AMC 25.119 Landing climb: all-engines-operating ED Decision 2020/024/R In establishing the thrust specified in [CS 25.119](#_DxCrossRefBm1709820701), either – a. Engine acceleration tests should be conducted using the most critical combination of the following parameters: i. Altitude; ii. Airspeed; iii. Engine bleed; iv. Engine power off-take; likely to be encountered during an approach to a landing airfield within the altitude range for which landing certification is sought; or b. The thrust specified in [CS 25.119](#_DxCrossRefBm1709820701) should be established as a function of these parameters. For aeroplanes equipped with a reduced go-around (RGA) thrust or power function, the climb requirements specified in [CS 25.119](#_DxCrossRefBm1709820701) are applicable with the RGA function active. During the determination of the maximum thrust or power specified in AMC 25.119 a. and b. the thrust or power controls should be moved to the RGA thrust or power setting. This is consistent with an AFM all‑engines-operating go-around procedure which recommends the use of an RGA function (see [AMC 25.143(b)(4)](#_DxCrossRefBm1709820779)). In exceptional circumstances such as in the presence of wind shear or of unplanned obstacles, the flight crew may elect to use go-around thrust or power that exceeds the RGA setting. However, the applicant is not required to provide AFM climb gradient performance for this situation. If an AFM go-around procedure is approved to use thrust or power above the RGA setting, then the climb requirements of [CS 25.119](#_DxCrossRefBm1709820701) will apply at the higher thrust or power setting.
