NAVAIRINST 4120.11
part number information for all equipment, components and parts
should be accessible at any point in the presentation of WP
text, tables and illustrations, when necessary, for the purpose
of identification and parts ordering.
A.4.7.6 Equipment panel markings (placarding). Reference should be
made to panel markings and switch positions exactly as marked on
the equipment. However, symbols on panel markings should be
spelled out when the software, composing equipment, cannot
produce them or printers used in producing the manual, such as
the symbol for ohm, infinity, etc.
A.4.7.7 Metric and U.S. standard measurements. Unless specified
otherwise by the acquiring activity, all measurements should be
expressed in both U.S. standard units (e.g., ounces, pounds,
gallons, inches, feet, knots, miles, etc.) and metric units.
U.S. standard measurements should be followed by the metric
conversion in parentheses unless the equipment, instrument, or
tool, etc., is calibrated in metric units. In that case, metric
units should be first, followed by the U.S. standard units.
(For example, "169.5 Nm (125 lb-ft)".)
A.4.7.8 Temperature. Reference should be made to temperature
readings as calibrated on the equipment. If other than
Fahrenheit, the equivalent in Fahrenheit should follow in
parentheses. General temperature references, such as room
temperature, should be given in degrees Fahrenheit (for example,
78°F).
A.4.7.9 Other IETMs. When it becomes necessary to reference to
other work packages, descriptive information, maintenance tasks,
or other data contained in another IETM, it should be by the
IETM number, as a minimum. The reference should be linked when
the referenced data is on the same CD or within the CD set for
the system.
A.4.7.10 Tables. Tables should be linked to the appropriate text
and displayed when they do not already appear in the graphics
client area on the user's EDS or viewer.
A.4.7.11 Figures. Figures should be linked to the appropriate text
or index number and displayed when they do not already appear in
the graphics client area on the user's EDS or viewer.
A.4.7.12 Index numbers. Unless specified otherwise by the
acquiring activity, figure and index numbers should be used in
text to identify items and parts on illustrations. For example,
41 Enclosure (4)
