Characterizations of Aircraft Icing Conditions
AIR5396
This SAE Aerospace Information Report (AIR) provides various graphical displays of atmospheric variables related to aircraft icing conditions in natural clouds. It is intended as a review of recent developments on the subject, and for stimulating thought on novel ways to arrange and use the available data. Included in this Report is FAR 25 (JAR 25) Appendix C, the established Aircraft Icing Atmospheric Characterization used for engineering design, development, testing and certification of civilian aircraft to fly in aircraft icing conditions.
Rationale: This document need to be updated to reflect current understanding of the icing envelopes, including the addition of Part 25/29 Appendix O, and Part 33 Appendix D. The sample historical methodology also needs to be updated and placed into context with the current methodology endorsed by the certification authorities.
