In which runway configuration is the 9L-27R designation found?

The designation "9L-27R" refers specifically to a runway identification system used at airports. In this system, the numbers correspond to the runway's compass bearing rounded to the nearest 10 degrees. "9" indicates a flight direction of approximately 90 degrees (or east), while "27" indicates a direction of approximately 270 degrees (or west). The letters 'L' and 'R' denote left and right, allowing for dual runways to be identified clearly when they are parallel.

This system is integral to air traffic operations as it allows pilots and air traffic controllers to communicate clearly and efficiently about which runway is in use. Thus, the designation directly relates to runways rather than taxiways or approaches. The other options refer to elements that are not associated with the specific naming and identification of runways.
