Integration of a Vestibular Model for the Disorientation Research Device Motion Algorithm Application.

Spatial disorientation (SD) remains a leading cause of Class A mishaps and fatalities in aviation. Motion-based flight simulators and other research devices provide the capacity to rigorously study SD in order to develop effective countermeasures. By applying mathematical models of human orientation perception, we propose an approach to improve control algorithms for motion-based flight simulators to study SD.

In-flight hypoxia events in tactical jet aviation: characteristics compared to normobaric training.

Introduction: Hypoxia continues to be a significant threat in military aviation. In an attempt to counter the hypoxia threat, military jet aviators receive periodic training using a reduced oxygen breathing device (ROBD). This study explored the characteristics of in-flight hypoxia events among tactical jet aviators and compared reported symptoms to those experienced during ROBD training.

Normobaric hypoxia training: the effects of breathing-gas flow rate on symptoms.

Introduction: The U.S. Navy has replaced segments of refresher low-pressure chamber instruction with normobaric hypoxia training using a reduced oxygen breathing device (ROBD).

Mask-on hypoxia training for tactical jet aviators: evaluation of an alternate instructional paradigm.

Introduction: Hypoxia familiarization instruction has been an integral part of military aviation training for more than 60 yr. Traditionally, aircrew learn hypoxia recognition while being exposed to hypobaric conditions in a low-pressure chamber (LPC). A training device has been developed that induces hypoxia using mixed gas delivered through an aviator's oxygen mask.
