What effect, if any, does high ambient temperature have upon the thrust output of a turbine engine
A. Thrust will be reduced due to the decrease in air density.
B. Thrust will remain the same, but turbine temperature will be higher.
C. Thrust will be higher because more heat energy is extracted from the hotter air.
