OPERATIONS--Table of Contents

 

          Subpart I_Airplane Performance Operating Limitations

 

Sec. 121.185  Airplanes: Reciprocating engine-powered: Landing 

limitations: Destination airport.



    (a) Except as provided in paragraph (b) of this section no person 

operating a reciprocating engine powered airplane may take off that 

airplane, unless its weight on arrival, allowing for normal consumption 

of fuel and oil in flight, would allow a full stop landing at the 

intended destination within 60 percent of the effective length of each 

runway described below from a point 50 feet directly above the 

intersection of the obstruction clearance plane and the runway. For the 

purposes 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 (forecast for the expected time 

of arrival), the ground handling characteristics of the type of 

airplane, and other conditions such as landing aids and terrain, and 

allowing for the effect of the landing path and roll of not more than 50 

percent of the headwind component or not less than 150 percent of the 

tailwind component.

    (b) An airplane that would be prohibited from being taken off 

because it could not meet the requirements of paragraph (a)(2) of this 

section may be taken off if an alternate airport is specified that meets 

all of 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.

    (c) This section does not apply to large nontransport category 

airplanes operated under Sec. 121.173(c).
