So if you're on runway 9, then you're heading east (90 degrees on a compass). Runway 36 means you're moving north, and so on.

Runway 36 is the entire runway, with traffic moving to the north (i.e. facing about 360 degrees, magnetic). Runway 18 is the same north/south strip of pavement, with traffic moving to the south (i.e. facing about 180 degrees). If you're lined up ON runway 36, you're at the south end of it, facing north.
A runway can normally be used in both directions, and is named for each direction separately: e.g., runway 15 in one direction is runway 33 when used in the other. For clarity in radio communications, each digit in the runway name is pronounced individually. Airports with parallel runways.
Plainly put, airport runways are numbered according to compass bearings. This means runway numbers are based on the compass with 360 representing north, 90 representing east, 180 representing south, and 270 representing west. Runways are numbered between 01 and 36. Aerial view of a numbered airport runway.
In addition, runway numbers are connected to the direction a plane is traveling—so while on a handheld compass, south corresponds to 180 degrees, or 18 in runway terms, if a plane is on runway 18–36, then it's heading north, according to the designation on a compass with the runway overlay (see image below, courtesy of ...
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.
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.
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.
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.
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.
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. So runway 24 is 240 degrees from magnetic north, and runway 36 runs right along it.
ICAO SARPs relating to runways are determined according to runway length using the standard Runway Code categories. Code 1 runways are less than 800 metres long, Code 2 runways are 800-1199 metres long, Code 3 runways are 1200-1799 metres long and Code 4 runways are 1800 metres or more in length.
Generally, a typical runway length for a fully loaded Boeing 747-400, one of the most common variants, is around 10,000 to 12,000 feet (3,048 to 3,658 meters) for takeoff.
All runways are numbered. The number used corresponds to the magnetic direction of that runway when landing or taking off on it. The runway number is abbreviated and missing the last digit. As an example. If you are landing or taking off on runway 20, it is actually 200°
So what do these numbers on runways mean? The numbers on the runway, officially known as designators, indicate the runway heading, always in magnetic degrees and rounded to the nearest ten. So, if the magnetic bearing is 73º, the runway will be designated with the numbers 07.
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.
