What color are taxiway location signs?

Taxiway location signs are designed to provide vital information to pilots and ground personnel regarding their position on the airport surface. The standard color scheme for taxiway location signs is black with yellow letters. This color combination ensures high visibility and clarity in various weather conditions and lighting, helping to prevent confusion and enhance safety on the airfield.

The use of black background with yellow text follows the International Civil Aviation Organization (ICAO) guidelines for airport signage, which is consistent across many airports to maintain a universal understanding of airside operations. This color convention helps distinguish taxiway information from other types of signs, such as runway signs, which have different color schemes to convey different messages.

In contrast, the other color schemes mentioned in the choices do not align with the established standards for taxiway location signage, leading to potential misinterpretation and safety issues. Therefore, understanding the color codes is crucial for anyone operating in the airside environment, especially for those holding or pursuing an Airside Vehicle Operator Permit (AVOP).
