If ice is detected on one of the ice detector probes, the respective ice protection systems will automatically be activated.

• A. TRUE
• B. FALSE
• C. Not Automatically
• D. Only after ground checks

Answer: (B)

Ice detectors point out icing conditions, but they don’t automatically trigger the ice protection system in all aircraft. Activation is typically controlled by the pilot (a switch or mode like AUTO) or by a system logic that requires the crew to enable anti-ice/de-ice or rely on specific automatic conditions. Detecting ice on a probe signals the system to consider protection, but it isn’t a guaranteed automatic deployment. That’s why the statement isn’t universally true.
