(a) No person may take off any transport category airplane (other than
a turbine-engine-powered airplane certificated after September 30, 1958)
unless --
(1) The takeoff weight does not exceed the authorized maximum takeoff
weight for the elevation of the airport of takeoff;
(2) The elevation of the airport of takeoff is within the altitude
range for which maximum takeoff weights have been determined;
(3) Normal consumption of fuel and oil in flight to the airport of
intended landing will leave a weight on arrival not in excess of the
authorized maximum landing weight for the elevation of that airport; and
(4) The elevations of the airport of intended landing and of all
specified alternate airports are within the altitude range for which the
maximum landing weights have been determined.
(b) No person may operate a turbine-engine-powered transport category
airplane certificated after September 30, 1958, contrary to the Airplane
Flight Manual, or take off that airplane unless --
(1) The takeoff weight does not exceed the takeoff weight specified in
the Airplane Flight Manual for the elevation of the airport and for the
ambient temperature existing at the time of takeoff;
(2) Normal consumption of fuel and oil in flight to the airport of
intended landing and to the alternate airports will leave a weight on
arrival not in excess of the landing weight specified in the Airplane
Flight Manual for the elevation of each of the airports involved and for
the ambient temperatures expected at the time of landing;
(3) The takeoff weight does not exceed the weight shown in the Airplane
Flight Manual to correspond with the minimum distances required for
takeoff, considering the elevation of the airport, the runway to be used,
the effective runway gradient, the ambient temperature and wind component
at the time of takeoff, and, if operating limitations exist for the
minimum distances required for takeoff from wet runways, the runway
surface condition (dry or wet). Wet runway distances associated with
grooved or porous friction course runways, if provided in the Airplane
Flight Manual, may be used only for runways that are grooved or treated
with a porous friction course (PFC) overlay, and that the operator
determines are designed, constructed, and maintained in a manner
acceptable to the Administrator.
(4) Where the takeoff distance includes a clearway, the clearway
distance is not greater than one-half of --
(i) The takeoff run, in the case of airplanes certificated after
September 30, 1958, and before August 30, 1959; or
(ii) The runway length, in the case of airplanes certificated after
August 29, 1959.
(c) No person may take off a turbine-engine-powered transport category
airplane certificated after August 29, 1959, unless, in addition to the
requirements of paragraph (b) of this section --
(1) The accelerate-stop distance is no greater than the length of the
runway plus the length of the stopway (if present); and
(2) The takeoff distance is no greater than the length of the runway
plus the length of the clearway (if present); and
(3) The takeoff run is no greater than the length of the runway.
