CS-E 620 Performance Correction

(See AMC E 620)

(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.
