# I'm so confused how airport numbering works [duplicate]

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?

• 06/24... what is the confusing part? Rounding? – Ron Beyer Feb 17 '17 at 3:52
• I know that runways are determined by their heading so runway 243 is like South West and 063 would be North East. – IceCold Feb 17 '17 at 4:04
• Right, so I'm wondering what the confusing part is, how the numbers are rounded? Runways aren't identified by cardinal points (NE, NW, SW, etc). – Ron Beyer Feb 17 '17 at 4:08
• I'm confused myself because its one of the questions on this textbook that im studying and it says the following. "An Airport has a single runway oriented 063 degrees/243 degrees M. What is the appropriate runway designato?" So what i dont get is how runways are designated or i guess identified. – IceCold Feb 17 '17 at 4:12
• 06/24 like I said, runways are designated by the first two digits of the 3-digit magnetic heading. 025 = 02, 122 = 12, etc. Take a look at the duplicate question I marked. – Ron Beyer Feb 17 '17 at 4:14
