The maximum terrain elevation in the Minot to Audubon Lake area is what height in feet MSL?

• A. 1,900
• B. 2,000
• C. 2,500
• D. 3,000

Answer: (C)

Understanding terrain elevation data helps you plan safe altitudes around terrain. The maximum terrain elevation is the highest point of ground within the area, expressed in feet above mean sea level (MSL). In the Minot to Audubon Lake area, the tallest point is 2,500 feet MSL, so that is the maximum terrain elevation there. This value is what you’d use to ensure you maintain adequate clearance from terrain when plotting a flight path. The other numbers are lower elevations within the area and do not reflect the highest point.
