An aerodrome beacon is a very bright light that helps planes locate an airport at night or in low visibility conditions. It's like a lighthouse for planes. The beacon is usually on top of a tall tower or building at the airport and can be seen from very far away.
The colors of the aerodrome beacon are also important. They tell pilots important information about the airport. If the beacon is flashing white, it means that the airport is open. If it’s green, it means that the airport is a civilian airport. If it is red and white, then it’s an airport with both civilian and military aircrafts. If it’s only red, then it means that the airport is closed and no one can fly in or out.
Overall, the aerodrome beacon is a very important tool for pilots because it helps them navigate and land safely at the airport.
