I'm so confused how airport numbering works. If an airport has a single runway oriented 063 degrees and 243 degrees M. What would be the runway designator?
When a runway is at Magnetic Heading 063, it is rounded to the nearest 10° , which is 60°, so its designation is Runway 06
When a runway is at Magnetic Heading 243, it is rounded to the nearest 10° , which is 240°, so its designation is Runway 24
Since you can take off or land on a runway from either end, a single strip of asphalt will typically have two numbers, one for each end. These two numbers will always be 180° apart, or their designations will be 18 different.
So Runway 06/24 refers to a single runway, that you can use from either end.
