Which sign would indicate that a taxiway is closed?

1. Runway hold position sign

2. Taxiway closure sign

3. Mandatory instruction sign

4. Information sign

The correct answer is: Taxiway closure sign

A taxiway closure sign is specifically designed to indicate that a particular taxiway is closed to all aircraft and vehicles. This sign typically features an orange background with black letters stating "TAXIWAY CLOSED," which is easily recognizable to pilots and ground personnel. The primary purpose of this sign is to provide clear and immediate information regarding the status of the taxiway, ensuring safety by preventing aircraft from inadvertently entering a closed area. In contrast, the other signs mentioned serve different functions. A runway hold position sign is used to inform pilots that they should not enter the runway environment without clearance. Mandatory instruction signs convey important instructions that must be followed, often relating to operational procedures on the airfield. Information signs provide general information, such as directing pilots to specific locations, but do not indicate any restrictions or closures. Thus, the clarity and specificity of the taxiway closure sign make it the correct indicator in this scenario.
