The big runway numbers and their meaning

All runways are numbered between 01 and 36, which indicate compass bearing in which runways are oriented. For instance, if you are on runway 27, it means that you are actually heading west (270 degrees on a compass.

At big and busy airports such as London Heathrow (LHR), there may be two runways 27 with different letters such as 27L and 27R. In this case, the two letters stand for R-right and L-left, so the air traffic controller will tell pilots where to land at 27L (two-seven-left), or 27R (two-seven-right).
