What is the max field elevation for takeoff and landing?

• A. 7,000 ft
• B. 8,400 ft
• C. 9,200 ft
• D. 6,500 ft

Answer: (B)

Field elevation is the airport’s altitude above mean sea level. As elevation increases, the air becomes thinner, which reduces engine power, propeller efficiency, and the wing’s lifting ability. That’s why aircraft have published takeoff and landing performance within a specific range of field elevations. In this context, the performance data used to determine safe takeoff and landing distances are valid up to 8,400 feet. Therefore, the maximum field elevation for takeoff and landing is eight thousand four hundred feet, since beyond that the standard data don’t apply and different calculations or data would be needed.
