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.

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.

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.

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.

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.

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 reason that Denver's runways are so long is down to the altitude at which the airport is situated. Colorado's capital is known as the 'Mile High City,' and, correspondingly, its airport finds itself situated 1,656 m / 5,434 ft above sea level.

Why aren t runways wider? A wider-than-usual runway can create an illusion that the aircraft is lower than it actually is, leading to a higher approach and greater slope. On a very wide runway you might flare too early and even stall the airplane a few meters above ground.

MORE DETAILS

All runways are numbered based on the magnetic azimuth (compass bearing) in which a runway is oriented. There are 360 degrees on a compass rose.
