Next year, the FAA hopes to release a new rule that closes a gap between flight-in-known-icing certification requirements for Part 23 and Part 25 aircraft. Part 25 aircraft weigh more than 12,500 pounds, and more stringent requirements apply to their certification. In the case of icing, however, Part 23 has stricter requirements, that they be “capable of operating safely in continuous maximum and intermittent maximum icing conditions, as described in Appendix C of Part 25.”
Part 25 airplanes “must be able to safely operate” in the same conditions, but there is no definition of what “to safely operate” means. Part 23 regulations provide a clear definition: “‘Capable of operating safely,’ means that airplane performance, controllability, maneuverability and stability must not be less than that required in Part 23, Subpart B.”
