Which aircraft does not utilize the GBU support strap?

• A. 747, 777
• B. 737, 787
• C. A320, A330
• D. Bombardier Q400

Answer: (B)

The correct answer identifies the 737 and 787 as the aircraft that do not utilize the GBU (Gimbal Beams Unit) support strap. The GBU support strap is a component typically used in larger aircraft to assist with the secure mounting of certain equipment, ensuring stability during operations. In contrast, the 737, being a narrow-body aircraft, generally employs a different mounting approach compared to larger airliners such as the 747 or 777, which have the space and structural considerations that necessitate the use of the GBU support strap. The 787, while larger than the 737, utilizes advanced materials and construction methods that differ from those needed for traditional GBU support. This knowledge of aircraft design and operational practices highlights the differences in how various aircraft types handle equipment mounting. Consequently, the absence of the GBU support strap on the 737 and 787 indicates their respective engineering approaches to maintain performance and safety without this specific support mechanism.
