What should pilots do upon detecting significant icing conditions?

Upon detecting significant icing conditions, pilots should implement the necessary anti-ice procedures. This action is crucial because icing can severely affect aircraft performance, handling characteristics, and safety. The CRJ 200, like other aircraft, is equipped with anti-icing and de-icing systems designed to mitigate the hazards associated with ice accumulation on critical surfaces.

By following the established anti-ice procedures, pilots can ensure that the aircraft maintains proper aerodynamics and control, reducing the risk of ice-related incidents during flight. This can include activating wing and engine anti-ice systems before takeoff and ensuring that ice accumulation is actively monitored and managed throughout the flight.

The other options do not adequately address the immediate need for safety regarding icing conditions. For example, proceeding with takeoff as scheduled ignores the potential risks associated with ice. Consulting maintenance personnel may be necessary if an issue arises, but the immediate priority is to ensure that the aircraft can safely operate in the current conditions. Similarly, while requesting a flight delay can be prudent in certain situations, implementing anti-ice procedures is essential to mitigate risks in real-time when icing is already detected.
