How is the center runway designated when there are three parallel runways?

In the context of runway designation, the center runway among three parallel runways is identified by the letter corresponding to its position. The runways are numbered based on their magnetic heading rounded to the nearest 10 degrees, and when there are three parallel runways, the middle runway is designated with a letter.

The standard designation is as follows: the leftmost runway is usually given the letter 'L' for "Left," the rightmost is designated with 'R' for "Right," and the center runway is marked with 'C' for "Center." This helps pilots and air traffic controllers clearly communicate which runway is being referred to, minimizing potential confusion, especially during busy operations.

In this scenario, the center runway is therefore designated with 'C', distinguishing it effectively from the left and right parallel runways. This designation system is crucial for ensuring safety and efficient communication in airport operations.
