What is the field elevation of KNDZ in feet?

• A. 1770 feet
• B. 177 feet
• C. 107 feet
• D. 150 feet

Answer: (B)

Field elevation is the altitude of the airport’s reference point above mean sea level. It’s the value shown in the airport’s data block on charts and in the Chart Supplement, and it’s used to set or compare altitudes so you know your height above the airport surface. For KNDZ, that value is 177 feet. This means the airport’s reference point sits 177 feet above mean sea level, and you can compute height above the field by subtracting 177 from your current altitude in feet MSL (for example, 1,500 feet MSL is about 1,323 feet AGL over KNDZ). The other numbers aren’t the airport’s elevation; they correspond to different data such as runway length or other chart details.
