FIKI: Do You Really Need It?

The phrases "all weather" and "single-engine airplane" belong in the same sentence only for a select few pilots whose tolerance for risk is best described as elastic. What has always been true, remains true: One mans routine trip through cold clouds is another mans (or womans) agita-inducing nightmare. Of late, the industry has made remarkable strides in giving even the most risk-tolerant pilots better tools to detect threatening weather and deal with its consequences. Still, even for many experienced pilots, structural icing represents an exceptional terror. Ice forecasting has improved-even in the last five years-but intensity forecasting is still uncertain at best. And many pilots worry-irrationally in our view-about the FAA-legal definition of known icing. When is it legal to depart? When is it not? Do so-called inadvertent ice protection systems really buy you any risk mitigation? (Short answer: yes.) For some pilots, worrying about these fine details leads to distracting hand wringing. It really shouldnt. Seeing an opportunity in this conundrum, Cirrus Aircraft (formerly Cirrus Design) recently developed and will soon certify and ship what is, in our view, the most sophisticated and possibly effective integrated approach to ice protection for any single-engine piston airplane weve seen. And thats saying a lot, given the excellent TKS-based known-ice package that Mooney has offered for years, not to mention inadvertent and certified systems for Beechcraft and Cessna models, including the composite Bend, Oregon-built Corvallis line. Prior to Cessna buying the then-Columbia Aircraft Company, Columbia had dabbled in electric ice protection systems, but without much success. TKS is now the market leader in new aircraft de-icing systems. By way of definition, "inadvertent" means a system is designed to provide some margin of protection without being certified for flight into known ice.

Key Takeaways:

  • Structural icing is a persistent and significant risk for single-engine aircraft pilots, limiting utility and often causing anxiety due to uncertain forecasting and legal definitions.
  • Cirrus Aircraft has introduced a highly sophisticated and integrated "flight-into-known-ice" (FIKI) protection system for its SR22, upgrading its previous "inadvertent" system with expanded coverage, redundancy, and enhanced components.
  • This TKS-based FIKI system is deeply integrated with the Garmin Perspective EFIS for comprehensive system monitoring, leverages advanced XM Wx icing forecasts, and utilizes the aircraft's turbocharging to significantly mitigate ice flying risks and enhance operational utility.
