What happens when there is fuel starvation in a turbine engine?

Fuel starvation in a turbine engine refers to a condition where the fuel supply is insufficient for the engine's operation. When this occurs, the engine may not receive the necessary amount of fuel to sustain combustion, leading to a flameout state. Flameout occurs when the fuel-air mixture in the combustion chamber becomes too lean to support combustion, resulting in the engine losing power and potentially shutting down.

This condition can happen for various reasons, such as fuel pump failure, fuel blockage, or problems with fuel control systems. If fuel starvation persists, the engine may completely go out, leading to a flameout situation. The quick response to this issue is critical for pilots to regain power or perform an emergency landing if necessary.

The other options don't accurately describe the effects of fuel starvation. While complete engine shutdown and overheating could be potential consequences of other issues, they are not the primary or deterministic outcomes of fuel starvation. Running at maximum efficiency is contrary to the situation, as the lack of sufficient fuel would lead to inefficiencies and operational instability.
