Mastering the Chandelle Maneuver: A Guide to Maximum Performance Turns

By Jason Miller

Introduction

In this blog post, we will delve into the world of commercial maneuvers and focus on one specific technique called the Chandelle. If you've seen our previous video on lazy eights, you'll know that these maneuvers are all about leveraging the secondary effects of controls to achieve precise and effective turns. The Chandelle, in particular, is a maximum performance 180-degree climbing turn that requires careful management of these effects. Join us as we explore the ins and outs of this maneuver, providing you with all the information you need to master it.

Understanding the Chandelle

The Chandelle is performed in the following manner: First, you select a specific reference point at the 90-degree position. Let's imagine we're turning to the left. You would pick something distinct, such as a rivet line, and focus on it. Next, you initiate a 30-degree bank by rolling the aircraft and apply full power and right rudder. As you do this, slowly pitch up while maintaining a constant bank angle until the nose reaches the 90-degree reference point. At this moment, you transition to the second half of the maneuver. You maintain the maximum pitch up achieved and gradually adjust the bank angle so that you end up with your right wing on the same reference point.

It's important to recall what we learned in the lazy eights video. When an airplane is banking and slowing down, it tends to overbank. The Chandelle maneuver is all about managing and counteracting these effects. As the aircraft slows down, you will need to increase the opposite aileron to maintain the 30-degree bank. Additionally, you will notice the need for increased pressure on the right rudder. This is due to the left-turning tendencies caused by the combination of slowing down and pitching up. By the time you complete the maneuver, your right wing will be off the 90-degree reference point, and you will find yourself relying heavily on the rudder to maintain control.

Perfecting the Chandelle

Performing a flawless Chandelle requires attention to detail and a deep understanding of the aircraft's behavior during the maneuver. Let's break down the key steps and considerations to keep in mind:

Select a clear reference point at the 90-degree position.
Roll into a 30-degree bank, simultaneously applying full power and right rudder.
Pitch up slowly while maintaining the bank angle until the nose reaches the reference point.
Hold the achieved maximum pitch up and gradually adjust the bank angle until the right wing is on the reference point.
Manage the overbanking tendency by increasing opposite aileron pressure.
Counteract the left-turning tendencies by increasing pressure on the right rudder.
Be aware of the need for continuous back pressure on the control yoke to maintain the same pitch attitude as the aircraft slows down.

Implementing these steps effectively will result in a smooth and controlled Chandelle maneuver. Mastery of this technique will impress your peers and demonstrate your ability to handle maximum performance turns accurately.

The Chandelle in Practice

Now that we've covered the theory behind the Chandelle maneuver, let's see it in action. In the accompanying video, we demonstrate the Chandelle and provide valuable insights into its execution. Our pilot, Serge, graciously allows us to share his flight training experience with you. While we don't have a wing camera for this particular video, we do have a forward camera and a camera focused on the cockpit, giving you a comprehensive view of the maneuver.

Before attempting the Chandelle, it's essential to establish a stable flight condition. In the video, we start at 4,500 feet and let the aircraft stabilize at around 90 knots. Throughout the demonstration, we maintain a watchful eye on the reference point and carefully manage the aircraft's behavior.

As you watch the video, pay close attention to the pilot's actions and the sight picture. Notice how the pilot initiates the 30-degree bank, applies full power and right rudder, and gradually pitches up while maintaining the bank angle. The goal is to reach the maximum pitch up when the nose aligns with the 90-degree reference point. After this point, the pilot skillfully adjusts the bank angle to position the right wing on the reference point.

While executing the Chandelle, it's crucial to keep the aircraft's behavior in check. For instance, the overbanking tendency can be managed by applying the appropriate opposite aileron pressure. Additionally, as the aircraft slows down and pitches up, you may notice a left-turning tendency. This requires increased pressure on the right rudder to maintain control.

Avoiding Pitfalls: Stalling and Sight Picture

Stalling is a concern during the Chandelle maneuver. However, with proper technique, the risk of stalling is minimal. It's important to note that in all our years of experience, we have never accidentally stalled an aircraft during a Chandelle. One key point to remember is that the stall horn may sound during the maneuver, but it should not cause alarm. Releasing a small amount of pressure will prevent a stall. By continuously increasing back pressure, you can maintain the desired maximum pitch up while avoiding a stall.

Another aspect to consider is the sight picture during the Chandelle. It's essential to familiarize yourself with the visual cues that indicate you're holding the maximum pitch up correctly. In the video, you'll notice how the pilot adjusts the pitch until the reference point is aligned with the nose. By memorizing this sight picture, you can ensure consistent and accurate execution of the maneuver.

Conclusion

The Chandelle maneuver offers pilots a thrilling opportunity to showcase their skills in executing maximum performance turns. By understanding the underlying principles of the maneuver and carefully managing the secondary effects of controls, pilots can achieve precise and controlled turns. Remember, the key to a successful Chandelle is selecting a clear reference point, maintaining the appropriate bank angle, and managing the overbanking and left-turning tendencies. Through practice and dedication, you can master this maneuver and demonstrate your proficiency in the skies.
