Estimate a recommended intercept angle and heading for VOR and localizer course intercepts. This free aviation calculator helps instrument pilots and students practice IFR tracking and intercept planning.
Enter your current heading, desired course, and navigation type to estimate a recommended intercept angle and intercept heading.
This is a training aid that recommends a practical intercept angle. Actual intercept technique depends on wind, course sensitivity, aircraft speed, and instructor or procedural guidance.
An intercept angle calculator helps pilots choose a practical heading to join a desired course, such as a VOR radial or localizer final approach course.
In instrument flying, choosing the right intercept angle helps avoid overshooting, improves course capture, and makes tracking smoother and more stable.
Many pilots use a moderate intercept angle, often up to around 45 degrees depending on speed, wind, and distance from course.
Localizer intercept angles are commonly smaller, often around 20 to 30 degrees, to avoid overshooting the more sensitive signal.
Wind can push the aircraft off course during the intercept, so the actual intercept heading used in flight may need to include wind correction.
