Can ATC vector an aircraft below the Minimum Safe Altitude (MSA)?

The correct answer indicates that an Air Traffic Controller (ATC) can vector an aircraft below the Minimum Safe Altitude (MSA) as long as it is above the Minimum Vectoring Altitude (MVA).

The distinction between MSA and MVA is crucial. MSA is designed to provide a safe altitude above obstacles for aircraft in a particular area, used for navigation and approaches. In contrast, MVA is set at a lower altitude specifically for vectoring purposes, and it ensures a safe clearance over terrain and obstacles within a specific sector of airspace.

When ATC provides vectors, they operate with the assurance that the aircraft will remain above the MVA, which accounts for safety over the terrain and provides leeway for maneuvering. Thus, as long as the flight is at or above this minimum altitude, ATC has the authority to issue vectors even if that requires altitude adjustments that take the aircraft below the MSA. This allows for more flexible traffic management while ensuring safety protocols are still prioritized.

This context clarifies why the assertion that ATC can vector an aircraft below MSA, provided it remains above MVA, is legitimate and aligns with aeronautical regulations.
