Enter the ground speed (MPH) into the Pivotal Altitude Calculator. The calculator will evaluate the Pivotal Altitude.

## Pivotal Altitude Formula

The following two example problems outline the steps and information needed to calculate the Pivotal Altitude.

PA = GS^2 / 15

Variables:

- PA is the Pivotal Altitude (ft)
- GS is the ground speed (MPH)

To calculate the pivotal altitude, square the ground speed, then divide the result by 15.

## How to Calculate Pivotal Altitude?

The following steps outline how to calculate the Pivotal Altitude.

- First, determine the ground speed (MPH).
- Next, gather the formula from above = PA = GS^2 / 15.
- Finally, calculate the Pivotal Altitude.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

ground speed (MPH) = 150

PA = GS^2 / 15** **= ?
