Abstract : The role of the protective flying helmet has rapidly expanded from being a device for protecting the flyer from impact and noise hazards to include mounting platforms for vision enhancement devices as well as target sighting and designation systems that requires a greater degree of helmet stability and may result in greater physical exertion by the wearer. Many of the personnel now involved in the operation of these various systems are not pilots and may only fly in the aircraft for specific missions. Additionally, the requirement to wear chemical defense respirators make the fitting and refitting of these helmets time and manpower consuming. This paper describes a new helmet fitting/retention system developed at the RAF Institute of Aviation Medicine that has the potential to provide a quick and effective method of rendering a good, safe, and stable helmet fit using a minimum number of helmet sizes. The fitting/retention system also provides a relatively consistent eye position for optical systems and allows rapid donning of a chemical defense respirator. Additionally, the fitting/retention system can be used for a one-size-fits-all helmet while retaining all the above mentioned features for personnel who are only flying on specific missions and normally are not issued a flight helmet.
