# ESDU Challenge: Geopotential Height

In this series from IHS ESDU, challenge questions will be posted for the community. Some questions may require calculations and others are general knowledge questions.

Here's this week's question:

An aircraft is flying at a geometric height of 10000 m at a geographic latitude of +10°. What is the geopotential height?

And the answer is:

9959 m. ESDU 77022 contains the relationship for calculating the geopotential height for a given geometric height and geographic latitude.

Visit the IHS ESDU website for more information about the validated design methods, or to request a trial subscription.

It does depend on the exact location on Earth too, doesnt it?

Just a bit higher than the highest mountain available. Watch out for wind conditions.
