Which statement about anti-ice indicators is correct?

• A. They depend on weather information, icing forecasts, and warnings
• B. They are solely based on pilot judgment
• C. They are not monitored during flight
• D. They are only checked on the ground

Answer: (A)

Anti-ice indicators are driven by weather information, icing forecasts, and warnings. They are designed to reflect current and anticipated icing conditions and guide the crew on when to engage anti-ice systems. In flight, crews receive weather updates and ice warnings, and the aircraft’s ice-detection and alert systems monitor conditions continuously. This means the indicators rely on external data and official warnings rather than being based solely on pilot judgment, and they are actively monitored during flight rather than only checked on the ground.
