The Boeing 737 is a widely recognized and successful aircraft that has been a staple in the aviation industry for several decades. One of the key features of this aircraft is the overwing area, often referred to as OVWG. The overwing section plays a crucial role in the overall design and functionality of the Boeing 737. In this article, we will delve into the specifics of the overwing on the Boeing 737, exploring its purpose, components, and significance in the aircraft’s operation.

The Importance of the Overwing on Boeing 737
To understand the importance of the overwing area on the Boeing 737, it is essential to grasp its primary function. The overwing section is responsible for various critical functions, including fuel storage, emergency exits, and wing structure integrity. Let’s take a closer look at each of these components and their significance.
The Role of Overwing in Fuel Storage
In the Boeing 737, the overwing area serves as a fuel storage compartment. The wings of the aircraft contain fuel tanks, which are typically divided into several compartments to enhance safety. Fuel storage in the overwing section provides several advantages in terms of weight distribution and risk mitigation.
By positioning fuel tanks in the overwing area, the weight of the fuel is closer to the center of gravity of the aircraft. This distribution of weight helps maintain stability during flight and reduces the risk of the aircraft becoming unbalanced. Additionally, in the event of a fuel leak or fire, the overwing fuel storage allows for better containment, minimizing potential damage to other critical components of the aircraft.
Emergency Exits and Evacuation Procedures
Another vital aspect of the overwing on the Boeing 737 is its role in providing emergency exits. In the event of an emergency or evacuation, passengers can use the overwing exits as alternative escape routes. These exits are designed with specific evacuation procedures in mind to ensure a safe and efficient evacuation process.
The positioning of overwing exits plays a crucial role in evacuating passengers from the aircraft quickly. They are strategically placed to minimize the distance between the exits and the ground, enabling passengers to safely jump onto inflatable slide rafts or escape through emergency doors. The overwing exits are equipped with evacuation slides or other means of egress, allowing passengers to exit the aircraft rapidly and efficiently.
Contributing to Wing Structure Integrity
In addition to its role in fuel storage and emergency exits, the overwing area also contributes to the overall strength and integrity of the Boeing 737’s wing structure. The wing of an aircraft must withstand various forces, including aerodynamic forces, maneuvering loads, and external factors such as turbulence or gusts of wind.
The overwing area incorporates structural elements, such as ribs and spars, which provide essential support and reinforcement to the wing structure. These components help distribute the loads evenly throughout the wing, ensuring its structural integrity during flight and any anticipated stresses. The overwing section also plays a role in maintaining the correct wing shape and preventing excessive bending or flexing that could compromise the aircraft’s performance.
Conclusion
The overwing section of the Boeing 737 is a critical component that contributes to the overall functionality, safety, and performance of the aircraft. Its role in fuel storage, emergency exits, and wing structure integrity highlights its significance in ensuring a balanced and secure flight experience. By understanding the importance of the overwing on the Boeing 737, we gain a deeper appreciation for the meticulous design and engineering that goes into creating one of the most renowned aircraft in the world.
