Large Tarmac letters

Have you ever wondered what those large numbers on the airport tarmac is all about? Street signs perhaps? Well, that’s close. Today’s post is a short one. Because we feel you need to click on this link and watch the short youtube video.

It’s a marvel to learn a few things about geography.

So after reading the article you will know what the numbers mean. For those who did not click on the above link (tsk tsk), they are representations of cardinal directions between 0° to 360°. But it is truncated. Thus if an aircraft’s compass is not working, the pilot can still tell in which direction his/her plane is approaching the airport.

Now you see why they paint the numbers so large… the better that they can see you be seen so said the big bad wolf article… And hopefully now it makes sense to you why there are letters on the tarmac.

But we are not only sharing with you what we’ve learned about these markings and numbers. Recall our post on the language of pilots? Flying is still a complex business, and we are not referring to the business of running an airline. The control of a complicated aircraft with millions of moving parts all coordinated by software is the deal we are talking about. You will come to read our take on the advent of pilotless aircraft in a future post.

Think about that for a moment. No pilot. If that happens, will we still need the large letters on the tarmac?
