11.3.1.2-1 Vertical Viewing Angle

The vertical viewing angle from the eye point of the user to the center of the visual display image area should be in the range between minus 40 degrees and 0 degrees relative to the horizontal LOS. Additional Information: Preferably, the center of the visual display screen image area should be located between a minimum of minus 25 degrees and a maximum of minus 15 degrees vertical relative to the eye point of the user in the normal working posture. The location of the visual display device should be measured relative to the eye point of the user. For convenience in measuring viewing angles and distances, the bridge of the nose may be substituted as a reference location for the eye point of the user.6
