The formula to calculate the Variation of Acceleration due to Gravity on Altitude is:
\[ gv = [g] \left(1 - \frac{2 \cdot h}{[Earth-R]}\right) \]
Variation of acceleration due to gravity is inversely proportional to the square of the radius of the earth, and it varies with latitude due to the shape of the earth. Altitude, like elevation, is the distance above sea level. Areas are often considered "high-altitude" if they reach at least 2,400 meters (8,000 feet) into the atmosphere.
Let's assume the following value:
Using the formula:
\[ gv = [g] \left(1 - \frac{2 \cdot 33.2}{[Earth-R]}\right) = 9.80654779302141 \text{ m/s²} \]
