11.2.1.1-2 Location of Controls

Controls should be located within the reach radius of the 5th percentile female without stretching, while the lowest controls should be within the lowest reach of the 95th percentile male without bending or stooping.

Additional Information: Table 11.4 provides data on reach for females and males. Controls may be placed somewhat higher on consoles with shallower or more steeply angled benchboards, which allow the shoulder reference point to be closer to the back of the benchboard and to the vertical panel.0700

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.
