AERODROME BEACON Meaning and
Definition
-
An aerodrome beacon refers to an illuminated signal or navigational aid located at an airport or aerodrome. It is designed to assist pilots and air traffic controllers in identifying the location and boundaries of an aerodrome, particularly during times of low visibility or darkness.
The aerodrome beacon typically consists of a rotating light source placed at the top of a tall structure, such as a tower or mast. This light emits a powerful beam that rotates in a specific pattern, allowing it to be distinguished from other types of lights. The rotation helps pilots identify the aerodrome based on its unique light characteristic and aids in differentiation from nearby beacons or towers.
The purpose of the aerodrome beacon is twofold. Firstly, it provides a visual indication of an aerodrome's presence to pilots who may be approaching the area. Secondly, it serves as a visual reference point, allowing pilots to orient themselves in relation to the aerodrome and its associated runways and taxiways once they are in the vicinity.
These beacons are typically equipped with a fresnel lens to focus and intensify the light from the source, enabling it to be visible over considerable distances. Additionally, they are often equipped with a predetermined color, such as white, green, or red, to distinguish the beacons of different aerodromes or to indicate specific information, such as day/night operations or obstructions on the airfield.
In summary, an aerodrome beacon is a visually distinctive, rotating light mounted on a tall structure that provides pilots with a clear indication of the presence, location, and orientation of an aerodrome, enhancing safety and facilitating navigation during periods of low visibility or darkness.
Etymology of AERODROME BEACON
The word "aerodrome" originated in the early 20th century and is derived from two Greek words: "aero", meaning air, and "drome", meaning runway or course. It was initially used to describe a place where aircraft could take off and land.
The term "beacon" has a different origin. It stems from the Old English word "bēacen", which referred to a sign or signal. Over time, it also came to represent a light or fire used for navigation and warning purposes.
When combined, "aerodrome beacon" refers to a type of navigational aid used at an aerodrome or airport. It typically consists of a tall structure with a bright light on top, providing visual guidance for pilots during low visibility conditions.
