Do You Know Ice?

Februarys Cowboy and Cowards sparked some passionate responses about known icing and my assertion that known icing is observed icing. To better understand known icing, we need to look at the concept from definitional, legal, and safety perspectives.

Key Takeaways:

  • "Known icing" is fundamentally defined by observed ice accretion on an aircraft, differentiating it from forecasted or potential icing, despite some regulatory ambiguities.
  • Legal enforcement actions concerning icing primarily target a pilot's failure to take appropriate action after *observing* actual ice, rather than merely entering conditions with forecasted icing.
  • Prudent pre-flight planning is crucial, requiring pilots to develop alternative courses of action and exit strategies to be implemented if potential icing conditions become observed.
