On the sectional look for the dashed magenta lines with a number nearby. Well, not exactly. Low boat speed and high winds also increase leeway, as does excessive heeling. True heading is Probabilities always range between 0 and 1. This is simply the angular difference between the geographic north pole (at the top of the globe) and where your compass points (a point at the top of Northern Canada). If you're expecting current, you'd put a way point at the edge of the expected current, then do the CTS calculation to the other edge of the current. These errors are referred to as deviation. 3. north and magnetic north are two things that arent thought about with everyday Leeway is difficult to estimate, and even harder to plot proactively on a chart since you don't know the wind direction you'll be sailing in until you're on the water. XTE mode drives the boat to stay within a certain distance of the plotted course line - it keeps the cross track error within set parameters. Want to know how to do that in an aircraft? This is the CTS (Course to Steer). Now we know the maximum drift, it is easy to apply a correction to true course vs. true heading. which helps us get from point A to point B most directly. (Scimitar-Shaped). tc var = cc + dev = mc. The initial values will clear on each field as you click on it to enter information. True heading corrects for wind.
