You see this little sign all over airport runways. What's it mean?
I've seen 25R-7L (or vice versa) here in USA as well. I assume it's something to do with Left and Right and a distance but can anyone explain?
It is the number of the runway and has the format n[L|R|C|]
Where n is the [approximate] number of degrees from 0 Magnetic that the runway point; each runway has, therefore 2 numbers
L indicates that it is the left runway
C indicates that it is the Centre runway
R indicates that it is the Right runway
e.g. 25R would be the right of 2 or more runways aimed at 250 degrees; approached from the other end would be 7L since it will be aimed at 250-180 = 70 degrees and be the left of 2 or more runways
