This can be particularly important during night flights or in poorly lit airport sections.

• Emergency Evacuation

  Threshold lighting is crucial in emergency situations, such as fire incidents or power failures. It ensures that evacuation routes are well-lit and visible, allowing passengers and staff to exit the premises quickly and safely. The lighting systems can be powered by backup generators or batteries to remain operational during emergencies.

• Illumination

  Threshold lighting provides illumination to enhance visibility for various airport operations, including baggage handling, aircraft parking, and passenger boarding. Adequate lighting is essential for the safe and efficient execution of these tasks, particularly during nighttime operations.

• Accessibility

  Threshold lighting is essential for ensuring accessibility for all passengers, including those with disabilities. Properly lit areas make it easier for individuals with mobility challenges or visual impairments to navigate the airport safely. This may include well-placed lighting in stairways, ramps, and accessible restrooms.

• Air Traffic Management

  Threshold lighting plays a significant role in air traffic management by marking the location of runways, taxiways, and other critical areas. It helps pilots and air traffic controllers navigate these areas safely, particularly during low visibility conditions. Runway threshold lights, for example, indicate the beginning of the runway and guide aircraft during landing and takeoff.

• Branding and Aesthetics

  Threshold lighting can also contribute to the branding and aesthetics of an airport. Well-designed lighting systems can create a welcoming atmosphere for passengers and visitors, leaving a positive impression. This is especially important for international airports that cater to travelers from around the world.

Scenarios of threshold lighting in airport

Threshold lighting is typically used in the following scenarios:

• Runway Edges

  Threshold lighting is placed along the edges of runways to guide aircraft during takeoffs and landings. The lights mark the runway boundaries, helping pilots navigate safely, especially in low-visibility conditions.

• Runway Thresholds

  These lights indicate the beginning of the usable runway for landing aircraft. They help pilots align their approaches and touch down at the appropriate point on the runway.

• Taxiways

  Threshold lighting illuminates taxiways to direct aircraft and ground vehicles after landing or before takeoff. The lights ensure safe movement on the airfield, reducing the risk of collisions.

• Heliports

  Threshold lighting is used in heliports to guide helicopters during landing and takeoff. The lights mark the helipad boundaries and safe landing zones.

• Lighting Systems

  Threshold lighting can be part of advanced lighting systems that include precision approach path indicators (PAPI) and runway visual range (RVR) systems. These components work together to enhance visibility and guide aircraft during various weather conditions.

• Night Operations

  Threshold lighting is essential for airports operating primarily during nighttime hours or in low-light conditions. The lights ensure safe aircraft operations regardless of visibility.

• Adverse Weather Conditions

  These lights are crucial in airports experiencing fog, rain, snow, or other adverse weather conditions that reduce visibility. The illumination helps pilots navigate safely.

• International Airports

  Threshold lighting is commonly found in international airports worldwide, as it is a standard safety measure for commercial aviation. These lights comply with International Civil Aviation Organization (ICAO) standards and recommendations.

How to choose threshold lighting in airport

There are many factors to consider when choosing the right kind of lighting for a particular space. This is because different spaces have distinct requirements when it comes to lighting.

First and foremost, it is important to consider the intended use of the space. In this case, the airport terminal and what the lighting will be used for. In the context of an airport terminal, lighting can be used for aesthetics, wayfinding, and safety.

The latter entails ensuring that people can see where they are going, especially in low-light conditions. This makes lighting an important consideration in the design of airport terminals because it directly affects the safety of passengers and other airport personnel.

It is also important to consider the location of the airport and the weather patterns in the region. For instance, if the airport is in a location that is usually cloudy, it may need to rely more on ambient lighting during the day. This is not the case for airports in sunny regions that can benefit from natural light.

The type of lighting can also affect the terminal's energy consumption. For this reason, it is important to consider the terminal's energy efficiency goals when choosing lighting. For instance, LED lighting is a popular choice among airport terminals because it is energy efficient and can be used for a variety of purposes. These include aesthetic and safety reasons.

Other than LED lighting, it is important to consider the color temperature of the lighting. This is because different color temperatures can create different atmospheres in different spaces. For instance, in the case of airport lounges, a warmer color temperature can create a more relaxed atmosphere. On the other hand, a cooler temperature can create a more energizing atmosphere in concourse areas.

Finally, it is important to consider the lighting control systems. This is because such systems allow for the customization of lighting to meet the different needs of different spaces and at different times. For instance, dimming controls can be used to adjust the level of lighting in areas where there are few people. This is as opposed to areas that require full lighting.
