Wind Correction Angle (WCA)
How is Wind Correction Calculated?
The calculator determines the wind correction angle (WCA), required heading, ground speed, and wind components using trigonometric formulas based on your input.
WCA: arcsin((Wind Speed × sin(Wind Dir - Course)) / TAS)
Ground Speed: TAS × cos(WCA) + Wind Speed × cos(Wind Dir - Course)
All angles in degrees. Results are rounded to nearest tenth.
The Wind Correction Calculator is an essential online tool for pilots, navigators, and aviation enthusiasts who want to accurately determine how wind affects their flight path. In aviation, wind speed and direction can significantly alter an aircraft’s heading and ground speed. This calculator instantly computes your Wind Correction Angle (WCA), heading to steer, ground speed, and crosswind/headwind components — ensuring your navigation remains precise and safe.
Whether you’re a seasoned pilot planning a cross-country route or a student learning navigation, this tool simplifies complex trigonometric calculations into clear, actionable results.
How to Use the Wind Correction Calculator
Follow these steps to get accurate results:
- Enter True Airspeed (TAS)
- Input your aircraft’s true airspeed in knots. This is the speed relative to the surrounding air.
- Enter Course (degrees)
- The intended flight path you want to follow, in degrees from 0 to 360.
- Enter Wind Direction (degrees)
- The direction from which the wind is coming, in degrees.
- Enter Wind Speed (knots)
- How fast the wind is blowing.
- Click “Calculate”
- The calculator will simulate a brief progress bar before displaying your results.
- View Results
- See your Wind Correction Angle, Heading to Steer, Ground Speed, Crosswind Component, and Headwind Component.

Example Calculation
Let’s say you’re flying with these conditions:
- True Airspeed (TAS): 120 knots
- Course: 90° (due east)
- Wind Direction: 45° (northeast wind)
- Wind Speed: 20 knots
After entering these values:
- Wind Correction Angle (WCA): +6.7°
- Heading to Steer: 96.7°
- Ground Speed: 129.0 knots
- Crosswind Component: 14.1 knots
- Headwind Component: 14.1 knots
This means you’ll need to adjust your heading slightly right to maintain your desired course, and your ground speed will be slightly faster than TAS due to partial tailwind.

Pro Tips for Best Results
- Always use True Airspeed (TAS), not Indicated Airspeed.
- Enter wind direction as the direction it’s coming from, not going to.
- Double-check that your course and wind direction are in degrees, 0–360.
- Positive WCA means turn right; negative WCA means turn left.
FAQ – Wind Correction Calculator (20 Questions & Answers)
1. What is a Wind Correction Angle (WCA)?
The angle you adjust from your intended course to counteract wind drift.
2. Why is WCA important in aviation?
It ensures you maintain your planned track over the ground despite wind.
3. What is True Airspeed (TAS)?
Your aircraft’s speed relative to the air around it, corrected for altitude and temperature.
4. How do I measure wind direction?
From the direction the wind originates, expressed in degrees.
5. Can I use this for drones?
Yes, it’s also useful for UAV and drone navigation.
6. Does the tool work for boats?
Yes, by treating current and wind similarly in the calculations.
7. What does “Heading to Steer” mean?
The actual compass heading you need to fly to stay on course.
8. How is Ground Speed different from TAS?
Ground speed is TAS adjusted for wind; it’s your speed over the ground.
9. What is a crosswind component?
The sideways force of the wind relative to your course.
10. What is a headwind component?
The wind blowing directly against or with your course, affecting speed.
11. How accurate is this calculator?
Extremely accurate when inputs are correct, using standard aviation formulas.
12. Do I need GPS for this tool?
No, just TAS, course, wind direction, and wind speed.
13. Is this suitable for student pilots?
Absolutely — it’s a great learning aid.
14. What happens if I enter wrong values?
The results will be incorrect, so always double-check inputs.
15. Can I use metric units?
Currently, it’s in knots and degrees; convert before inputting.
16. Does it work for helicopters?
Yes, any aircraft type can use these calculations.
17. Can it account for changing wind mid-flight?
No, you’d need to re-calculate with updated wind data.
18. Is there a mobile-friendly version?
Yes, the tool is designed to work on mobile devices.
19. How long does the calculation take?
About 3 seconds, including the progress animation.
20. Can I share my results with others?
Yes, via the built-in share button or copy function.
This Wind Correction Calculator simplifies an essential part of navigation, saving pilots time and improving accuracy. Whether you’re flying across a state or across the ocean, knowing your wind correction angle ensures you reach your destination exactly as planned.
