Put the wires in your cockpit

Free wire-hazard waypoints for your panel or EFB, one file per state or province. Pick where you fly and what you fly with, and you get the right file and the steps to load it.

Choose a state or province and a device to see your download and install steps.

⚠ ADVISORY ONLY — NOT FOR NAVIGATION. These waypoints do not replace current charts, your aircraft's own obstacle database or see-and-avoid. The data is known to be incomplete, especially for low distribution lines: the absence of a marker does not mean the absence of wires. No panel or EFB raises an obstacle alert from user waypoints; they are display only.

What's in the files

Power lines and cables that cross water: mapped over-water spans (one point at mid-span), river and lake crossings, cable ferries and cableways, lidar-confirmed crossings and the FAA's own wire obstacles over water. Every hazard has the same six-character name on every device, and it keeps that name when you update.

Panels hold a limited number of user waypoints, so long lists are cut by priority: tier A before B before C, wires that are not in the FAA obstacle file before charted ones, confirmed crossings before lidar-only finds, then higher voltage and longer spans. The short text reads WIRE 115KV A UNCHTD: voltage, confidence tier, and UNCHTD when the wire isn't in the FAA obstacle file. Heights only appear when surveyed. Elevation fields are left blank on purpose.

See a wire we're missing? Report it; pilot reports close the gaps fastest.
