MRA stands for

• A. Minimum Reception Altitude
• B. Maximum Reception Altitude
• C. Minimum Runway Altitude
• D. Minimum Required Altitude

Answer: (A)

Minimum Reception Altitude is the lowest altitude along a route segment at which a navigation aid’s signal can be received reliably. This ensures you can still determine your position using that aid as you fly, accounting for terrain and distance from the facility. If you drop below this altitude, the signal may fade or be lost, making navigation with that particular aid unreliable. This term is distinct from concepts like runway elevation or general altitude requirements for an approach, which relate to different aspects of flight planning. You might see other terms that describe obstacle clearance or signal coverage in different contexts, but Minimum Reception Altitude specifically addresses ensuring dependable NAVAID reception along a published route.
