Neurophysiological Measures of A-10 Workload during Simulated Low Altitude Missions.

Abstract

Eye movements and evoked responses were used to test pilots' reactions to emergency conditions while flying simulated A-10 missions. Two types of stick jam or other minor emergencies occurred during a pull up maneuver. Oculometer and behavioral data were collected to measure the pilots' responses to these situations. Evoked responses to single tones that were presented one second after the onset of each emergency were used to assess whether or not the pilots were yet aware of the presence of the emergency. The oculometer data showed that the pilots very efficiently responded to the emergencies with a few appropriately directed eye movements. The correct indicators and response areas were looked at and the proper responses to correct the emergency were rapidly made. The evoked response data supported the oculometer data. Movement artifacts during the evoked response analysis epochs indicated that the pilots quickly detected the emergency situations, in many cases this happened so fast the they were moving by the time the tone probe was presented. Subjective questionnaire data showed that the pilots ranked the jam conditions as more difficult to deal with than the minor emergencies. The pilots also felt confident that they could handle the situations that occurred. (Author)
