are similarly numbered but with the prefix “H”. All connections
and circuit components in a given figure, that are not indicated
as optional, are provided when that figure is specified by the
J-drawing. Options are indicated on the figures by a letter or
letters inside a double circle.
An option is defined when alternative connections or circuit
components are possible. T-drawing options are called Wiring
options for connection alternatives and Apparatus options for
component differences. Where possible, T-drawing options are
derived directly from those defined on the SD-drawing, using
the same lettering scheme (see below). Options which are found
on the T-drawing, but not on the SD, always include the prefix
“H”. Optional wiring and hardware is provided only when the
associated options are specifically called for by Table A of the
J-drawing.
SD-drawings
The SD-drawing is the source for the circuit information that
describes a product. The connectivity and options shown on the
T-drawing are based on the SD. The parts on the J-drawing
stocklist which are circuit components are documented on the
SD. Mechanical parts, wire colors, wire routing and cable
harnesses, however, are not necessarily shown on the SD.
The SD-drawing package is usually sectionalized, similar to the
J-drawing, as follows:
A-sheets are cover sheets including Title Block, Supporting
Information, Sheet Index, Option Index. All of this information
is similar in format to that on T- and J-drawings.
B-sheets contain the Functional Schematics (FSs).
C-sheets list the Apparatus Figures (APP FIGs) (i.e. circuit
component lists).
D-sheets contain drawing notes categorized as Circuit Notes
(numbered 101 to 200), Equipment Notes (numbered 201 to
300) and Information Notes (301 to 400). Certain standard notes
of particular interest are:
Note 102: Feature & Option Table which describes each option
letter, is often duplicated in the T-drawing engineering notes.
