Airport markings, explained

I recently posted (on Facebook) two more videos that I previously authored for the Youth Aviation Adventure's modular curriculum designed for future aviators.

The videos cover Airport Marking Aids and Signs in two parts, providing an overview of various pavement marking aids and signs found in the airport environment such as runways, taxiways, and holding areas.

As always, I enjoyed making the videos and learned a great deal in the process as well. For example, can you answer the following question?

If your answer is "I don't know", then go ahead and watch the videos below (answer at the bottom of the page).

For more information and details, you can review the "Aeronautical Lighting and Other Airport Visual Aids: Airport Marking Aids and Signs" section of the Federal Aviation Administration Aeronautical Information Manual.
