                     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. 121.197  Airplanes: Turbine engine powered: Landing limitations: 

Alternate airports.

    No person may list an airport as an alternate airport in a dispatch 
or flight release for a turbine engine powered airplane unless (based on 
the assumptions in Sec. 121.195 (b)) that airplane at the weight 
anticipated at the time of arrival can be brought to a full stop landing 
within 70 percent of the effective length of the runway for 
turbopropeller powered airplanes and 60 percent of the effective length 
of the runway for turbojet powered airplanes, from a point 50 feet above 
the intersection of the obstruction clearance plane and the runway. In 
the case of an alternate airport for departure, as provided in Sec. 
121.617, allowance may be made for fuel jettisoning in addition to 
normal consumption of fuel and oil when determining the weight 
anticipated at the time of arrival.
