What do the numbers 9 and 27 on a runway indicate?


What do the numbers 9 and 27 on a runway indicate? 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.


What does 06 24 mean on a runway?

Runways will be numbered based on their position so 06/24 means one end of our runway is 60 degrees, the opposite end is 240 degrees – so 180 degrees, also known as a straight line!


What does runway 17 35 mean?

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.


What does runway 15 33 mean?

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.


What does runway 18 36 mean?

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 ...


What is runway 07?

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.


What is the runway number 22?

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.


What does runway 37 mean?

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.


Why are runways always 27?

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.


What does runway 27 mean?

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.


What does 9 and 27 mean on runway?

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.


What is the largest airport in the US?

Dallas Fort Worth (DFW) is one of the world's largest airports, ranking second globally in passenger numbers and third in aircraft movements. DFW was built between 1967 and 1973 and became operational on January 13, 1974, with American Airlines' first commercial flight.


Which airport has the most runways?

The airfield is managed by three FAA air traffic control towers. O'Hare has a voluntary nighttime (22:00–07:00) noise abatement program. Currently, O'Hare has the most runways of any civilian airport in the world, totaling eight.
