Specifications

ML-STD-14721i
5.7.5 Standard console desire. (Where Table XX or Figure 30 is cited, also see Table 1.)
5.7.5.1 Dimensions. For purposes of standardization, dimensions of consoles and the units and
racks which constitute operator work stations shouid confotm to Table XX and Figure 30.
5.7.5.2 Confi~uration~ The configurations represented in Table XX and Figure 30 may not be
applicable to all design situations, Operational requi.mments may require unique design solutions.
Because of the benefits and economies inhmnt in a standard console, design should conform with the
standard configurations.
5.7.5.3 Variables. As applicable, the selected console design should accommodate required
visibility over the top of the console, operator mobility (e.g., “sit”, “stand”, or “sit-stand”), panel
space (note columns B and E in Table XX), and volume in the area below the writing surface.
5.7.5.4 Console selection. On the basis of 5.7.5.3, the configuration that will best meet the
“requirements should be selected from the five console types represented in Table XX.
5,7.6 Speeial-pumo se console design.
5.7.6.1 Horizontal wrarm-ound. (See Figure31 for example.)
5.7.6.1.1 Panel width When requirements for preferred panel space for a single seated
operator exceed a panel width of 112 cm (44 in), a flat-surface, segmented, wraparound console
should be provided to place all controls within the reach of the 5th percentile stationary operator.
5.7.6.1.2 Panel angle. The left and right segments should be angled from the frontal plane of
the central segment such that they can be reached by the 5th percentile stationary operator.
5.7.6.1.3 Dirnensions (vision over toD). Where vision over the top is required (thereby limiting
vertical panel space), the width of the central segment shall be not more than 112 cm (44 in), and that
of the left and right segments shall not exceed 61 cm (24 in).
5.7.6.1.4 Dimensions. Where vision over the top is not required, i.e., the console height may
exceed the seat height by more than 69 cm (27 in) (see Table I.), the width of the central segment shall
be not more than 86 cm (34 in); the widths of the left and right segments should be not more than 61
cm (24 in).
5.7.6.1.5 Viewing atwle. The total required left-to-right viewing angle shall be not more than
190°(see Figure 2) and should be reduced through appropriate control-display layout.
5.7.6.2 Verticai/stacked semnents. (See Figure 32 for example.)
5.7.6.2.1 Panel ,division. Where direct forward vision over tbe top of the console is not
required by a seated operator, and when lateral space is limited, the panel shall be divided into three
verticalkackd segments whose surfaces should be perpendicular to the operator’s line of sight with
little or no head movement.
5.7.6.2.2 HeiRh~,The center of the central segment should be 80 cm (31.5 in) hove the seat
Lcfcrcncc poi II(. TI K height of Lhissegment shall bc not more Lhan53 cm (21in).
