The runway itself is also called the tarmac. The name comes from a specific tar-based paving material that's also commonly used on roads. Originally, the word was trademarked as shorthand for tarmacadam, tar mixed with crushed rock.

In general, tarmac is oftentimes used to refer to different areas of an airport where aircraft roam, but the truth is that airports have no area or section officially called tarmac. The parts that are commonly referred to as tarmac include: The runway, which is the way used for takeoff and landing.
The airport apron, apron, flight line, ramp, or tarmac is the area of an airport where aircraft are parked, unloaded or loaded, refueled, boarded, or maintained. Although the use of the apron is covered by regulations, such as lighting on vehicles, it is typically more accessible to users than the runway or taxiway.
Runway numbers are determined by rounding the compass bearing of one runway end to the nearest 10 degrees and truncating the last digit, meaning runways are numbered from 1 to 36—as per the diagram below. The opposite end of the runway always differs by 180 degrees, so it's numbered 18 higher or lower.
The ”L” and ”R” designate the relative position (left or right) of each runway respectively when approaching/facing its direction. A small number of airports have three parallel runways—the runway in the middle gets a “C” for center. During airport operations, runway number designations are pronounced individually.
Adding tar to macadam makes the surface waterproof as well. Since airplanes must take off and land in all sorts of weather, airport runways are often paved with tarmacadam, as are public roads and highways.
However, it's not the official designation. The use of ramp has its roots in airports that serve both seaplanes and traditional airplanes as a literal ramp from the water to the airfield. Outside the U.S. and Canada, it's a term that virtually no one uses.
As Atlas Obscura explains, the numbers that runways have aren't arbitrary. A runway always has a number between 1 and 36, and that number isn't just the runway's nickname, but also indicates how many degrees away that runway is from magnetic north, rounded to the tens.
Shigatse Peace Airport, China (runway length: 5,000m)Shigatse Peace Airport (RKZ), a dual-use military and civilian airport in Shigatse, Tibet hosts the longest runway in the world. The new runway (09/27) stretches 5,000m (16,404 ft) long with a 60-meter asphalt overrun at each end.
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.”
There is a purpose in using call signs. In an article written by Kate Lang from the Department of Defense News, she explains, “These pilot nicknames can quickly identify an aircraft or individual, and they also help to confuse the enemy, who might be listening in on your communications.”
1 Answer. Most small airports have places for transient aircraft parking. Sometimes they are paved and have tiedown spots, other times is might be a grass field. Prepared pilots may bring their own tie down anchors if windy conditions are anticipated.
Some other runways appear to go up and down at different points. Answer: No, runways are not flat. They are crowned to help drain water off the sides during rain, and often one end of a runway is higher or lower than the other. When preparing takeoff performance calculations, pilots include the slope of the runway.
The most used is the Instrument Landing System or ILS. The ILS consists of two radio beams which project up from the area around the runway up into the approach path. These signals are then picked up in the aircraft by the ILS receiver which displays them on the screens in the flight deck.
Since most runways are oriented to take advantage of prevailing winds to assist in takeoffs and landings, they can be used either direction. This is why most runways have two numbers. The second number differs by 18 or 180 degrees.
