What does runway 12 30 mean?

Runways have two ends. Each end is considered a different runway, even though it is the same actual runway surface. If the compass heading of a runway is 122° you would round it down to 120 and drop the last digit, leaving you with 12. Thus it is called Runway 12/30.

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.

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 ...

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.

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.

Is There a Runway 0? You shouldn't find any runway numbered either “0” or “00”. Any runway which points to magnetic north will normally be given the designator “36” (as in 360 degrees). This will also correspond with the headings read out by both ATC and the pilot.

For reference, London Heathrow's two runways are 12,802 and 12,001 feet and both regularly welcome the likes of the Airbus A380 and Boeing 777. London Gatwick has a 10,879-foot runway while Manchester's is 10,000 feet.

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.

Single Physical Runways North-oriented runways are designated 36 (not 00). In simple words, the runway designator represents the heading used for taking off or landing at the runway. If the runway is used in both directions, then each of them receives its own designator.

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.

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.

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.

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!

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.
