What is ATT on Boeing 737? (Attitude)

The Boeing 737 is one of the most popular and widely used aircraft models in the world. It has a rich history and has evolved over the years to become a highly efficient and reliable aircraft. One term that often comes up in discussions about the Boeing 737 is “attitude.” Attitude, or ATT, plays a crucial role in the safe and efficient operation of the aircraft. In this article, we will explore what attitude means in the context of the Boeing 737 and its significance in flight operations.

Understanding Attitude on the Boeing 737

In aviation, attitude refers to the orientation of an aircraft in relation to the horizon. It encompasses the pitch, roll, and yaw of the aircraft. The Boeing 737 relies on a system known as the Attitude Reference System (ARS) to measure and maintain its attitude during flight. The ARS consists of multiple sensors and gyroscopes that provide continuous inputs to the flight control system, ensuring the aircraft remains stable and responsive to pilot commands.

The attitude of the Boeing 737 is a critical parameter for several reasons. Firstly, it directly affects the aircraft’s performance and maneuverability. By adjusting the attitude, pilots can control the climb, descent, and banking of the aircraft, allowing them to navigate through various flight conditions with precision. Additionally, the attitude plays a vital role in maintaining a stable flight path and ensuring a comfortable experience for passengers. By keeping the aircraft level and stable, pilots can minimize turbulence and create a smooth ride.

Significance of Attitude in Flight Operations

The accurate measurement and maintenance of attitude are crucial for safe flight operations. The attitude indicators in the cockpit provide pilots with real-time information about the orientation of the aircraft. They are vital during instrument flight, where pilots rely on the instruments rather than visual cues to navigate through clouds or low visibility conditions. By monitoring the attitude indicators, pilots can ensure that the aircraft is following the desired flight path and making the necessary adjustments if deviations occur.

Attitude also plays a critical role during takeoff and landing, which are considered to be the most critical phases of flight. During takeoff, the aircraft’s attitude needs to be carefully controlled to ensure a smooth transition from ground to air. The correct pitch and roll angles must be maintained to generate enough lift and prevent any potential hazards. Similarly, during landing, the aircraft’s attitude must be carefully managed to ensure a safe and controlled touchdown.

The Boeing 737 is equipped with advanced avionics systems that continuously monitor and maintain attitude. These systems are designed to provide pilots with accurate and reliable information, improving situational awareness and enhancing safety. They also incorporate built-in redundancy, ensuring that even in the event of a failure in one system, the aircraft remains controllable and safe.

The Future of Attitude on the Boeing 737

The aviation industry is constantly evolving, and technology advancements are shaping the future of aircraft systems. In the case of the Boeing 737, future iterations of the aircraft are likely to incorporate more advanced attitude measurement and control systems. These may include enhanced sensors, improved data processing capabilities, and even augmented reality displays in the cockpit to provide pilots with a more intuitive understanding of the aircraft’s attitude.

As the industry continues to prioritize safety and efficiency, the role of attitude in flight operations will remain of utmost importance. By continually improving the accuracy, reliability, and redundancy of attitude systems, manufacturers like Boeing can enhance the overall performance and safety of their aircraft models.


In conclusion, attitude plays a vital role in the operation of the Boeing 737 aircraft. It refers to the orientation of the aircraft in relation to the horizon and affects its performance, maneuverability, and stability. The accurate measurement and maintenance of attitude are crucial for safe flight operations, especially during critical phases like takeoff and landing. With advances in technology, the future of attitude systems on the Boeing 737 looks promising, with increased accuracy and enhanced pilot interfaces. By continuously improving these systems, Boeing ensures that their aircraft models remain at the forefront of aviation excellence.
