What should a pilot do if they notice ice formation during taxi?

When a pilot notices ice formation during taxi, the best course of action is to communicate with ground control and, if necessary, return for re-de-icing. Ice formation can significantly impact the aircraft's performance, control surfaces, and handling characteristics. By notifying ground control, the pilot ensures that the situation is appropriately managed, and they can receive guidance on the safest course of action, which may include stopping for de-icing procedures before continuing to the runway.

This approach emphasizes safety and adherence to operational protocols, as ice can lead to increased drag and reduced lift, potentially affecting the aircraft's ability to take off safely. Returning for de-icing is crucial to ensure that the aircraft is in optimal condition for flight, preventing any issues that could arise once airborne.
