Factors contributing to pain in military helicopter pilots
It is commonly accepted that for military helicopter pilots, neck and back pain is part of the job. This pain can decrease pilot situational awareness, increase medically related downtime, and increase healthcare costs incurred due to pilots. This literature review analyzes factors that contribute …

Modeling the Impact of Helicopter Vibrations on the Musculoskeletal Health of US Army Blackhawk Helicopter Pilots
… Control System (AVCS) on reducing the impact of helicopter vibrations on musculoskeletal health. Computational analyses of a biomechanical model using OpenSim and motion capture at varying levels of vibration was conducted. This quantifies the response of the spine and the surrounding muscles …

Development of a Graphical User Interface Presenting Turbulent Airflow Over A Flight-Deck For Improved Situational Awareness For Helicopter Pilots in Challenging Wind Conditions
The intent of this study is to provide the helicopter operators a presentation of the airflow over the flight deck prior to the approach Phase Of Flight (POF). This capability has the potential to influence the decision making associated with the approach. Turbulent airflow visualization designs …

"I'd Rather Be Forgotten Than Dishonored": An Oral and Life History Project with a Vietnam Veteran
… the Vietnam era and roughly 40,000 of them as helicopter pilots in Vietnam, yet scholars are still trying to understand the Vietnam experience. There is little doubt that the war played an influential role in the lives of that generation. Yet, many Vietnam veterans refrained from talking about …

An Examination of Headset, Hearing Sensitivity, Flight Workload, and Communication Signal Quality on Black Hawk Helicopter Simulator Pilot Performance
… hearing loss and difficulty communicating in helicopter noise is well known; an appropriate way to evaluate a hearing-impaired pilot's safety risk due to hearing loss is not as well known. Previous research has studied communication ability in helicopter cockpit noise under different headsets, …

A comparison of methods for promoting geographic knowledge in simulated aircraft navigation
… a potentially dangerous problem for all types of pilots under all types of flight conditions. The problem is even more serious for helicopter pilots who often fly at low altitudes and who must be precisely aware of their location with respect to obstructions in their environment. Any pre-flight …

Perception-based synthetic cueing for night-vision device rotorcraft hover operations
Helicopter flight using night-vision devices (NVDs) is difficult to perform, given evidence by the high accident rate associated with NVD flight compared to day operation. A mishap analysis of NVD-related helicopter accidents was conducted which found approximately 70% of the accidents attributable …
