How to

How to use a circuit diagram template.

  1. 01Select a template or start from scratch

    Pick an aircraft wiring diagram template (like our Cessna 172 alternator circuit) or open a blank canvas.

  2. 02Add aircraft electrical components

    Drag and drop symbols for generators, batteries, relays, switches, and avionics from the library. Use industry‑standard icons.

  3. 03Wire and label all connections

    Draw lines between components, assign wire numbers, and add labels using the ATA chapter format.

  4. 04Validate the circuit logic

    Run real‑time checks to spot missing grounds, open circuits, or overloaded buses before finalizing.

  5. 05Export and share

    Download as PDF, SVG, or embed in maintenance manuals. Share a live link with your team for comments.

FAQ

Questions about circuit diagram templates

What is an aircraft wiring diagram?

An aircraft wiring diagram is a schematic that shows the electrical connections between components—batteries, generators, buses, switches, and loads—in an aircraft. It helps technicians trace faults and understand system behavior.

What standards are used in aircraft wiring diagrams?

Most commercial diagrams follow ATA chapter numbering (e.g., ATA 24 for electrical power) and use symbols per AS50881 or the manufacturer’s own standard. Wire numbering often includes circuit codes and segment identifiers.

Can I use these diagrams for actual aircraft maintenance?

Yes. Our templates are based on real systems and can be adapted to specific airframes. Always verify against the official Aircraft Maintenance Manual (AMM) for compliance.

How do I create a wiring diagram for a homebuilt aircraft?

Start with a blank canvas, add essential components (alternator, master solenoid, bus bars), and build your system step by step. Our wire‑management tools help keep complex harnesses legible.

What software do you support for exporting?

You can export diagrams as PDF, SVG, PNG, or import into CAD tools via DXF. We also let you share a live, editable link with collaborators.
