    Interesting. As far for the 737 the minimum fuel temperature is -43°C, or 3°C above the fuel freezing point temperature (JetA -40, JetA1 -47, JetB-50) whichever is higher...On legs of less than 7 hours it barely reaches -25, but definitely tropopause levels are different on all latitudes.

    I found very interesting this article about Polar Operations by Boeing http://www.boeing.com/commercial/aer...lar_story.html

      Thanks. Love the AERO library.

      Interesting that an alternate strategy to descent is to increase mach and thus TAT.
