Paper Abstract

The head-mounted display (HMD) presents flight, navigation, and weapon information in the pilot's line-of-sight. The hMD was developed to allow the pilot to retain aircraft and weapon information while looking off-boresight. Recent work has produced an HMD design guide and a draft Aeronautical Design Standard to provide guidance for the development and testing of HMD designs for rotorcraft applications. Several key issues have been identified: display coordinates, data latency, field-of-view, and image resolution. ADS-46 will outline the display design process in terms of the documents required to be prepared for several program mile-stones, including the operational requirements document, the mission analysis and information requirements report, and crew station design document, and the test and evaluation master plan. The major shortcoming in existing display standards and specification is the absence of objective performance criteria. This has led to an over-reliance on subjective opinion-based testing. The proposed ADS-46 will require the development of objective, mission-based performance objectives and test to ensure that these objectives are met. Several new tests are included: an aggressive visual tracking task to identify deficiencies in display latency; a spatial awareness test; a geographic awareness test; and a subjective performance assessment test.
