What determines the field elevation for an airport?

The field elevation for an airport is primarily determined by its geographical location, which refers to the physical elevation of the airport above sea level in relation to the surrounding terrain. While weather conditions and flight operations may influence aspects of airport management and planning, they do not directly determine the elevation of the airport itself.

The reference to the "top left corner of a Jepp chart" implies that Jeppesen charts display critical information about an airport's location, including its field elevation, but field elevation is ultimately derived from its geographical position and the elevation of the land upon which the airport is built. Therefore, the field elevation is a static measure tied to the airport’s location and does not fluctuate based on weather or operational factors.
