The Importance of Runway Guard Lights

Runway guard lights are a critical part of airport infrastructure that play a vital role in ensuring the safety and efficiency of aircraft operations. These lights are designed to mark the boundaries of the runway holding area, also known as the runway hold position, which is where aircraft wait before entering a runway for takeoff or after landing. In this article, we will explore the key aspects of runway guard lights and their locations, providing verifiable data and interesting information.

The Role of Runway Guard Lights

Runway guard lights serve as visual aids for pilots, air traffic controllers, and ground personnel. They help to prevent runway incursions, which are unauthorized aircraft, vehicles, or pedestrians entering the protected area. By clearly indicating the hold position, these lights ensure that aircraft and other vehicles do not unintentionally cross into an active runway, minimizing the risk of collisions and accidents. Let’s take a closer look at the specific locations where runway guard lights are found:

Runway Guard Lights at the Touchdown Zone

Located at the end of the runway, the touchdown zone is where landing aircraft make contact with the ground surface. Runway guard lights are positioned here to provide pilots with a clear visual reference as they slow down, ensuring they do not overshoot the runway’s protected area.

Runway Guard Lights on the Taxiway

Connecting the runway to the airport terminal and other facilities, the taxiway is used by aircraft for ground movement. Runway guard lights are installed at the entry points where the taxiway intersects the runway, reminding pilots to hold their position until authorized to proceed.

Runway Guard Lights at Runway Intersections

Some airports have multiple runways that intersect. At these intersections, runway guard lights are placed to clearly mark the hold position for aircraft on each runway. This ensures that any aircraft approaching from different directions are aware of the boundaries and can safely cross without interference.

Runway Guard Lights at Holding Points

Specific areas along a taxiway or at the runway’s edge are designated as holding points. Runway guard lights are installed at these points to indicate where aircraft should wait until given instructions to proceed. This prevents congestion on the taxiway and ensures orderly movement of aircraft.

Runway Guard Lights on Instrument Landing Systems

Instrument Landing Systems (ILS) provide precise guidance for aircraft during approach and landing. Runway guard lights are often integrated into the ILS infrastructure, helping pilots align their aircraft with the runway and maintain the correct position during low visibility conditions.

Runway Guard Lights at Displaced Thresholds

A displaced threshold occurs when a portion of the runway is not usable for landing aircraft due to obstructions or other factors. Runway guard lights are installed at these thresholds to indicate the actual start of the usable runway, ensuring pilots have the correct reference point for their landing approach.

Runway Guard Lights at Holding Bays

Holding bays are designated areas where aircraft can wait before they are cleared to enter the runway. Runway guard lights are often positioned at the boundaries of these bays, allowing pilots to easily identify the hold position and ensure that they do not encroach into active runway areas.

Runway Guard Lights on Precision Approach Path Indicators

Precision Approach Path Indicators (PAPI) provide pilots with vertical guidance during approach and landing. Runway guard lights are sometimes integrated into the PAPI system, complementing the visual cues provided by the horizontal PAPI lights and helping aircraft maintain the correct glide path.

Runway Guard Lights at Gate Hold Positions

Prior to entering the taxiway and runway areas, aircraft must often wait at gate hold positions. Runway guard lights are installed at these positions to clearly mark the boundary, ensuring that aircraft are held back until it is safe and authorized to proceed.


Runway guard lights are an essential component of airport safety systems, creating clear and visible boundaries for aircraft operations. By highlighting the different locations where these lights are installed, pilots, air traffic controllers, and ground personnel can effectively manage aircraft movements and prevent runway incursions.
