Enter the change in altitude (ft) and the change in horizontal distance (ft) into the Calculator. The calculator will evaluate the Average Rate Of Descent.

## Average Rate Of Descent Formula

ROD = CA / CD

Variables:

- ROD is the Average Rate Of Descent (ft/ft)
- CA is the change in altitude (ft)
- CD is the change in horizontal distance (ft)

To calculate the Average Rate Of Descent, divide the change in altitude by the change in distance.

## How to Calculate the Average Rate Of Descent?

The following steps outline how to calculate the Average Rate Of Descent.

- First, determine the change in altitude (ft).
- Next, determine the change in horizontal distance (ft).
- Next, gather the formula from above = ROD = CA / CD.
- Finally, calculate the Average Rate Of Descent.
- 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.

change in altitude (ft) = 3000

change in horizontal distance (ft) = 2000
