Zwanenburg Runway, Polderbaan Runway and Aalsmeer Runway are located next to each other, at exactly the same degrees: To make it clear to pilots which runway to use, we have added a letter to these numbers. L for left, C for Centre and R for right. This way, everyone knows which runway to use for take-off and landing.
Taxiways The path to and from a runway is called a taxiway. Taxiways have names too. At Schiphol, we have given our taxiways combinations of one letter and one number. These signs are yellow and black. Because planes are not particularly flexible due to their size, length and weight, lines have also been painted on the asphalt to assist pilots while taxiing and to help them take corners for example.
White lines are used for this purpose on runways, and yellow lines on the taxiways. During airport operations, runway number designations are pronounced individually. This level of enunciation ensures clear communication and enhances safety.

By Dave Dargie An airfield design expert explains runway markings—and why the compass is important.

First, a few factoids before I explain: Every public use and military airfield on the face of the earth has or should have runway designations permanently painted at each runway end. Such magnetic shifts are more frequent in airports at high latitudes that are closer to the poles. In , the Fairbanks International Airport in Alaska renamed runway 1LR to runway 2LR when there was enough shift in the magnetic north to mandate a change.
The interval of change at this airport is roughly every 24 years. In the case of busy and large airports, especially an international airport, there can be more than one parallel runway to maintain an orderly flow of air traffic. With multiple airport runways, runway designation can take the form of a combination of numbers and letters. Airports with two parallel runways going in the same direction are designated as the left or right runway with an L or R. For example, Runway 18 will be called 18L or 18R.
This direction is relative to the direction the aircraft is facing. Some airports also have three parallel runways and in this case, the designation of C will be assigned to the runway in the center. For example Runway 18L, 18C, and 18R. In rare instances where four runways run in parallel, there is no fourth designation and instead, one number is shifted by 10 degrees.
Such runways are separated by several hundred feet. It is important to note the direction in which an aircraft will take off or land on a particular runway. Departing from Runway 18L means that you are heading South. However, on the same runway, if the aircraft was taking off in the opposite direction, it means that it was heading North at heading degrees.
Heading degrees is reciprocal or opposite of heading degrees. This is why runways have two numbers at each end, where direction changes accordingly.
Therefore, the complete runway number would be 18LR for one end and 18RL for the other end. Atlanta Airport is an exceptionally busy airport with five active runways.
There is a runway 26L and 26R, a runway 27L and 27R, and a runway Each of these runways has the same heading of Therefore, it is vital for the pilots, air traffic control , and other aviation personnel to be familiar and clear with the airport layout and regulations, especially the critical and busy areas including the runways and the taxiways.
Without these rules and regulations, there would likely be chaos in the air and on the ground. Due to this, uniformity and similarity are adopted by all the airports worldwide to leave little room for confusion, misunderstandings, or mistakes, especially at critical times.
