Hey guys, this is Collin with Easy Aviation English and I've got a quick lesson on runway
markings.
The "Threshold" shows the beginning of the runway where an airplane can land.
The "Centerline" helps the pilot maintain the airplane right in the middle of the runway.
The "Aiming point" acts as a reference to touch down in the "Touchdown zone".
A runway may also have a "Displaced threshold".
A displaced threshold is an extended area for an airplane to takeoff but not land.
A "Blast pad" is an area to protect objects and people from jet wash.
But what is "Jet wash"?
Jet wash is fast moving air created by a jet engine.
Another word to remember since we're talking about runways is "Wind sock".
A wind sock measures a winds direction and velocity.
