How do pilots identify the runway strip?

Runway Designators. Runway numbers and letters are determined from the approach direction. The runway number is the whole number nearest one‐tenth the magnetic azimuth of the centerline of the runway, measured clockwise from the magnetic north. For three parallel runways “L” “C” “R.”

How do pilots know which runway to takeoff from?

Primarily, the “ILS,” as it is commonly known, consists of two radio beams emitted from transmitters right next to the runway. All pilots have to do is follow the beams down to 200 feet above the ground, at which point they must be able to see the runway and its approach lights.

How far apart are runway stripes?

Each runway centerline stripe is 120 feet long and 36 inches wide. The gaps between each stripe are 80 feet. This is one of the best aids in determining your landing point, or how far you’ve floated down the runway.

How do airplanes know where to land on the runway?

The first signal is the localizer, radiating from antennae which sit at the end of the runway. This shows the pilots where the aircraft is in relation to the centerline. The second signal comes from antennae to the side of the runway, around 1,000 feet in from the threshold abeam the touchdown zone.

Do pilots stop before the hold line at uncontrolled airports?

At uncontrolled airports, pilots are expected to stop before the hold line until the runway is clear to cross, or to turn onto, the runway.

What are the criteria for making an approach to the runway?

This criteria varies from approach to approach, runway to runway and aircraft to aircraft. There are two elements to the approach: the visibility and the Minimum Descent Altitude (MDA)/ Decision Altitude (DA).

What is a centerline on an airport runway?

Pilots must ensure they understand precisely which runway they are cleared to land on; at busy airports arriving aircraft may be flying parallel to each other, landing at nearly the same time on parallel runways. The runway centerline is simply a white stripe down the middle of the runway.
