    (a) No person operating a nontransport category airplane may take 
off that airplane at a weight that--

made on the runway--
    (i) With the greatest effective length in still air; and
    (ii) Required by the probable wind, taking into account not more 
than 50 percent of the headwind component or not less than 150 percent 
of the tailwind component.

    (1) The airplane passes directly over the intersection of the 
obstruction clearance plane and the runway at a height of 50 feet in a 
steady gliding approach at a true indicated airspeed of at least 1.3 
VSo;
    (2) The landing does not require exceptional pilot skill; and
    (3) The airplane is operating in standard atmosphere.
