What do yellow signs typically indicate on an airport?

1. Mandatory instructions

2. Runway information

3. Taxiway guidance

4. Area of operations

The correct answer is: Taxiway guidance

Yellow signs on an airport are primarily used for taxiway guidance. These signs provide important information to pilots as they navigate the airport environment. They may indicate taxiway designations, direction to runways, or the location of other critical areas such as holding positions or intersections. When pilots rely on yellow signs, they are receiving essential guidance that helps them safely maneuver on the ground and prepare for their flight operations. The use of yellow for these signs is standardized in the aviation industry to ensure clarity and consistency across various airports. While other colors and sign formats are used for different purposes—such as mandatory instructions, which are often indicated by red signs, and runway information, which tends to be green—the yellow signs specifically focus on aiding pilots in their ground movements.
