FAARFIELD (FAA)
Standard airport pavement thickness design software developed and distributed free by the U.S. Federal Aviation Administration (FAA) -- implements the FAA AC 150/5320-6G pavement design methodology using layered elastic analysis and the ACR/PCR pavement-strength reporting method; the mandatory tool for any U.S. airport pavement engineer working on FAA-funded airport projects, with companion backcalculation (BAKFAA) and runway-exit-design (REDIM) software.
Solid -- the FAA-mandated, free standard for airport pavement design with layered elastic analysis and ACR/PCR strength reporting; zero cost, zero lock-in, and accompanied by free companion tools (BAKFAA for backcalculation, REDIM for runway exit design), but it is a desktop-only tool with no API/CLI (RF2) and the airport-specific scope limits use to pavement engineers on FAA-funded projects.
