NASA-STD-4010A establishes common Lightning Launch Commit Criteria (LLCC) for avoidance of natural and triggered lightning to launch vehicles during ascent that are developed by the Lightning Advisory Panel (LAP) for United States space launch.

As the definitive document for the most up-to-date LLCC in support of launches, this Standard has been adopted for use by other Federal Government agencies involved with spaceflight operations, including the Department of Defense (DoD) and the Federal Aviation Administration (FAA). The United States Space Force (USSF) and FAA regulations refer to this publication as a common standard for criteria intended to protect against the hazards associated with natural and triggered lightning.
