The numbers 14 and 22 on a runway indicate what about its orientation?

The correct interpretation of the numbers 14 and 22 on a runway refers to its orientation in relation to magnetic headings. In aviation, runway numbers are derived from their magnetic compass heading, rounded to the nearest 10 degrees.

The number 14 indicates that the runway is oriented towards approximately 140 degrees. To arrive at this number, one takes the magnetic heading of 140 degrees and divides it by 10, which results in the number 14.

Similarly, the number 22 indicates that the runway is oriented towards approximately 220 degrees, following the same process of deriving the number from the magnetic heading.

Thus, when combined, these two runway numbers denote that one end of the runway is aligned at roughly 140° magnetic, while the other end is aligned at approximately 220° magnetic, demonstrating the relative orientation of the runway. Understanding how these numbers connect to actual headings is crucial for navigation and operations within the airspace surrounding an airport.
