Q

When must a cold weather preflight inspection be performed

A
  • if the OAT is 5C or less, or
  • the wing fuel temp is 0C or less, or
  • atmospheric conditions conducive to icing exist, or
  • the aircraft has remained overnight and may have frozen contaminants due to frost or precip
  • if there is residual ice brought in from previous flight, or
  • cold soak ice is suspected in the fuel tank area
