GA Wire Helper FAQ

No. GA Wire Helper is a one-time purchase: you pay once and it’s yours. There’s no monthly or yearly fee, no renewal, no account to keep active and nothing to cancel. The version you buy keeps working for as long as you use it, even offline.

Very. Builders of kit and plans-built aircraft design their own electrical systems, often with no manufacturer wiring diagram to work from. GA Wire Helper lets you plan the whole system before building it — size wires and breakers against AC 43.13-1B, check loads and voltage drop, and print the parts list, pinouts, wire list and wire labels you build the harness from — and leaves you with an accurate wiring diagram for the aircraft's records and future troubleshooting. GA MX Helper isn't needed for this.

No. Unzip the download and double-click the GA Wire Helper icon (Mac or Windows) — it opens the app in your web browser. Nothing to install, no account, no login. Chrome or Edge is recommended; the GA MX Helper link and USB laser marking need one of those two.

Yes — anywhere Chrome or Edge runs. It's built for a laptop or desktop screen.

Only for a moment when you first activate your license key. Drawing, lists and load analysis all work offline after that.

On your own computer — in the browser, and (if you link GA MX Helper) as files in a Wiring Diagrams folder next to GA MX Helper's data. Nothing is sent to us. Use Export → Project file for a separate backup.

Yes, built in — press ? Manual in the app. It covers every tab, the wire-numbering systems, the symbol guide, and laser marking, with pictures.

No. GA Wire Helper works completely on its own. Linking the two is optional.

GA Wire Helper reads your aircraft list, equipment and company info from GA MX Helper, and saves each project and PDF to that aircraft's folder under Wiring Diagrams. In GA MX Helper, each aircraft profile gets a Wiring Diagrams tab listing them, with a "+ New Wiring Diagram" button.

Open GA Wire Helper with its launcher icon (in Chrome or Edge), then choose Settings → GA MX Helper link → Use GA MX Helper's folder. Both launchers share one local server, so the two apps can find each other wherever their folders are. The manual walks through it step by step.

No. It only reads them. It never writes to GA MX Helper's data file.

No — on purpose. Pinouts come from the installation manual you're working to, and the app makes them fast to enter: paste a pin table straight out of a manual or spreadsheet, save the part to your library, and it's there for every future project.

Your choice, per project: MIL-W-5088 style (function, circuit, segment and gauge, e.g. P8A20) or airline bundle-wire-gauge style (e.g. W123-1234-22). When adding to factory wiring, reserved 901/9001 ranges keep your numbers from clashing with the manufacturer's.

No. It's a drafting and recordkeeping aid. It helps you document an installation done to acceptable or approved data — AC 43.13-1B, the manufacturer's installation manual, an STC — but it isn't approved data itself, and its calculations are estimates based on what you enter.

PDFs of the diagram, notes, connection chart, component list, parts list, wire lists, pinouts and load analysis — as a work copy or a 337 / logbook copy — on Letter, Legal, 11×17, A4 or A3. Also SVG, PNG and CSV exports, and a project backup file.

Three ways: sticker labels on Avery sheets or label tape; heat-shrink ID sleeves marked with a small diode laser; or directly on the wire where the wire manufacturer and your approved data allow it. A batch checklist tracks what's done.

A GRBL 1.1 engraver (Arduino Uno with a CNC Shield V3 and a blue diode laser) — the same hardware LaserGRBL uses. The app can drive it over USB in Chrome or Edge, or export G-code for LaserGRBL. The built-in manual includes build notes for a low-cost marker and the WM-1 feed-through wire marker, plus the laser-safety steps to read first.

$49.99, one time — or included in the Complete Bundle with GA MX Helper and both of its add-ons. See Pricing.

No — each app has its own key. The exception is the Complete Bundle, whose single key unlocks both apps.

Yes. Deactivate it under Settings → License & terms, then activate the same key on the new computer. Export your projects first and open them there.

Like GA MX Helper, it's a digital product delivered immediately, so sales are final. If something isn't working, contact us first — we want to fix it.
