CHAPTER I--FEDERAL AVIATION ADMINISTRATION, DEPARTMENT OF TRANSPORTATION 
                               (CONTINUED)
 
PART 135_OPERATING REQUIREMENTS: COMMUTER AND ON DEMAND OPERATIONS AND RULES 
 
          Subpart I_Airplane Performance Operating Limitations
 
Sec. 135.389  Large nontransport category airplanes: Takeoff limitations.

    (a) No person operating a large nontransport category airplane may 
take off that airplane at a weight greater than the weight that would 
allow the airplane to be brought to a safe stop within the effective 
length of the runway, from any point during the takeoff before reaching 
105 percent of minimum control speed (the minimum speed at which an 
airplane can be safely controlled in flight after an engine becomes 
inoperative) or 115 percent of the power off stalling speed in the 
takeoff configuration, whichever is greater.
    (b) For the purposes of this section--
    (1) It may be assumed that takeoff power is used on all engines 
during the acceleration;
    (2) Not more than 50 percent of the reported headwind component, or 
not less than 150 percent of the reported tailwind component, may be 
taken into account;
    (3) The average runway gradient (the difference between the 
elevations of the endpoints of the runway divided by the total length) 
must be considered if it is more than one-half of one percent;
    (4) It is assumed that the airplane is operating in standard 
atmosphere; and
    (5) For takeoff, effective length of the runway means the distance 
from the end of the runway at which the takeoff is started to a point at 
which the obstruction clearance plane associated with the other end of 
the runway intersects the runway centerline.
