What is ACT on Boeing 737? (Active)

The Boeing 737 aircraft is one of the most popular and widely used aircraft models in the world. With its long history and continuous advancements, the Boeing 737 has undergone various upgrades and modifications to enhance its performance, safety, and efficiency. One important feature that contributes to the effectiveness of the Boeing 737 is its active systems and technologies, often referred to as ACT (Active). In this article, we will delve into the active features and technologies present in the Boeing 737, highlighting their significance and impact on the aircraft’s operations.

Active Systems in Boeing 737

The active systems in the Boeing 737 play a crucial role in ensuring the aircraft operates efficiently and safely. These systems are designed to actively monitor and control various aspects of the aircraft, providing real-time information and adjustments to pilots. Let’s explore some of the key active systems present in the Boeing 737.

Fly-by-Wire System

The Fly-by-Wire (FBW) system is one of the most significant active systems in the Boeing 737. This system replaces traditional manual flight controls with an electronic interface, where the pilot’s inputs are transmitted to the control surfaces by electrical signals. The FBW system offers numerous benefits, including enhanced control precision, reduced weight, improved fuel efficiency, and increased safety.

The FBW system on the Boeing 737 incorporates multiple redundant computers, sensors, and actuators to ensure reliability and fault tolerance. It constantly monitors the aircraft’s flight parameters and makes necessary adjustments to maintain stability and respond to pilot commands accurately. By actively managing the flight controls, the FBW system contributes to the overall safety and maneuverability of the aircraft.

Flight Management System (FMS)

The Flight Management System (FMS) is another crucial active system found in the Boeing 737. The FMS integrates various components, including navigation systems, autopilot, and control systems, to assist pilots in flight planning, navigation, and guidance. It uses advanced algorithms to optimize flight paths, calculate fuel consumption, and manage aircraft performance.

The FMS on the Boeing 737 actively communicates with the aircraft’s avionics and sensors to collect data, perform calculations, and generate accurate navigational and performance information. It allows pilots to input their desired routes, altitude, and other parameters, following which the FMS automatically calculates the most efficient and safe flight plan. This active system significantly reduces the workload on pilots, enhances flight efficiency, and improves the accuracy of navigation.

Benefits of Active Systems on Boeing 737

The active systems present in the Boeing 737 offer several advantages that contribute to the overall performance and safety of the aircraft. Let’s explore some of these benefits in detail.

Enhanced Safety and Reliability

Active systems, such as the Fly-by-Wire system, enhance the safety and reliability of the Boeing 737. By eliminating the physical connection between the control surfaces and cockpit controls, the FBW system reduces the risk of control surface damage caused by excessive pilot inputs or external factors. Additionally, the redundant design of active systems ensures that even in the event of a failure, alternative mechanisms and backup systems are available to maintain control and functionality.

Improved Fuel Efficiency

Active systems, such as the Flight Management System, contribute to improved fuel efficiency in the Boeing 737. The FMS actively monitors the aircraft’s performance, weather conditions, and fuel consumption, enabling pilots to optimize flight plans and make fuel-saving decisions. By constantly analyzing data and suggesting the most efficient routes and altitudes, the FMS helps reduce fuel consumption, leading to cost savings for airlines and a lower environmental impact.

The Future of Active Systems in Boeing 737

The active systems in the Boeing 737 have already revolutionized the aviation industry, providing enhanced safety, efficiency, and reliability. However, the future holds further advancements and improvements in active technologies for this iconic aircraft.

One area of development is the integration of more advanced artificial intelligence (AI) and automation systems. These systems can continuously analyze vast amounts of data in real-time, enabling more accurate decision-making and proactive responses. By incorporating AI, the active systems in future Boeing 737 models can further improve safety, optimize performance, and enhance the overall flying experience.

It is important to note that active systems should always work in conjunction with the skills and expertise of pilots. They are designed to assist and enhance, but not replace, human control and decision-making. The combination of advanced active systems and well-trained pilots will continue to drive the success and reliability of the Boeing 737 in the years to come.


The active systems in the Boeing 737, such as the Fly-by-Wire system and Flight Management System, are integral to the aircraft’s performance, safety, and efficiency. These advanced technologies actively monitor and control various aspects of the aircraft, providing real-time information to pilots and optimizing flight parameters. With their numerous benefits, including enhanced safety, improved fuel efficiency, and precise control, the active systems in the Boeing 737 continue to shape the future of aviation.
