# §135.393. Large nontransport category airplanes: Landing limitations: Destination airports.

- (a) No person operating a large nontransport category airplane may take off that airplane at a weight that—
  - (1) Allowing for anticipated consumption of fuel and oil, is greater than the weight that would allow a full stop landing within 60 percent of the effective length of the most suitable runway at the destination airport; and
  - (2) **Is greater than the weight allowable if the landing is to be 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.
- (b) **For the purpose of this section, it is assumed that—**
  - (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.**
