Producing aircraft wiring layouts and routeings

This standard identifies the competences you need to produce aircraft wiring layouts and routeings, in accordance with approved procedures. It covers both fixed wing and rotary winged aircraft. You will be required to use appropriate drawings, standards and specifications to produce the wiring layouts and routeings. You will be expected to draft loom formats, transfer data, process data, create loom boards and determine the lengths and shapes of looms.

Your responsibilities will require you to comply with organisational policy and procedures for the wiring layout activities undertaken and to report any problems with the activities, materials, tools and equipment used that you cannot personally resolve, or that are outside your permitted authority, to the relevant people. You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out.

Your underpinning knowledge will provide a good understanding of your work and will provide an informed approach to applying aircraft wiring layout procedures. You will understand the production requirements for the wiring layouts and routeings, and will know about the various wire types and gauges, and the tools, terminations and techniques, in adequate depth to provide a sound basis for carrying out the activities, correcting faults and ensuring that the wiring layouts and routeings are to the required specification.

You will understand the safety precautions required when carrying out the wiring layout and routeing activities. You will be required to demonstrate safe working practices throughout and will understand the responsibility you owe to yourself and others in the workplace.

5. how to interpret first and third angle drawings, imperial and metric systems of measurement, workpiece reference points and system of tolerancing
6. how to carry out currency/issue checks of the drawings and specifications you are working with
7. the cableform/loom layout to be produced and its function within the particular system
8. how to access and retrieve information from CAD systems
9. how to access and retrieve information from company document management systems
10. why tool/equipment control is critical and what to do if a tool or piece of equipment is unaccounted for on completion of the activities
11. the manufacturing requirements of aircraft wiring cableforms and looms
12. how information should be presented (to include process sketches and computer reports)
13. the extent of your own responsibility and to whom you should report if you have problems that you cannot resolve
