What determines the field elevation for an airport?

The determination of field elevation for an airport is based on a defined standard that is often represented in aviation charts, including Jeppesen charts. Field elevation is the highest point of an airport's landing area, measured in feet above sea level. The Jeppesen chart provides critical information, including the chart's title area, which typically indicates the field elevation like other important airport data.

This is particularly useful for pilots, as knowing the field elevation is essential for various flight operations, including takeoff and landing calculations. It allows for better planning regarding aircraft performance in relation to weather conditions and geographical features.

While weather conditions can affect flying conditions, and geographical location can play a role in the overall environment of the airport, the specific field elevation is provided in chart data rather than derived from these factors. Flight operations are guided by this information, but they do not determine the airport's field elevation directly. Thus, the most accurate answer is found in the Jepp chart where this measurement is explicitly listed.
