What is the MSA over non-congested areas?

• A. 1,000 feet above the tallest obstruction
• B. 500 feet above the tallest obstruction
• C. 1,500 feet above the ground
• D. At least 1,000 feet above ground level

Answer: (B)

The Minimum Safe Altitude (MSA) is the lowest altitude that provides a safe clearance above terrain and obstacles during flight. In non-congested areas, the standard for MSA is typically set at a minimum of 500 feet above the tallest obstruction within a specific radius. This altitude ensures safe vertical clearance over the highest objects, thus reducing the risk of collisions with obstacles while accounting for varying terrains. In contrast to the other options, which suggest higher altitudes, the benchmark of 500 feet specifically applies to non-congested areas, where the density of obstacles is lower, making it the appropriate choice without the need for added safety margins required in more congested environments.
