The objective is to extend computer aided design practices into the creation and update of schematic and wiring diagrams, together with an automatic interface with a computerized wire handling system, in order to improve efficiency by reducing drawing errors and lea

12、e following definitions have been used by the working party. 2.0.1. Theoretical Diagram A simplified diagram, drawn by system, which sets out the function logic for the system to enable the operation of the system to be easily understood. It makes no attempt to show connections which are required fo
13、r production purposes. 2.0.2. Schematic Diagram An enlarged theoretical diagram which covers the inter- faces between several systems and can include simple schematic representation of an associated mechanical system, It is required to enable the operation of the interface functions and systems oper
14、ation to be readily understood. It is also required to provide an aircraft operator with sufficient information for trouble shooting without additional instructions. 2.0.3. Wiring Diagram A diagram which shows the physical installation features of the system in the aircraft such as the physical loca

In addition it should show complete details of the interconnecting wires such as wire type, size and coded ter- minal connections. It is used
16、a) to provide the necessary information for production departments to build the aircraft and b) to enable the aircraft operator to service and maintain the aircraft wiring wheh in service use.

21、Tliese are in the areas of technical publications and the sequence of carrying out the various activities. 4.1. Basic Electrical Drawing System The existing flow of data is shmn schematically in Figure 1. Technical data for the wiring diagram originates from design engineers in the form of a hand dr
22、awn schematic or theoretical diagram. At this stage a preliminary failure mode and effect analysis is carried out and the diagram amended as necessary. The schematic will be annotated with requisite ir! stallation design data such as unit load characteristics, minimum recommended circuit protection
23、device rating to match the load, and where necessary particular connector pin allocations required to meet the failure analysis. This schematic or theoretical diagram is then passed (a) to tracers who prepare an ink master copy for use by the Technical Publication Department in preparing a customer
24、Wiring Manual and (b) to the installation design group who will create and hand draw the wiring diagram for that system, adding the necessary production breaks, positional coding, equipment coding and the interconnkcting wires, specifying type, rating, wire code and cohnection caie details. When com
25、plete, these also are passed to tracers for preparation for use by the Technical Publications Department in preparing customer Wiring Manuals. The schematic and wiring diagrams are drawn on special sheets to specified guide lines to enable a suitable reduction to be made to provide 11 x 17 inch page
26、s for the customer wiring - manual. At this stage of cohpletion of the wiring diagram and before formal issue, the relevant wire and equipment data is manually extracted from the diagram and prepared as input to the comput erized wire handling syn fig. 14.
