Question #11:

How do weather conditions affect aircraft endurance?

Answer:

There are some weather conditions that may have affect aircraft endurance such as icing, turbulence, high temperature. If we are talking about icing, an aircraft weight and drag increase in this condition. When aircraft gets into turbulence its drag increases too. Also high temperature at flight level reduces thrust of engines so pilots need to apply more power to continue level flight. All of these increase fuel consumption.
