This SAE Aerospace Recommended Practice (ARP) document establishes criteria and recommended practices for the use of airborne icing tankers to aid in design and certification of aircraft ice protection systems and components. Several icing tankers are described, along with their capabilities and suggested use. Sample data for these tanker spray systems are included, shown with 14 CF R Parts 25 and 29, Appendix C icing envelopes for continuous maximum and intermittent maximum icing conditions. (Note: In the remainder of this document, the phrase "Appendix C icing envelopes" will be used for brevity.) This ARP is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances. The purpose of this document is to support the objective of the "FAA Inflight Aircraft Icing Plan" of establishing acceptance criteria for icing tankers. To this purpose, the document surveys existing airborne icing tanker technology and provides guidance for the acceptance of icing tanker information for certification purposes. The document provides some, but not all, criteria that shall be considered when selecting and using an icing tanker for artificial inflight icing tests. Use of an airborne icing tanker to obtain certification information shall be negotiated with and approved by a certification office, and included in the certification plan for the aircraft.
