Introduction As you sit aboard an airplane, gazing out the window, you might notice the intricate markings on the runway as you prepare for takeoff. Ever wondered what those numbers and letters signify? Whether you're a seasoned pilot or an intrigued passenger, understanding runway designations and airport codes can demystify the world of aviation. This article delves deep into the significance of these markings, revealing the logic and methodology behind them. Understanding Runway Numbers When you spot numbers at the beginning of a runway, know that they represent the runway's magnetic heading, rounded off in multiples of ten degrees. For instance, a runway marked as "18" signifies a magnetic heading of 180 degrees. It's crucial to grasp that these numbers aren't random; they directly relate to the magnetic compass directions. Why Magnetic Heading Matters You might wonder, why are magnetic headings significant? The Earth's geographic North Pole and its ma...
