Precision Approach Path Indicator PAPI lights are a type of visual glide slope indicator used in aviation. They consist of two, three, or four lights arranged in a line from top to bottom. The lights are usually red, but can also be white or green.
In this article, we will take a look at 6 facts you need to know about PAPI lights.
1. They reduce the risk of runway incursions:
These lights are an important tool for both commercial and military pilots. They help pilots maintain an accurate approach path during landing, which reduces the risk of runway incursions. Runway incursions are defined as any unauthorized vehicle or person on an active runway or taxiway. They have been responsible for over 200 accidents per year in recent years, which is why such lights can be a lifesaver when it comes to preventing runway incursions.
2. They provide a visual glide slope:
These lights are used during instrument approaches to aid pilots in maintaining the correct angle of descent toward the runway during landing. They provide pilots with an indication of how far above or below the horizon they are flying. You can easily buy these lights at affordable rates online at different stores that offer taxiway lights for sale.
3. They are visible from miles away:
These lights are designed to be visible from miles away. The intensity of each light is adjusted to ensure that pilots can see them from a safe distance when they’re approaching an airport or runway. This helps prevent accidents caused by pilot errors during landing procedures.
4. They are used by both commercial and military pilots:
The Precision Approach Path Indicator (PAPI) system is used worldwide by both commercial and military aircraft. These lights are an important tool for pilots during approach and landing. The lights indicate whether the aircraft is on the correct glide path, allowing pilots to land safely.
5. They consist of a series of straight lines that form a triangle.
These lights consist of two, three, or four lines that form a triangle from top to bottom. Each line has its own colour, but red is the most common colour for all three types of PAPI lights. The red colour makes it easier for pilots to see in low light conditions or dark nights.
PAPI lights are a vital tool for pilots during approach and landing. So, it’s important to know how these lights work if you want to keep your aircraft safe over the runway.
