How do I generate runway linework for an Airport Layout Plan (ALP)?

Enter the runway end coordinates and design parameters, and AvPlot's Runway Linework Generator produces centerline, edges, threshold markings, and blast pads as scaled CAD geometry. Export the result as DXF for AutoCAD or MicroStation, or KMZ for Google Earth. Geometry follows FAA AC 150/5300-13B runway and shoulder standards.

What formats can I export runway linework in?

DXF (CAD linework) and KMZ (Google Earth). A 3D DXF option also layers Part 77 imaginary surfaces and obstacle clearance (OCS) surfaces over the runway.

Does the runway linework include Part 77 surfaces?

Yes. The 3D DXF export adds the Part 77 primary, approach, transitional, horizontal, and conical surfaces, with the approach surface anchored 200 ft beyond the threshold per 14 CFR 77.19.
