Final answer:
One possible drawback of a fuel injection system on piston aircraft is its complexity and higher cost compared to a carburetor system. Fuel injection systems require additional components and may be more sensitive to fuel contaminants. However, they offer advantages such as improved fuel efficiency and better throttle response.
Step-by-step explanation:
One possible drawback of a fuel injection system on piston aircraft is that it can be more complex and expensive compared to a carburetor system. Fuel injection systems require additional components such as fuel pumps, injectors, and sensors, which can increase the overall cost and maintenance requirements of the aircraft.
Additionally, fuel injection systems may be more sensitive to contaminants in the fuel, which can lead to issues such as clogged injectors or fuel system malfunctions. Carburetors, on the other hand, are generally simpler in design and may be more forgiving in terms of fuel quality.
However, it is important to note that fuel injection systems offer benefits such as improved fuel efficiency, better throttle response, and more precise control over the air-fuel mixture, which can enhance the overall performance of the aircraft.
