Another interesting fact is that there is a difference between American terminology and European terminology. A runway with a magnetic track of, say, 040 would be called ‘Runway Four’ in the US but ‘Runway zero four’ in Europe.

In the US we don’t add the “zero” before single digit runway numbers because it’s not painted with one on the runway nor cataloged as such in the charts. I think Canada might paint on the Zero but still refer to it as a single digit runway. …or perhaps they do that out of courtesy for visitors from the south. 🙂
