The Federal Aviation Administration (FAA) has published 14 CFR Part 417 Launch Safety: Lightning Criteria for Expendable Launch Vehicles, Direct Final Rule, June 8, 2011 (PDF) which amends the FAA lightning commit criteria to account for new information about the risks of natural and triggered lightning.
This action amends flight criteria for mitigating against naturally occurring lightning and lightning triggered by the flight of an expendable launch vehicle through or near an electrified environment in or near a cloud. These changes will increase launch availability and implement changes already adopted by the United States Air Force.
