Air draft

Air draft refers to the height of something that is moving through the air. It's kind of like how some things are too tall to fit through doorways or under bridges.

If you've ever seen a big boat or ship, you might notice that they have really tall things sticking up, like the mast or the smokestack. These things can't be too tall, or else they will hit things like bridges or power lines that go over the water.

So, when we talk about air draft, we are talking about the maximum height that something can be and still safely pass under things like bridges without bumping into them.

Usually, people measure air draft by starting at the tallest point of the object, like the top of the mast on a boat, and then measuring downwards to where the object meets the water. This helps people know if something can fit safely under bridges or other low-hanging obstacles.

So air draft is all about making sure things can move around safely without crashing into anything too low.
