Which agency typically establishes and regulates Minimum Vectoring Altitudes in airspace?

• A. National Transportation Safety Board
• B. Federal Aviation Administration
• C. Air Traffic Safety Organization
• D. International Civil Aviation Organization

Answer: (B)

The Federal Aviation Administration (FAA) is responsible for establishing and regulating Minimum Vectoring Altitudes (MVAs) in airspace. MVAs are the lowest altitudes to which an aircraft can be safely vectored by air traffic control. The FAA determines these altitudes based on various factors, including terrain and obstructions, ensuring that aircraft receive safe clearance above obstacles while being directed by air traffic controllers. This regulatory function is crucial for maintaining safety in the National Airspace System as it allows controllers to provide efficient and safe guidance to aircraft in a crowded airspace environment.

Other agencies listed, such as the National Transportation Safety Board, primarily focus on investigating accidents and making safety recommendations, rather than directly regulating airspace altitudes. The Air Traffic Safety Organization is not a recognized entity involved in this specific regulatory aspect within the U.S., and while the International Civil Aviation Organization sets guidance principles applicable internationally, the direct establishment and regulation of MVAs is the specific role of the FAA within the United States.
