What does Minimum Vectoring Altitude (MVA) describe?

• A. An IFR altitude lower than the minimum en route altitude (MEA) that provides terrain and obstacle clearance.
• B. An altitude used for standard instrument departures during vectoring.
• C. The highest altitude allowed within a terminal area.
• D. A cruising altitude where weather minimums are determined.

Answer: (A)

Minimum Vectoring Altitude describes the altitude ATC uses to keep an IFR aircraft safe when radar vectors are being provided in a specific area. It’s the lowest altitude in that radar-covered sector at which obstacle and terrain clearance is assured while controllers guide you with radar,” typically to the final approach path. That’s why it’s described as lower than the MEA in this context: the vectoring segment relies on ATC’s radar guidance to steer you to the approach, rather than staying at the en route altitude that guarantees navigation signal reception along a published route. If you’re outside radar coverage or outside the MVA, you’d rely on the higher MEA for obstacle clearance and navigation reliability. This concept isn’t about standard instrument departures, maximum terminal-area altitude, or weather minimums, which is why the other options don’t fit.
