An aileron plane plays a crucial role in flight dynamics and control. Every pilot should understand the power behind ailerons, as they influence various aspects of a jet’s performance. From creating adverse yaw—countered by differential or frise ailerons—to inducing drag and affecting the angle of attack, ailerons have a significant impact on flight safety and maneuverability.
Whether you’re a seasoned pilot or just getting started, understanding how aileron planes work is essential for mastering the dynamics of flight control.
In this article, we’ll explore how aileron planes affect the way an aircraft turns, rolls, and handles in the air.
How an Aileron Plane Affects Flight Dynamics and Control
Ailerons are a type of control surface located on a plane’s wings, near the wingtips. They are hinged components that can be maneuvered up or down based on the conditions of the flight. Simply put, ailerons alter the airflow over the wing and influence its lift.
But they do so much more than just help the pilot turn the jet.

Ailerons Create Adverse Yaw
An adverse yaw is the plane’s tendency to go in the opposite direction when it is turning. Pilots use the control wheel to manage aileron deflections, which can influence the aircraft’s yaw behavior. For instance, if you are rolling to the left, the plane may yaw to the right. This is a common occurrence in aviation and is something that pilots must know how to address. Using the ailerons appropriately will impact this yaw.
In the example above, let’s say you are mid-flight and need to roll your jet to the left. In this situation, the left aileron will be in an upward position. This will reduce the lift and drag – especially when compared to the right aileron that has remained in the lowered position.
Because the aileron on the right wing remains in a downward, lowered position, it has greater draw and lift, ultimately causing the plane to yaw in the opposite direction of your turn.
Differential Ailerons Can Counter Adverse Yaw
To get your plane to go in the direction you are turning and avoid (or reduce) an adverse yaw, the ailerons can be differentially operated. Pilots manipulate the control stick to adjust aileron deflection, which helps in managing the aircraft’s roll and reducing adverse yaw. In other words, the ailerons can be moved in different directions at different rates. This gives the pilot much more control over the roll rate.
Need a clearer picture of differential ailerons?
Imagine having one aileron raised to a greater degree than the other wing’s aileron is lowered. This will lead to additional drag on the upward aileron with less draw or lift on the other. The result will be easier to turn with less adverse yaw.
Frise Ailerons Can Be Used to Counter Adverse Yaw
Frise ailerons are designed to address adverse yaw. Frise ailerons are mounted on the trailing edge of the wings, where they can effectively manage airflow and counteract adverse yaw. They differ from traditional types that simply go up or down on their hinged axis. An aileron plane with these for control will be easier to maneuver and experience less adverse yaw when turning.
Here’s what sets frise ailerons apart.
Frise ailerons are designed to increase drag on the lowered wing by extending further. Then, as the aileron is lifted upward, it protrudes a little downward underneath the wing at the same time. This can impact the airflow and counteract the adverse yaw.
Ailerons Used During a Stall Can Cause a Sudden Roll
When flying an aileron plane, it is important to note that you have control over your ailerons on each wingtip — and can control your angle of attack (AOA). Yaw movement during a stall occurs around the vertical axis, influenced by the roll input through ailerons. If the angle of attack is exceeded, the entire wing can stall, leading to significant control issues and potential spins.
Lowering the aileron can cause the wing to fly at a higher AOA. And, of course, raising the aileron can cause the wing to fly at a lower AOA. However, if you lower the aileron too much, you can stall the wing and cause the airplane to make a sudden roll in that direction.
Induce Drag with Ailerons on the Trailing Edge
Speaking of your AOA, it is worth noting that the lowered aileron doesn’t just lead to sudden rolls, but it can also cause an increase in lift and drag, as well. When the aileron is lowered, the descending wing experiences reduced lift and drag, which can influence the aircraft’s maneuverability. This is referred to as induced drag. Why?
While you may encounter drag in many situations when piloting an aircraft, it is referred to as induced because it is caused by lowering the aileron. Its hinged position creates the drag.
Neutralize Ailerons Can Slow a Spin
If your plane is spinning, each wing has stalled. The low wing has a higher AOA than the high wing. The ailerons control the aircraft’s rolling motion around its longitudinal axis, which is crucial for maintaining stability during a spin. By adjusting the ailerons, you can help them to neutralize, creating the same AOA for each wing. This will slow the roll.
As it begins to level out, it may start spinning in the opposite direction and the ailerons will need to be adjusted once again.

You have always wanted to see the power of aerodynamics in flight, but you can’t experience it when taking a commercial or chartered passenger flight. Modern aircraft used in airshows often feature advanced control mechanisms like spoilers and yaw dampers to enhance performance and stability. So, where can you see the aileron roll, the slow roll, the barrel roll, and many other performance-worthy airshow tricks?
The pilots are highly skilled and offer an amazing performance every time.
Plan on being a spectator. Or, you can sign up early to volunteer, be a vendor, or be a sponsor of the event that touches so many lives each year!
Conclusion
Taking advantage of ailerons and how they can impact the aerodynamics of a plane can be highly beneficial when performing at an airshow. Ailerons, along with other control surfaces like flaps and spoilers, play a crucial role in the aircraft’s maneuverability and stability.
But these facts about ailerons aren’t just for show — they can mean the difference between a safe flight and the unthinkable. Understanding how they work and how to control them is crucial before ever taking flight in an aileron plane.
