What is the color scheme for location signs on an airfield?

Location signs on an airfield follow a specific color scheme to convey critical information to pilots and drivers. The correct choice is characterized by a black background with yellow letters. This color combination is designed for high visibility and contrast, ensuring that the signs can be easily read from a distance under varying lighting conditions.

The use of black and yellow is consistent with standard aviation practices, helping to differentiate these signs from others that indicate different types of information, such as regulatory or warning signs. Black with yellow is widely recognized as an effective scheme to denote location information, which is essential for airfield navigation.

In contrast, other color schemes represent different types of signs: for example, red and white typically indicate a stop or warning, while green and black might be used for directions or guidance on taxiways. Therefore, understanding the specific significance of the black and yellow scheme is crucial for maintaining safety and efficiency on the airfield.
