Magnetic variation is crucial in navigation because it accounts for the difference between true north (geographic north) and magnetic north (the direction a magnetic compass points). This difference can vary depending on where you are on Earth, and it changes over time due to shifts in the Earth's magnetic field. Accurate navigation requires the pilot to convert headings from magnetic to true or vice versa. Without taking magnetic variation into account, there can be significant errors in navigation, potentially leading to incorrect positioning and flight paths. Therefore, understanding and applying magnetic variation ensures that navigators maintain precision in their courses and safely reach their destinations.
