🧠 Decode any runway

Runway numbers are compass headings divided by ten: 09 points east (90°), 27 points west (270°). One strip of tarmac, two names — always 18 apart. Parallel runways add L, C and R for left, centre and right. And Frankfurt's famous Runway 18 has only one name, because planes are only ever allowed to depart it heading south. Now you can read any airport chart in the world.
