End of dialog window. Painted very bold red/white chequerboard pattern so they stand out in low visibility.

Some countries also paint radio transmission towers near airports in the red/white pattern.

What do the red and white lights mean on runway?

There are three color codes of a VASI: Source. When both the VASI-bars are red, as in your picture, the plane is too low and needs to pitch up. Red and white means on glidepath and two whites mean too high and the pilot needs to descend faster.

What are the different airfield signages?

There are six types of signs installed on airfields: mandatory instruction signs, location signs, direction signs, destination signs, information signs, and runway distance remaining signs.

What are the different types of airport runways?

The three classifications of runways are Visual Runways, Nonprecision Instrument Runways, and Precision Instrument Runways.

How does a VASI work?

The individual lightboxes that make a VASI work are made of two light bulbs with a solid divider between them. The red light is below the white light. The box itself is mounted to the ground at the angle at which you want the light to change. So while the VASI sounds and looks pretty complicated, it’s very simple.

What’s the difference between PAPI and VASI?

The only functional differences between the VASI and PAPI is that the VASI has the red over the white, the PAPI the white actually goes to the right of the red, and the PAPI offers higher precision (or more glideslopes depending how you look at it a larger airliner with a high cockpit may elect to fly a slightly higher …

What does a VASI look like?

A VASI is a set of two or three bars, each on top of the other. The lights that make up the bars appear red or white from the pilot’s point of view, depending on the aircraft’s position. Another standard system found at airports has four lights set side-by-side.

What is a Pvasi?

Pulsating visual approach slope indicators (PVASI, aka PLASI) normally consist of a single light unit projecting a two-color visual approach path into the final approach area of the runway upon which the indicator is installed. The on-glidepath indication is a steady white light.
