Be Gentle with it
As pilots, we all know the importance of being careful and precise with our aircraft controls. One area that often requires extra attention is the throttle.
The throttle directly affects the aircraft's speed and performance since it regulates how much power the engine outputs. It's critical to keep in mind that rapid or forceful throttle motions can harm the engine and reduce its lifespan.
When adjusting the throttle, it is important to do so smoothly and gradually. Rapid changes in power can cause stress on the engine and can lead to malfunctions or even engine failure. Instead, make small adjustments as needed and pay close attention to the engine's performance.
In some aircraft, this is far more important than in others. For those of us who have ever flown an aircraft with a Stromberg carburetor understand. Stromberg carbs have an automatic mixture and are known to cut out the engine when a pilot gets too punchy with the throttle. Doing this at low altitudes, such as during a go-around, can be interesting.
Our aircraft piston engines are designed and built differently than our automotive engines. While it is common to see cars “floor it” and not have an issue, this has a lot to do with their liquid-cooled design. Conversely, with our aircraft engines’ air-cooled design, continually “firewalling” the throttle in your aircraft will eventually cause you some trouble.
Being mindful of your inputs reduces the stress on your aircraft. While there are concerns about “babying” your aircraft, being too aggressive is a bigger concern. Think of it like exercise, you want to exercise your aircraft regularly, just like your body. Too little is not effective and can cause problems, but also going to the gym and performing full out can cause injury. You want to find the balance of regular exercise at a good pace. For example, a good rule of thumb is to fly once a week and fly for at least an hour to burn off moisture in your engine.
By being considerate with the throttle and properly maintaining the engine, we can ensure that our aircraft performs at its best for years to come.
Fly Safe!
