Which statement describes a function of the exhaust system in an aircraft?

The function of the exhaust system in an aircraft is primarily to expel waste gases produced during the combustion process and to help control the temperature of the engine components. As the engine burns fuel and air, it produces exhaust gases that need to be safely directed away from the engine to prevent them from interfering with its operation. The exhaust system facilitates the removal of these gases, thereby maintaining optimal performance and safety.

Additionally, the design of the exhaust system can influence engine cooling by dissipating heat away from the engine. This is crucial to avoid overheating, which can lead to engine failure. By efficiently managing the waste gases and contributing to temperature control, the exhaust system plays a vital role in the overall operation and longevity of the engine, ensuring that it operates within safe temperature limits.
