Which color indicates the airport elevation is above 9,800 ft?

• A. Red
• B. Amber
• C. Green
• D. Blue

Answer: (A)

Color coding is used to quickly convey elevation categories for airports, and red is the flag for airports with elevations above 9,800 ft. At high elevations, air density is thinner, which affects takeoff and climb performance and can require additional planning (longer takeoff roll, higher true airspeeds, and potential oxygen considerations). This is why the system uses red to stand out and prompt you to prepare accordingly. The other colors represent different elevation ranges or conditions, but none indicate elevations above 9,800 ft.
