• ED Decision 2007/015/R found in: CS-E Amdt 5 - Engines (Dec 2018)

CS-E 620 Performance Correction ED Decision 2007/015/R (See [AMC E 620](#_DxCrossRefBm1371447756)) (a) All performance results must be corrected to the following assumed conditions of atmospheric pressure and temperature at mean sea level: (1) Pressure. 1013.25 hPa (2) Temperature. 288 K (3) Atmosphere. Dry air (if correction is significant). (b) *Correction of Humidity.* No correction for humidity of the air supply may be made to the power obtained. Humidity corrections appropriate to high atmospheric temperatures, at altitudes up to 4 500 m must be established, however, for each type of turbine Engine, for use in the assessment of aircraft performance in these conditions.
