          Subpart I_Airplane Performance Operating Limitations

 

Sec. 121.177  Airplanes: Reciprocating engine-powered: Takeoff 

limitations.



    (a) No person operating a reciprocating engine powered airplane may 

takeoff that airplane unless it is possible--

    (1) To stop the airplane safely on the runway, as shown by the 

accelerate stop distance data, at any time during takeoff until reaching 

critical-engine failure speed;

    (2) If the critical engine fails at any time after the airplane 

reaches critical-engine failure speed V1, to continue the 

takeoff and reach a height of 50 feet, as indicated by the takeoff path 

data, before passing over the end of the runway; and

    (3) To clear all obstacles either by at least 50 feet vertically (as 

shown by the takeoff path data) or 200 feet horizontally within the 

airport boundaries and 300 feet horizontally beyond the boundaries, 

without banking before reaching a height of 50 feet (as shown by the 

takeoff path data) and thereafter without banking more than 15 degrees.

    (b) In applying this section, corrections must be made for the 

effective runway gradient. To allow for wind effect, takeoff data based 

on still air may be corrected by taking into account not more than 50 

percent of any reported headwind component and not less than 150 percent 

of any reported tailwind component.

    (c) This section does not apply to large nontransport category 

airplanes operated under Sec. 121.173(c).
