NTSB Issues Recommendation A-11-023 to FAA Regarding Thunderstorm Terminology

The National Transportation Safety Board, identified by reference number DCA08MA085 and recommendation A-11-023, has issued a formal directive to the Federal Aviation Administration. This recommendation urges the agency to work directly with the National Weather Service to revise Advisory Circular 00-24B, titled Thunderstorms. The primary objective of this revision is to include clear explanations of specific terms used to describe severe thunderstorms. These terms include bow echo, derecho, and mesoscale convective system. The goal is to ensure that aviation professionals have access to precise definitions for these meteorological phenomena.
