Re: Fuel consumption and SAT
I have to agree with Hawk37 that a slight increase in fuel use will occur. Fuel flow is increased, but TAS is also increased. Typically, the Fuel Flow increase as a percentage is slightly higher than the TAS increase.
In cruise it's generally not a significant factor, however, additional climb fuel in hotter than standard conditions will make a significant difference to the overall sector fuel use.
