AMC 27.1587(b)(3) Performance Information

• ED Decision 2018/007/R found in: CS-27 Amdt 10 - Small Rotorcraft (Feb 2023)

AMC 27.1587(b)(3) Performance Information ED Decision 2018/007/R a. Explanation The rotorcraft flight manual (RFM) is an important element in the certification process of the rotorcraft for approval with ditching or emergency flotation provisions. The material may be presented in the form of a supplement or a revision to the basic manual. This material should include: (1) A statement in the ‘Limitations’ section stating that the rotorcraft is approved for ditching or emergency flotation, as appropriate. If certification with ditching provisions is obtained in a segmented fashion (i.e. one applicant performing the safety equipment installation and operations portion and another designing and substantiating the safety equipment’s performance and deployment facilities), the RFM limitations should state that the ditching provisions are not approved until all the segments are completed. The outstanding ditching provisions for a complete certification should be identified in the ‘Limitations’ section. (2) Procedures and limitations for the inflation of a flotation device. (3) A statement in the performance information section of the RFM, identifying the substantiated sea conditions and any other pertinent information. If substantiation was performed using the default North Sea wave climate (JONSWAP), the maximum substantiated significant wave height (Hs) should be stated. If extended testing was performed in accordance with the [AMC to 27.801(e) and 27.802(c)](#_DxCrossRefBm8893883) to demonstrate that the target level of capsize probability can be reached without any operational limitations, this should also be stated. If substantiation was performed for other sea conditions, the maximum substantiated significant wave height (Hs) and the limits of the geographical area represented should be stated. (4) Recommended rotorcraft water entry attitude and speed. (5) Procedures for the use of safety equipment. (6) Egress and life raft entry procedures.
