Navigating an Aircraft After Landing: The Role of the Tiller and Rudder

The transition from flight to taxiing is a critical phase in a pilot's responsibilities. Understanding the roles of the tiller and rudder in maneuvering an aircraft after landing is crucial for effective and safe ground operations. This article delves into the specifics of these control mechanisms and answers the question: do pilots use the rudder or tiller to exit the runway after landing?

Role of the Tiller and Rudder in Ground Operations

Typically, pilots use the tiller to steer the aircraft during ground operations, including when exiting the runway after landing. A tiller is a small wheel located on the captain's side of the cockpit, offering precise control over the nose wheel, particularly at low speeds.

By contrast, the rudder is primarily used for controlling yaw during flight and for directional control during takeoff and landing phases. It is not utilized for taxiing on the ground. After an aircraft touches down, the pilot engages the tiller to navigate the aircraft off the runway and through taxiways.

Factors Influencing Control Mechanism Usage

The choice between using the tiller or rudder to exit the runway can vary depending on the aircraft type:

Some Aircraft Use Rudder at All Speeds: Certain aircraft are designed to use the rudder for nose wheel steering at all speeds. This can offer more efficient and precise control. However, switching between control methods, such as changing the amount of steering change for a certain amount of rudder pedal movement, is also necessary for some models. Engagement and Disengagement: Some aircraft have a feature where the nose wheel steering can be engaged and disengaged using a button on the stick or wheel. This allows pilots to switch control methods more fluidly as conditions change. Type of Aircraft: The tiller is typically found on the captain's side, offering greater control in tight spaces. The rudder, located on the control pedals, provides less maneuverability but more range of motion. For example, certain aircraft can offer 5 degrees of control with the rudder and up to 30 degrees with the tiller.

Specific Aircraft Control Mechanisms

The use of the tiller or rudder can vary based on the specific aircraft in question:

Tiller: The tiller is more common on smaller aircraft and is primarily used for tight turns and precise steering. It offers 30 degrees of control, making it ideal for navigating tight taxiways. Rudder Pedals: Rudder pedals serve dual purposes. While they control the rudder during flight, when the landing gear is down, they also control the nose wheel steering, ensuring smooth and precise maneuvering of the entire aircraft.

Conclusion

To summarize, the choice of using the tiller or rudder to exit the runway after landing depends on the aircraft type and the specific design features of the control systems. A tiller offers precise control for tight turns, while rudder pedals provide more general movement control. Understanding these differences is key to ensuring safe and efficient ground operations in aviation.

For pilots, it is imperative to familiarize themselves with the specific control mechanisms of their aircraft to perform effective and smooth ground operations. By understanding the role of the tiller and rudder, pilots can navigate complex taxi routes and safely maneuver their aircraft from the runway to the terminal.
