    Federal Aviation Regulations


    121.7   Definitions.

    The following definitions apply to those sections of part 121 that apply to ETOPS:

    ETOPS Area of Operation means one of the following areas:

    (1) For turbine-engine-powered airplanes with two engines, an area beyond 60 minutes from an adequate airport, computed using a one-engine-inoperative cruise speed under standard conditions in still air.

    (2) For turbine-engine-powered passenger-carrying airplanes with more than two engines, an area beyond 180 minutes from an adequate airport, computed using a one-engine-inoperative cruise speed under standard conditions in still air.



    North Polar Area means the entire area north of 78° N latitude.

    South Polar Area means the entire area South of 60° S latitude.

    §121.161   Airplane limitations: Type of route.

    (a) Except as provided in paragraph (e) of this section, unless approved by the Administrator in accordance with Appendix P of this part and authorized in the certificate holder's operations specifications, no certificate holder may operate a turbine-engine-powered airplane over a route that contains a point—

    (1) Farther than a flying time from an Adequate Airport (at a one-engine-inoperative cruise speed under standard conditions in still air) of 60 minutes for a two-engine airplane or 180 minutes for a passenger-carrying airplane with more than two engines;

    (2) Within the North Polar Area; or

    (3) Within the South Polar Area.

    ---------------------------------------------------------------------------



    ============================================================

    Appendix P to Part 121—Requirements for ETOPS and Polar Operations


    (i) 240-minute ETOPS in the North Polar Area, in the area north of the NOPAC, and in the Pacific Ocean north of the equator. (1) The FAA grants approval to conduct 240-minute ETOPS authority with maximum diversion times in the North Polar Area, in the area north of the NOPAC area, and the Pacific Ocean area north of the equator as an extension to 180-minute ETOPS authority to be used on an exception basis. This exception may be used only on a flight-by-flight basis when an ETOPS Alternate Airport is not available within 180 minutes. In that case, the nearest available ETOPS Alternate Airport within 240 minutes diversion time must be specified in the dispatch or flight release.  

    THERE IS NO SIMILAR EXCEPTION FOR THE SOUTH POLAR AREA.

    Tony,

    It is not because of the cold, it is because there is no place to land.  When I flew over the north pole region there was always a place to divert to in an emergency.  There are airports in Alaska, Canada, Greenland, Iceland, Norway, and of course. Russa.

    When flying into Little America - McMurdo  from Christchurch, NZ my only divert was back to NZ.  There is nothing close to most of Antarctia but ocean.
