USN/USMC Ejection Seat Equipped Aircraft Anthropometric Accommodation

摘要

USN/USMC ejection Seat equipped aircraft anthropometric accommodation guidance is outdated and undocumented. Recent reassignments of aviators within the USN/USMC have highlighted an area where operational dollars could be saved by assigning candidate aviators to a correct and safe pipeline. These issues were revealed during the course of NAVAIRSYSCOM (PMA-202) Aircrew Accommodation Expansion Program where AIR 4.6, Patuxent River was tasked to perform a baseline accommodation assessment of in-service USN/USMC aircraft. The methods used in the program approach were different than procedures historically used to determine USN/USMC aviator suitability and to verify cockpit design. A multivariate statistical approach was employed and served as the basis for determining the safe accommodation envelope. The revised guidance suggested here accounts for: (1) The location of the scat with respect to the competing variables that drive the seat location; (2) The operational use of the anthropometric accommodation guidance and pipeline relational charting; and (3) The cost avoidance associated with inappropriately assigning aviators. These revised guides help to define the acceptable range of aircrew anthropometric dimensions that must be satisfied to achieve safety of flight and mission of effectiveness.
