Sec. 25.105  Takeoff.



    (a) The takeoff speeds described in Sec. 25.107, the accelerate-

stop distance described in Sec. 25.109, the takeoff path described in 

Sec. 25.111, and the takeoff distance and takeoff run described in 

Sec. 25.113, must be determined--

    (1) At each weight, altitude, and ambient temperature within the 

operational limits selected by the applicant; and

    (2) In the selected configuration for takeoff.

    (b) No takeoff made to determine the data required by this section 

may require exceptional piloting skill or alertness.

    (c) The takeoff data must be based on--

    (1) In the case of land planes and amphibians:

    (i) Smooth, dry and wet, hard-surfaced runways; and

    (ii) At the option of the applicant, grooved or porous friction 

course wet, hard-surfaced runways.

    (2) Smooth water, in the case of seaplanes and amphibians; and

    (3) Smooth, dry snow, in the case of skiplanes.

    (d) The takeoff data must include, within the established 

operational limits of the airplane, the following operational correction 

factors:

    (1) Not more than 50 percent of nominal wind components along the 

takeoff path opposite to the direction of takeoff, and not less than 150 

percent of nominal wind components along the takeoff path in the 

direction of takeoff.

    (2) Effective runway gradients.
