Final answer:
To use the throttle properly before starting the fuel-injected engine in a Cessna 172, follow these steps: make sure the throttle is in the idle position, gradually increase the RPM by pushing the throttle forward, and monitor the engine instruments.
Step-by-step explanation:
Before starting the fuel-injected engine in a Cessna 172, it is important to use the throttle properly. The throttle controls the flow of fuel to the engine and helps regulate the engine's RPM (rotations per minute).
To use the throttle properly, you should follow these steps:
- Make sure the throttle is in the idle position before starting the engine. This means the throttle lever should be pulled all the way back towards you.
- Once the engine is running, gradually push the throttle forward to increase the RPM and provide more power to the engine.
- Keep an eye on the engine instruments, such as the RPM gauge and the engine temperature, to ensure the engine is running smoothly and within the desired parameters.
By using the throttle properly, you can start the fuel-injected engine in a Cessna 172 effectively.
