Does the Established Airfield Elevation (EAE) vary with conditions?

Does the Established Airfield Elevation (EAE) vary with conditions?

• A. Does vary
• B. Does not vary
• C. Vary with temperature only
• D. Vary with wind

Answer: (B)

The Established Airfield Elevation is a fixed, surveyed value that represents the airport’s elevation above mean sea level and is published on charts. It serves as a stable reference for procedures, altimeter settings, and obstacle clearance calculations. Because this elevation is determined by a survey and not by current weather or wind, it does not vary with conditions. The only times it changes are when an official survey is updated or the chart is revised. So, weather-related factors like temperature or wind do not cause the EAE to change.
