If you see flashing lights approaching you while at the Decision Altitude, what are these lights known as?

Flashing lights that are seen while at the Decision Altitude are referred to as rabbit lights. These lights serve a specific purpose in aviation, particularly in the context of an approach to landing. Rabbit lights are typically a series of adjustable threshold lights that illuminate the runway and are designed to assist pilots in safely navigating their final approach. They provide visual cues that help in identifying the runway environment, particularly when a pilot is making important decisions regarding landing.

The incorrect options each serve different functions in aviation. Warning lights generally indicate hazards or alerts but do not specifically pertain to landing. Landing lights are used primarily to illuminate the runway during landing and takeoff, rather than being a specific guide at Decision Altitude. Navigational lights help with orientation in the airspace but are not specifically connected to the runway environment in the same way that rabbit lights are. Understanding the role of each type of light aids pilots in making informed decisions during critical flight phases.
