Enter the wind speed (knots) and the ground speed (miles/min) into the Calculator. The calculator will evaluate the Drift Angle.

## Drift Angle Formula

MDA = WS / GS

Variables:

- MDA is the Drift Angle (degrees)
- WS is the wind speed (knots)
- GS is the ground speed (miles/min)

To calculate Drift Angle, divide the wind speed in knots by the ground speed in miles per minute. This gives an approximate value for the drift angle.

## How to Calculate Drift Angle?

The following steps outline how to calculate the Drift Angle.

- First, determine the wind speed (knots).
- Next, determine the ground speed (miles/min).
- Next, gather the formula from above = MDA = WS / GS.
- Finally, calculate the Drift Angle.
- 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.

wind speed (knots) = 30

ground speed (miles/min) = 20
