TIL US airport runway numbers are named for the direction in which they point:
- Take the runway number, multiply by 10
- That angle is the direction of the runway
So runway 9 points due east (90°) and runway 27 due west (270°).
The same physical runway will change numbers if they switch the direction of traffic.
