SAE ARP4101/3A

This document recommends criteria for the design and installation of flight crew rest facilities (FCRF) on transport category aircraft when operations with an augmented flight crew are performed. NOTE: Within this ARP, the term “must” will indicate items required for compliance with outside known government regulations, especially 14 CFR Part 117. “Shall” describes sections which are required if this ARP is used as a means of compliance. The term “should” will indicate optional requirements, preferences, and recommendations of the approving SAE committee. Wherever noted and bracketed as [FAA] or [EASA], this document includes agency regulations for reference that are not otherwise evaluated herein. The Federal Aviation Administration enacted updated flight time and duty time regulations for flight crew members (14 CFR Part 117) effective January 4, 2014. The regulation defined three levels of in-flight rest facilities: Class 1, Class 2, and Class 3. The maximum allowable flight duty period limitations vary based on the FAA-approved class of the in-flight rest facility. Similarly, EASA enacted Commercial Specification - Flight Time Limitation (CS-FTL) regulations, also referenced in this ARP.
