What type of sign indicates mandatory instruction in aviation?

• A. Advisory sign
• B. Warning sign
• C. Mandatory instruction sign
• D. Information sign

Answer: (C)

The type of sign that indicates mandatory instruction in aviation is referred to as a mandatory instruction sign. These signs are specifically designed to convey critical information that pilots and ground personnel must follow without exception, such as "Runway Hold Position" or "No Entry." The use of mandatory instruction signs helps ensure safety and compliance with necessary procedures on the airfield. In contrast, advisory signs provide suggestions or recommendations but do not require compliance. Warning signs alert individuals to potential hazards or risks but do not convey specific directives that must be followed. Information signs typically provide general data or notifications, such as location markers and directions, but they do not impose mandatory actions. The clear distinction of the mandatory instruction sign is its role in enforcing compliance, making it essential for safe operations in aviation environments.
