1   The data in this table are from MIL-STD-1472G, Appendix B (DoD, 2012). MIL-STD-1472G gives separate values for general forces, Army aircrews, and Air Force pilots. This table contains the values for general forces. The MIL-STD contains additional anthropometric data not represented in this table. Applicants may use alternative values if a design is intended for a population for which these data are not representative or if updated data are available.

2   Measured from wall to tip of right index finger, with arm extended horizontal to floor, both shoulders against wall.

3   Measured as stated above, except right shoulder extended as far as possible with left shoulder against wall.
