§25.1533 Additional operating limitations

(See AMC 25.1533) (a) Additional operating limitations must be established as follows: (1) The maximum take-off weights must be established as the weights at which compliance is shown with the applicable provisions of this CS–25 (including the take-off climb provisions of CS 25.121 (a) to (c), for altitudes and ambient temperatures). (2) The maximum landing weights must be established as the weights at which compliance is shown with the applicable provisions of this CS–25 (including the landing and approach climb provisions of CS 25.119 and 25.121 (d) for altitudes and ambient temperatures). (3) The minimum take-off distances must be established as the distances at which compliance is shown with the applicable provisions of this CS–25 (including the provisions of CS 25.109 and 25.113, for weights, altitudes, temperatures, wind components, runway surface conditions (dry and wet) and runway gradients) for smooth, hard-surfaced runways. Additionally, at the option of the applicant, wet runway take-off distances may be established for runway surfaces that have been grooved or treated with a porous friction course and may be approved for use on runways where such surfaces have been designed, constructed and maintained in a manner acceptable to the Agency. (See AMC 25.1533(a)(3).) (b) The extremes for variable factors (such as altitude, temperature, wind, runway gradients) are those at which compliance with the applicable provisions of this CS–25 is shown. (c) For aeroplanes certified in accordance with CS 25.1420(a)(1) or (a)(2), an operating limitation must be established to: (1) Prohibit intentional flight, including take-off and landing, into icing conditions defined in Appendix O for which the aeroplane has not been certified to safely operate; and (2) Require exiting all icing conditions if icing conditions defined in Appendix O are encountered for which the aeroplane has not been certified to safely operate.
