Minimum Operational Performance Specification for Remote On-Ground Ice Detection Systems
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 Section 3 through Section 5.
Section 2 provides reference information, including related documents, abbreviations, and definitions.
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.
This document has been revised based on further examination of the lists of required and recommended tests by the Ice Detection Working Group. The “recommended” test classification has been changed to “optional” to better reflect the purpose and intended use of these tests. Additionally, some of the optional tests were removed as they were found to be not applicable.
Other changes have been made due to the change in document SAE J1211 (referred to in several places in this document) from an environmental test document to a reliability by design methodology.
The appropriate tool for measuring fluid thickness has been added to 220.127.116.11 d.
