What color and shape are taxiway locator signs?

Taxiway locator signs are standardized to ensure pilots and vehicle operators can easily identify their location on the airport's taxiway system. These signs are characterized by a black background with yellow letters, which provides high contrast and visibility. This design helps in clearly communicating important information such as taxiway identifiers and enhances safety by reducing the risk of misidentification in various lighting conditions.

The use of yellow letters on a black background adheres to international aviation standards, ensuring consistency across various airport environments, which is essential for effective navigation and safety on the airside. Understanding these specifics is crucial for anyone operating vehicles in the vicinity of airport transport operations to ensure compliance and awareness on the airfield.
