage image, while an Indirect Cue, consisting of a green border around an image determined to have a target, does not. Direct(More)
