What does it mean if a runway is designated 32l or 32c?
Parallel operationsThere are plenty of airports that have parallel runways, and therefore will have an additional identifier, such as L for left or R for right—or less commonly C for center.

The letters, differentiate between left (L), right (R), or center (C) parallel runways, as applicable: For two parallel runways “L” “R.”For three parallel runways “L” “C” “R.”
Runways are named by a number between 01 and 36, which is generally the magnetic azimuth of the runway's heading in decadegrees. This heading differs from true north by the local magnetic declination.
A: The runway number is the approximate magnetic heading. As an example, runway 35 is pointing approximately 350 degrees magnetic. The opposite end of the runway is 17 or approximately 170 degrees magnetic.
For example, Runway 9-27 is oriented east-west. You might be thinking that the numbers on this diagram are backwards. On a handheld compass, south is 180 degrees (so 18 in runway terms) and west is 270 (27). But the “W” is numbered 9 because the runway number is connected to the direction the plane is traveling.
Advertisement. The first digit in the number uses the actual bearing and the second digit is rounded off to the nearest degrees. The last number in the degree is always dropped. Advertisement. So if a runway number is 27, it means that the direction of the runway is 270-degrees from North.
Runway 22 means that the airplane's magnetic heading on this runway will be about 220 degrees when taking off or landing. The actual heading may be 224 degrees, but it is called 22. If the actual heading was 226 degrees then the runway would be 23, or considered 230 degrees.
Runway 13-31 is a primary runway at ACY and is 10,000 feet long by 150 feet wide, including 25 feet of paved shoulder on both sides, which features ILS approaches at each end, precision instrument pavement markings, and High-Intensity Runway Lighting (HIRL) and a Medium-Intensity Approach Lighting System with Runway ...
Runway numbers are actually a reference to the closest magnetic heading of the runway. The runway heading is rounded to the nearest 10 degrees, and the zero is removed. This number is then assigned to the runway. Further differentiation can be achieved with letters on parallel runways.
