What describes a location sign on the taxiway?

A location sign on the taxiway is represented by a black sign with a single letter that indicates the specific taxiway designation. These signs are crucial for pilots and ground personnel to understand their location on the airport's taxiway system, helping to ensure safe and efficient navigation on the airside of the airport. The use of a single letter provides a quick and clear reference point as aircraft taxi, allowing for the management of traffic and communication about locations.

In contrast, white signs typically indicate gates or terminal information, while red signs are used to convey warnings or prohibitions, such as hold short instructions or runway incursions. Green signs are generally utilized to provide positive guidance, signaling directions towards exits or paths to follow. Understanding these distinctions is essential for those operating on the airside to maintain safety and avoid confusion.
