Head Mounted Display Design Guidelines for Future Vertical Lift Aircraft
Abstract
In rotary-wing aircraft, the purpose of a helmet mounted display (HMD) is multi-faceted. First and foremost, it provides pilot situational awareness with symbology, representing various flight parameters and positional information. An HMD can integrate symbology with pilotage imagery from aircraft sensors as well as from onboard terrain databases or other a priori databases including synthetic imagery of man-made structures and other objects. Three-dimensional symbology can conform to the terrain and mark a landing site that provides visual cueing for safe landing under brownout conditions. For attack helicopters, the HMD and integrated helmet system serves as the central display system for entire weapons systems, providing line-of-sight weapons cueing, targeting information from onboard sensors as well as from remote unmanned aircraft systems (UAS), and head tracking for slewed weapons systems. Distributed aperture systems, like the prototypes developed under the Army's Operational Pilotage for Utility and Lift (OPUL) program or the Special Operations Advanced Distributed Aperture System (ADAS) program, allow for the stitching of imagery from multiple aircraft sensors based on pilot head position, providing for increased situational awareness with a possible 360-degree field-of-regard (FOR).
