Final answer:
Anti-collision strobes must be illuminated during certain situations in aviation to enhance visibility and prevent collisions.
Step-by-step explanation:
In aviation, anti-collision strobes, also known as aircraft strobe lights, must be illuminated during certain situations to enhance visibility and help prevent collisions. The most common requirement is to illuminate the strobes during takeoff, landing, and when operating on the ground in low visibility conditions such as fog or heavy rain. Strobes are also typically used when crossing runways or taxiing in non-movement areas.
An example of when you must illuminate your anti-collision strobes is during takeoff. The bright flashing lights help other pilots and ground personnel to easily see your aircraft and avoid any potential accidents. This is particularly important at night or in poor weather conditions where visibility may be reduced.
