What is AUTO on Boeing 737? (Automatic)

When it comes to aircraft, automation plays a crucial role in ensuring safe and efficient operations. The Boeing 737, a popular commercial airliner, is equipped with a range of automatic features designed to assist pilots and streamline flight processes. In this article, we will delve into the world of automatic systems on the Boeing 737, and specifically focus on the AUTO functions that contribute to the aircraft’s performance and overall flight experience.

The AUTO Pilot on Boeing 737: Enhancing Flight Control

The AUTO Pilot, also known as the Autopilot system, is a vital component of the Boeing 737’s automatic features. It assists in maintaining the desired altitude, heading, and airspeed during flight, reducing the workload on pilots and ensuring precise control. The Autopilot system utilizes various sensors and inputs to continuously monitor the aircraft’s position, movement, and environmental conditions. It then makes necessary adjustments to keep the aircraft on the intended flight path.

One of the key advantages of the Boeing 737’s AUTO Pilot system is its ability to fly pre-programmed routes. Pilots can input the desired waypoints, headings, and altitudes into the Flight Management System (FMS), and the Autopilot will automatically guide the aircraft along the designated route. This feature not only enhances safety by reducing the risk of navigation errors but also improves fuel efficiency by optimizing the flight path.

Moreover, the Boeing 737 AUTO Pilot system has the capability to perform auto landings, assisting pilots during challenging weather conditions or low visibility situations. With the guidance of ground-based instruments and the Autopilot system, the aircraft can safely touchdown and come to a stop on the runway. This feature is particularly valuable in airports where fog, heavy rain, or snow may hinder visual navigation.

AUTO Thrust Management: Optimization of Engine Performance

Another significant automatic system on the Boeing 737 is the AUTO Thrust Management. The AUTO Thrust Management system helps pilots optimize engine performance, ensuring the aircraft operates within defined limits while maximizing fuel efficiency.

The AUTO Thrust Management system takes inputs from various sources such as airspeed sensors, thrust levers position, and altitude sensors. Based on these inputs, it automatically adjusts the thrust of the engines to maintain the desired speed and meet specific performance criteria. This feature proves vital during climb, descent, and cruise phases of flight, assisting pilots in achieving the optimal balance between speed, efficiency, and engine health.

Additionally, the AUTO Thrust Management system on the Boeing 737 enables pilots to engage the auto thrust mode during the takeoff roll, ensuring a smooth and controlled acceleration. By maintaining the correct power settings, this feature helps pilots focus on other critical aspects of the flight, such as monitoring the aircraft’s systems and executing necessary checklists.

The AUTO Brakes: Enhancing Safety and Efficiency

The AUTO Brakes system is yet another valuable automatic feature on the Boeing 737, contributing to both safety and efficiency. This system assists pilots in controlling and modulating the braking action during landing and deceleration.

The AUTO Brakes system operates by utilizing inputs from various sensors, such as wheel speed sensors and brake pressure sensors. These inputs allow the system to modulate the brake pressure and apply the appropriate amount of braking force, ensuring efficient deceleration and preventing excessive wear on the brakes.

One of the notable features of the AUTO Brakes system is its ability to calculate the landing distance required based on aircraft weight, runway conditions, and other factors. This feature, known as autobrake, aids pilots in determining the appropriate level of brake pressure needed for a safe landing and rollout. By automatically adjusting the braking force, the system assists in reducing the risk of runway overshoot or wheel lockup.

Moreover, the AUTO Brakes system also contributes to optimizing fuel efficiency. By ensuring smooth deceleration and minimizing unnecessary brake applications, it allows for more controlled taxiing and reduces wear on the brakes, resulting in lower maintenance costs.

In conclusion, the Boeing 737 aircraft incorporates several automatic features that significantly enhance its performance, safety, and efficiency. The AUTO Pilot system assists in maintaining precise control and enables pre-programmed route navigation and auto landings. The AUTO Thrust Management system optimizes engine performance and fuel efficiency, while the AUTO Brakes system enhances safety and contributes to efficient deceleration. These automatic features work in harmony to support pilots in their operations, providing a reliable and advanced flight experience aboard the Boeing 737.
