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.

So if you're on runway 9, then you're heading east (90 degrees on a compass).

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 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.

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 ...

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.

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 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.

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.

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°

As runways can be used in two directions, which are 180° apart, they have two numbers that indicate both, with a difference that is always 18. That's why runway 02 is also runway 20 in the opposite direction, and runway 07 is also runway 25.
