A Flight Engineer is a specialized member of an aircraft's flight crew responsible for monitoring and managing various systems during a flight. They ensure that engines, fuel, and electrical systems operate efficiently and safely. Flight Engineers often work alongside pilots to assist with pre-flight checks and in-flight adjustments. In modern aviation, the role of a Flight Engineer has become less common due to advancements in technology, such as automated systems and glass cockpits. However, they are still essential in some larger aircraft, where their expertise helps maintain optimal performance and safety throughout the flight.
