Which type of runway lighting consists of a pair of synchronized flashing lights, one on each side of the runway threshold?

1) Approach lighting
2) Runway edge lighting
3) Runway end lighting
4) Runway threshold lighting

Answer :

Final answer:

The correct answer is 4) Runway threshold lighting. runway threshold lighting, which consists of a pair of synchronized flashing lights on each side of the runway threshold, helping pilots identify the beginning of the runway available for landing.

Explanation:

The correct answer is 4) Runway threshold lighting.

Runway threshold lighting is an essential component of airport runways, marking the beginning of the runway that is available for landing. In particular, these lights are crucial during night operations or in adverse weather conditions, guiding the pilot to the threshold of the runway.

These lights are distinctive because they consist of a pair of synchronized flashing lights located on each side of the runway threshold, making them easily identifiable to incoming aircraft.

These lights differ from approach lighting, which helps pilots recognize the runway's alignment during the final approach, runway edge lighting, which delineates the edges of the runway, and runway end lighting, which marks the end of the runway. Understanding these different lighting systems is crucial for pilots to navigate runways safely.
