When you think of an airplane’s wings, you probably imagine the large, curved structures on either side of the fuselage, or the aircraft’s body. Another critical component of an airplane’s wing system is located at the very back of the plane: the tailplane.

Whether it’s a traditional fixed-wing aircraft or a rotorcraft like a helicopter, every airplane has a tailplane. Let’s look at what the tailplane is and how it can impact flight.

What Is a Tailplane?

The tailplane is a small, horizontal surface at the aircraft’s rear. It’s also called the stabilizer because one of its primary functions is keeping the plane’s nose pointed in the right direction during a flight.

The tailplane works in conjunction with the vertical fin (or rudder) to provide what’s called “yaw control.” Yaw is the term for rotation around the vertical axis, which allows a pilot to point the nose of the aircraft left or right.

The tailplane is attached to the back of the fuselage behind the rear windows and cargo area. It consists of two parts: the elevator and the rudder.

The elevator is a movable, hinged section that controls the plane’s pitch (the angle at which the nose points up or down). The rudder is a vertical fin that helps the pilot steer the aircraft left or right.

The elevator and rudder allow the pilot to control the plane’s altitude and direction.

Different Types of Tailplanes

The tailplane’s size, shape, and location can vary depending on the aircraft type. For example, some smaller planes have a single vertical fin with no horizontal tailplane.

Some larger commercial airliners have a “T-tail,” or a vertical fin with the horizontal tailplane mounted on top. The T-tail configuration can provide better aerodynamic performance and stability.

How the Tailplane Works

Aerodynamic lift happens when air flows around an aircraft’s wings. This lift can cause the plane to pitch up or down, depending on the configuration of the wings. The tailplane will counter this pitch and keep the nose positioned at a safe and ideal angle for flight.

The tailplane is also responsible for keeping the aircraft’s center of gravity balanced. This step is crucial because if the center of gravity is not balanced, the aircraft will become unstable and may even enter a spin. 

To prevent this, the pilot must position the tailplane to produce an equal and opposite force to the main wings’ aerodynamic lift.

What Is a Tailplane Made Of?

The tailplane is usually metal, although some smaller aircraft may have a composite (plastic) tailplane. The elevator and rudder are also usually metal, although some planes have a composite rudder.

The tailplane also contains various control surfaces that help the pilot control the aircraft. These include the ailerons (located on the outboard edges of the wings), flaps (located on the inboard edges of the wings), and spoilers (located on the top surface of the wings).

Things To Consider When Designing a Tailplane

Several factors must go into consideration when designing a tailplane. First, the tailplane’s size and shape can factor into its design. The size of the tailplane will directly impact the amount of lift it can generate. The shape of the tailplane is also important. For example, a longer and narrower tailplane will create more lift than a shorter and wider one.

The location of the tailplane is also important. It must be able to counteract the main wings’ pitching moment. The aircraft will become unstable if it is not in the correct position.

Finally, the amount of aerodynamic drag produced by the tailplane must be consideration. The tailplane must create as little drag as possible while providing the necessary lift and stability.

Tailplanes on Airplanes vs. Helicopters

The tailplane on an airplane is very different from the tail rotor on a helicopter. The primary purpose of a helicopter’s tail rotor is to counteract the torque produced by the main rotor. This tail rotor keeps the helicopter from spinning in one direction.

The primary purpose of an airplane’s tailplane is to provide pitch control and balance the aircraft’s center of gravity. It does not play a role in counteracting torque.

How Might a Tailplane Stall?

A tailplane stall can occur when the angle of attack of the tailplane becomes too great. This stall can happen if the aircraft pitches up too sharply or encounters turbulence. When a tailplane stall occurs, the airflow around the tailplane gets disrupted, and the tailplane can no longer generate lift.

This disruption can make the aircraft difficult to control and may cause it to enter a spin. Pilots must be careful not to pitch the plane up too sharply to prevent a tailplane stall from occurring. They must also avoid flying through areas of turbulence.

A tailplane stall can have serious consequences, so you should avoid it at all costs. If you think your aircraft is stalling, immediately reduce the pitch angle and increase engine power.

The tailplane is a vital component of any aircraft. Understanding what a tailplane is and how it impacts a flight can help a pilot stay safe and learn more about flying. It helps keep the nose pitched at a safe and ideal angle for take-off, landing, and flight. It also balances the aircraft’s center of gravity, preventing instability and potential accidents.

Pilots should be aware of the dangers of tailplane stalls and avoid them. Not only can they be difficult to recover from, but they can also lead to a loss of control and serious accidents. The last thing you want is for your airplane to become unstable in the air!
