Hola! First of all, props to the guy/gal(s) who made the Airport parkour map. Had a lot of fun going through it. Well designed both aesthetically and level-wise. Now... I noticed the runway on the ground and my pseudo-OCD kicked in. So, as you can see in the above screenshot, the north end of the runway is named either "89" or "68" both of which do not make any sense. Runways are named after the heading they are facing ... expressed in degrees (divided by 10 and rounded up). Here is a picture for orientation: North would be 36, East 09, South 18 and West 27 in this system. Alright... lets take a look at an actual, real life runway which is facing south. For example, the Frankfurt Aiport: Facing south = named 18. The other side of this specific runway, which is facing north, would be named 36. By now, I hope you get my ... let's call it a concern ... and understand that a runway named 89 (or 68) doesn't make any sense no matter how 'cool' it may sound. Now, for my suggestion... please, someone fly over there and change the numbers on that poor runway. The north side (from the screenshot) should have a 18 (facing South) on it and the south side a 36 (facing North). Thank you very much! My totally reasonable, not imaginary OCD (/s) will be very pleased with this change. EDIT: Oh... a source for the faithless Runway - Wikipedia (Scroll down to naming) Or just... look at some airports.
