Commercial Pilot License (CPL) Practice Exam

In a fuel-injected system, throttle response is improved due to the direct control of fuel delivery to the engine based on the demand from the throttle position. Unlike carbureted systems, which rely on air flow to create a venturi effect that draws fuel into the airstream, fuel injection allows for more precise control over the fuel mixture delivered to the engine. This responsiveness contributes to smoother acceleration and better overall engine performance, allowing the pilot to more effectively manage power output and engine efficiency.

The improved throttle response is particularly advantageous during critical phases of flight, such as takeoff and climb, where rapid changes in power are often required. Enhanced throttle response also helps eliminate the lag that can sometimes occur in carbureted systems, making the aircraft more predictable and easier to handle.

Other aspects like evaporative icing and fuel vaporization are influenced by various factors specific to the system design and environmental conditions, but they do not represent the primary advantage of fuel injection systems compared to traditional carbureted systems. Engine temperature regulation, while important, is also managed through other means in an aircraft and does not highlight the unique benefits of fuel injection.
