SAE AS 5681C:2024-08-12

This SAE Aerospace Standard (AS)/Minimum Operational Performance Specification (MOPS) specifies the minimum performance requirements of remote on-ground ice detection systems (ROGIDS). These systems are ground based. They provide information that indicates whether frozen contamination is present on aircraft surfaces. Section 1 provides information required to understand the need for the ROGIDS, ROGIDS characteristics, and tests that are defined in subsequent sections. It describes typical ROGIDS applications and operational objectives and is the basis for the performance criteria stated in Sections 3 through 5. Section 2 provides reference information, including related documents, definitions, and abbreviations. Section 3 contains general design requirements for the ROGIDS. Section 4 contains the Minimum Operational Performance Requirements for the ROGIDS, which define performance in icing conditions likely to be encountered during ground operations. Section 5 describes environmental test conditions that provide laboratory means of testing the overall performance characteristics of the ROGIDS in conditions that may be encountered in actual operations. Section 6 describes recommended test procedures for demonstrating compliance with Sections 3 and 4. Section 7 contains the operational evaluation requirements for verifying the performance of the ROGIDS when installed for in-service use.
