Multiple Choice

What type of markings are used near the threshold to help pilots during landings?

Threshold lights are specifically used to assist pilots during landings as they indicate the beginning of the runway that is safe for landing. These lights provide critical visual guidance, particularly during low visibility conditions, by illuminating the physical threshold of the runway. When pilots prepare to land, seeing clear indicators of the runway's start is essential for ensuring they align correctly and safely touch down. In contrast, runway edge lights assist with visibility along the edges of the runway but do not mark the threshold itself. Aiming points are markings on the runway used to help pilots judge their landing approach, while taxiway lines are used to guide aircraft on the ground, separate from the runway area. The primary purpose of threshold lights is to denote the start of the runway and ensure pilots have a clear visual reference for safe landings.
