The aviation industry depends on correct terms and phrases to be used in every conversation. When it comes to approach lights, there are a few commonly used synonyms like runway lighting, guidance lighting, approach runway, and landing lights. These lights help pilots to get a clear view of the runway as they approach for landing. They are usually installed at a fixed distance from the runway and guide the pilot towards the centerline of the runway. Relying on efficient approach lights, pilots have better visibility, and they can land safely by avoiding any kind of mishap or accident. Precision approach path indicator (PAPI) lights and visual approach slope indicator (VASI) lights are other popular synonyms for approach lights.
