With winter nearly in full swing north of the equator, it’s only a matter of time before instrument-rated pilots will need to make decisions about how to escape from icing situations, whether that be before takeoff or while en route. Ice adds weight and acts as a lift spoiler across wings and tail surfaces. Ice can also affect engine operations for all aircraft. Ice protection is broadly categorized as either anti- or deicing, depending on the equipment installed and the certification of the aircraft.
How Aircraft Ice Protection Works
Key Takeaways:
- Aircraft icing is a critical hazard that severely impacts lift, adds weight, and impairs engine and sensor operations, necessitating careful pilot decision-making.
- The primary strategy for pilots to manage icing is to avoid or quickly exit conditions of visible moisture below 37 degrees Fahrenheit.
- Aircraft utilize various anti-icing (prevents ice) and de-icing (removes ice) systems, including pneumatic boots, heated leading edges, fluid-based TKS, and heating for pitot tubes, engines, and propellers.
