What does "known icing" indicate about the PC-12's capabilities?

The term "known icing" indicates specific operational capabilities of the PC-12, particularly regarding its certification for flight in conditions where icing is present. The correct interpretation of this term is that the aircraft is certified for flight in known icing conditions. This means that the PC-12 is designed and equipped to handle certain levels of ice accumulation, which can occur in flight when flying through clouds containing supercooled water droplets.

This certification signifies that the aircraft meets the necessary regulations and standards established for safe operation in icing environments, allowing pilots to plan flights confidently in conditions where icing may be encountered. Therefore, it is essential for pilots to understand that while the PC-12 is capable of flying in icing conditions, they must still manage the aircraft within the defined limitations to ensure safety.

The other options do not accurately reflect the capabilities related to known icing and exclude critical factors regarding the aircraft’s performance and operational standards.
