CS-VLA 1587  Performance information

ED Decision 2003/18/RM

(a)                            General. For each aeroplane, the following information must be furnished

(1)                            The take-off distance determined under CS-VLA 51, the airspeed at the 15 m height, the aeroplane configuration (if pertinent), the kind of surface in the tests, and the pertinent information with respect to cowl fiap position, use of flight path control devices, and use of the landing gear retraction system.

(2)                            The landing distance determined under CS-VLA 75, the aeroplane configuration (if pertinent), the kind of surface used in the tests, and the pertinent information with respect to flap position and the use of flight path control devices.

(3)                            The steady rate or gradient of climb determined under CS-VLA 65 and 77, the airspeed, power, and the aeroplane configuration.

(4)                            The calculated approximate effect on take-off distance (sub-paragraph (a)(1) of this paragraph), landing distance (sub-paragraph (a)(2) of this paragraph), and steady rates of climb (sub-paragraph (a)(3) of this paragraph), of variations in altitude and temperature. (See AMC VLA 1587(a)(4).)

(5)                            The maximum atmospheric temperature at which compliance with the cooling provisions of CS-VLA 1041 to 1047 is shown.

(b)                            Skiplanes. For skiplanes a statement of the approximate reduction in climb performance may be used instead of complete new data for skiplane configuration, if -

(1)                            The landing gear is fixed in both landplane and skiplane configurations;

(2)                            The climb requirements are not critical; and

(3)                            The climb reduction in the skiplane configurations is small (0.15 to 0.25 m/s (30 to 50 feet per minute)).

(c)                            Information concerning normal procedures

(1)                            The demonstrated crosswind velocity and procedures and information pertinent to operation of the aeroplane in crosswinds, and

(2)                            The airspeeds, procedures, and information pertinent to the use of the following airspeeds:

(i)                             The recommended climb speed and any variation with altitude.

(ii)                            VX (speed for best angle of climb) and any variation with altitude.

(iii)                           The approach speeds, including speeds for transition to the balked landing condition.

(d)                            An indication of the effect on take-off distance of a grass surface as determined from at least one take-off measurement on short mown dry grass must be furnished.
