What is the Coriolis effect's impact on navigation?

The Coriolis effect is a result of the Earth's rotation, causing moving objects, including aircraft, to be deflected from their intended path. This phenomenon is especially significant in navigation because it affects course calculations over long distances. As an aircraft travels, its trajectory will appear to curve relative to the Earth's surface due to its rotation.

For pilots and navigators, understanding and accounting for this deflection is crucial for maintaining accurate course alignment. Without considering the Coriolis effect, a pilot could miscalculate their flight path, leading to a substantial error in navigation, particularly in flight planning for long hauls. This is why the influence of the Coriolis effect on course calculations is an essential aspect of navigation.

The other options do not accurately reflect the role of the Coriolis effect in navigation. It does not merely accelerate aircraft, nor is it solely relevant during takeoff—its influence is pervasive throughout a flight. Additionally, it certainly has a significant impact on navigation rather than having no effect.
