How does tropopause temperature effect fuel efficency at flight levels? All other things being equal, would ISA -10°C or ISA +10°C be better for fuel efficency?
In addition, if ISA +10°C causes less fuel burn per hour, would it also cause a slower TAS because the air is less dense, thus potentially cutting back on any lb/hr increase?
