This route follows the same track as route AT26 until the SE trade winds are found, from where a more westerly route can be taken to the equator passing close to Fernando de Noronha island. As far as the equator, the same waypoints can be used as in AT26. The equator is crossed in about longitude 30 °W (WP AT278) and the great circle route is taken from there either to Bermuda or direct to the port of destination. This route is not recommended during the North Atlantic hurricane season, but as Cape Horn will have been doubled probably during the most favourable months, which are the southern summer months of December to February, this passage will reach the North Atlantic at the end of winter. As the optimum time for rounding Cape Horn does not fit in with the best arrival time in North America, some alternatives may have to be considered to avoid a winter arrival in the USA. This can be accomplished by spending some time en route in Brazil, Lesser Antilles, or Bermuda. See also routes AT21, AN77, and AN78 (pages 172, 92 and 94). The direct route north of the equator passes through the NE trades which normally last as far as latitude 25 °N from where the Horse Latitudes will have to be crossed.
