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.

1. First, determine the change in altitude (ft).
2. Next, determine the change in horizontal distance (ft).
3. Next, gather the formula from above = ROD = CA / CD.
4. Finally, calculate the Average Rate Of Descent.
5. 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
