Which effect results on a jet engine when ambient temperature increases at constant throttle?

A)Thrust decrease and EGT increase
B)Thrust increase and fuel decrease
C)EGT decrease and thrust increase
D)Fuel increase and thrust decrease

💡 Explanation

When ambient temperature increases the density decreases, affecting the mass flow rate; thermal efficiency is reduced. Constant throttle means less dense air, thus thrust decreases because of reduced mass flow, and Turbine Gas Temperature/Exhaust Gas Temperature will increase, rather than other outcomes.
