What is an important step when preparing for a cross-country flight regarding wind correction?

When preparing for a cross-country flight, an important step is determining the wind direction. This allows pilots to make necessary adjustments to their flight path to ensure they maintain their intended course. Wind can significantly influence the aircraft's trajectory, and understanding its source is crucial for calculating the wind correction angle.

By determining the wind direction, pilots can decide if they need to implement a left or right wind correction angle in their navigation calculations. This step is vital for accurate flight planning and for reducing the chances of drifting off course due to wind effects. Failing to account for wind can lead to significant navigation errors, which could compromise the safety and efficiency of the flight.

In contrast, adding a left wind correction angle or subtracting a right wind correction angle are actions taken after determining the wind direction; these choices are adjustments made based on the initial assessment of the wind, which is why they are not the fundamental step needed in preparation. Ignoring the wind altogether is also not feasible, as it would overlook a major environmental factor affecting the flight.
