Minimum Vectoring Altitude (MVA) is used in which airspace condition?

Minimum Vectoring Altitude (MVA) is used in which airspace condition?

• A. In well-covered radar airspace.
• B. In non-radar or degraded radar coverage areas.
• C. Only during ground traffic control.
• D. Only for helicopter operations.

Answer: (B)

Minimum Vectoring Altitude is the baseline altitude that ensures obstacle clearance when radar coverage is incomplete or degraded. The idea is that in areas where radar does not reliably cover the airspace, controllers cannot depend on radar to provide precise separations or vectoring. By using a defined MVA, pilots are kept at a safe altitude above terrain and obstacles while radar coverage is weak or unavailable, allowing safe radar vectoring when possible. When radar coverage is good, controllers can vector aircraft at lower altitudes and rely less on this constraint, so MVA isn’t a limiting factor there. This concept is specifically about radar coverage conditions, not about ground control or a particular type of aircraft like helicopters.
