A General Introduction to the Boeing 737NG Flight Controls

Flying on a Boeing 737 Next Generation (NG) aircraft can be an exhilarating experience, especially if you have a vested interest in how these marvels of modern engineering operate. One aspect that fascinates many aviation enthusiasts is the intricate system of flight controls that allow these aircraft to soar through the skies with precision and grace. In this blog, we will take a closer look at the flight controls of the 737NG series, exploring key components such as ailerons, speed brakes, avionics, and other essential mechanisms that ensure smooth and safe flight.

One of the main elements of the Boeing 737NG’s flight control system is the ailerons that are located on the trailing edges of the wings, which are hinged surfaces used to manage roll during flight. With the use of a Power Control Unit (PCU), pilots can easily adjust the deflection of ailerons directly or indirectly, the PCU serving as the interface between the pilot’s commands and flight surfaces. While ailerons are a major aspect of adjusting roll, they are used in conjunction with flight spoilers on the Boeing 737NG.

In addition, the 737NG series is equipped with a sophisticated speed brake system. Speed brakes, also known as spoilers, play a vital role in controlling the aircraft's speed and descent rate. These deployable panels are located on the wings and can be extended into the airflow to increase drag, effectively slowing down the aircraft. Pilots can activate the speed brakes manually or configure them to deploy automatically during certain phases of flight, such as landing or during rapid descents. By adjusting the position of the speed brakes, pilots can regulate the aircraft's descent rate and ensure a smooth and controlled approach to the runway.

Another essential aspect of 737NG flight controls is a hydraulic system. Hydraulic power is used to actuate various control surfaces, including the ailerons, elevators, and rudder. These surfaces are responsible for controlling the aircraft's roll, pitch, and yaw movements, respectively. By applying hydraulic pressure to these surfaces, pilots can maneuver the aircraft with precision and respond to aerodynamic forces encountered during flight. The 737NG series features a redundant hydraulic system to ensure continued operation in the event of a system failure, enhancing safety and reliability.

In addition to traditional flight controls, the 737NG series is also equipped with advanced avionics systems that enhance situational awareness and assist pilots in managing the aircraft. These systems include autopilot, autothrottle, and flight management computers, which work in conjunction with the flight controls to automate various tasks and reduce pilot workload. Autopilot, for example, can be engaged to maintain a predetermined heading, altitude, or airspeed, which allows pilots to focus on other aspects of flight. Similarly, the autothrottle system can automatically adjust engine thrust to maintain a desired speed, further enhancing flight efficiency and comfort.

Overall, the flight controls of the 737NG are exemplary of the ingenuity and innovation of modern aviation technology. From ailerons to the speed brake system and beyond, each component plays a crucial role in ensuring the aircraft's safe and efficient operation. Whether you are a seasoned pilot or an aviation enthusiast, understanding how these systems work can deepen your appreciation for the marvels of flight.
