What Does a Pilot Steer With: A Comprehensive Guide
Air travel is a marvel of modern engineering, and the pilot's role in steering an aircraft is a fascinating aspect of aviation. Pilots use different controls depending on the aircraft type. From the Airbus plane's side stick to the traditional yoke and the unique ram horn, each plays a crucial role in the safe and efficient operation of an aircraft. In this article, we'll explore the various controls pilots use and what they are called, backed by detailed descriptions and visual aids.
Introduction to Aircraft Steering Controls
When someone asks, "What does a pilot steer with?" the answer often depends on the aircraft type. In modern passenger aircraft like those manufactured by Airbus, pilots use a side stick. This control is part of the fly-by-wire system, where inputs are transmitted electronically to the aircraft's computer systems, which then issue flight control instructions to the aircraft's control surfaces. This is a significant advancement over traditional mechanical systems and plays a vital role in modern aviation safety and efficiency.
Airbus Aircraft: Side Stick
The side stick is a control column that is positioned between the pilot and the co-pilot. It allows pilots to control the aircraft's pitch, roll, and bank movements. When the side stick is moved, it sends signals to the aircraft's computer systems. These signals are then translated into corresponding actions by the aircraft's control surfaces, such as ailerons, elevators, and rudder.
Example of a Side Stick (Airbus A320):
Non-Airbus Aircraft: Yokes and Ram Horns
Most non-Airbus aircraft types, such as the Boeing 737 or Embraer regional jets, use a yoke. The yoke functions similarly to a steering wheel but is designed for precise control during flight. Just like the Airbus side stick, moving the yoke triggers signals to the aircraft's control surfaces. However, unlike the Airbus system, non-Airbus yokes often use a combination of mechanical and hydraulic systems in addition to electrical signals for more precise control.
Example of a Yoke:
In addition to Airbus and Boeing, some aircraft manufacturers like Embraer and Russian manufacturers use a unique control called the ram horn. This control system is not as well-known as the side stick or yoke, but it is just as important for handling the aircraft. The ram horn is a control yoke with two large, horn-shaped projections on either side. These projections provide additional control authority and feel, making it easier for pilots to manipulate the aircraft's flight path.

Historical Insights and Advancements
The evolution of aircraft steering controls from purely mechanical to sophisticated fly-by-wire systems has significantly improved safety and efficiency. Early aircraft had manual control columns and mechanical linkages to the control surfaces. However, as technology advanced, these systems were replaced with more sophisticated controls to enhance pilot workload management and reduce human error.
Traditional Aircraft Control Columns:
The transition from manual to fly-by-wire systems has been gradual, but it has brought about significant improvements in aircraft maneuverability and safety. For example, the Airbus A320, introduced in the 1980s, was the first commercial aircraft to achieve wide-scale adoption of fly-by-wire technology.
Conclusion
In summary, the controls that a pilot uses to steer an aircraft vary widely depending on the aircraft type. Whether it's an Airbus plane's side stick, a yoke, or the unique ram horn, each control plays a critical role in the safe and efficient operation of the aircraft. Understanding these controls is not only important for pilots but also for aviation enthusiasts and anyone interested in the fascinating world of modern aviation.
