                     TITLE 14--AERONAUTICS AND SPACE
 
CHAPTER I--FEDERAL AVIATION ADMINISTRATION, DEPARTMENT OF TRANSPORTATION 
                               (CONTINUED)
 
PART 121_OPERATING REQUIREMENTS: DOMESTIC, FLAG, AND SUPPLEMENTAL OPERATIONS--
 
          Subpart I_Airplane Performance Operating Limitations
 
Sec. 121.195  Airplanes: Turbine engine powered: Landing limitations: 

Destination airports.

    (a) No person operating a turbine engine powered airplane may take 
off that airplane at such a weight that (allowing for normal consumption 
of fuel and oil in flight to the destination or alternate airport) the 
weight of the airplane on arrival would exceed the landing weight set 
forth in the Airplane Flight Manual for the elevation of the destination 
or alternate airport and the ambient temperature anticipated at the time 
of landing.
    (b) Except as provided in paragraph (c), (d), or (e) of this 
section, no person operating a turbine engine powered airplane may take 
off that airplane unless its weight on arrival, allowing for normal 
consumption of fuel and oil in flight (in accordance with the landing 
distance set forth in the Airplane Flight Manual for the elevation of 
the destination airport and the wind conditions anticipated there at the 
time of landing), would allow a full stop landing at the intended 
destination airport within 60 percent of the effective length of each 
runway described below from a point 50 feet above the intersection of 
the obstruction clearance plane and the runway. For the purpose of 
determining the allowable landing weight at the destination airport the 
following is assumed:
    (1) The airplane is landed on the most favorable runway and in the 
most favorable direction, in still air.
    (2) The airplane is landed on the most suitable runway considering 
the probable wind velocity and direction and the ground handling 
characteristics of the airplane, and considering other conditions such 
as landing aids and terrain.
    (c) A turbopropeller powered airplane that would be prohibited from 
being taken off because it could not meet the requirements of paragraph 
(b)(2) of this section, may be taken off if an alternate airport is 
specified that meets all the requirements of this section except that 
the airplane can accomplish a full stop landing within 70 percent of the 
effective length of the runway.
    (d) Unless, based on a showing of actual operating landing 
techniques on wet runways, a shorter landing distance (but never less 
than that required by paragraph (b) of this section) has been approved 
for a specific type and model airplane and included in the Airplane 
Flight Manual, no person may takeoff a turbojet powered airplane when 
the appropriate weather reports and forecasts, or a combination thereof, 
indicate that the runways at the destination airport may be wet or 
slippery at the estimated time of arrival unless the effective runway 
length at the destination airport is at least 115 percent of the runway 
length required under paragraph (b) of this section.
    (e) A turbojet powered airplane that would be prohibited from being 
taken off because it could not meet the requirements of paragraph (b)(2) 
of this section may be taken off if an alternate airport is specified 
that meets all the requirements of paragraph (b) of this section.
