The Boeing 777X's Folding Wingtips: Why No Other Airliner Has Ever Had This

Boeing is pioneering the use of folding wingtips on its 777X aircraft, a feature previously unseen across the entire commercial airline industry. The decision stems from extensive research and development focused on reducing drag during flight operations, particularly at higher speeds. These wingtips can rotate upwards by approximately 36 degrees when cruising and fold flat against the wings’ trailing edges during takeoff and landing. This innovative design aims to improve fuel efficiency and reduce noise pollution associated with the 777X's powerful engines. Boeing anticipates that this approach will ultimately contribute to significant operational cost savings for airlines operating the new generation jetliner.
