In light of the recent turbulence incidents involving Singapore Airlines Flight SQ321 and Qatar Flight QR017, I propose a novel solution to enhance flight stability. By retrofitting civilian aircraft with anhedral wings, we can significantly mitigate the effects of turbulence. This wing design is adept at smoothing the ride due to its ability to distribute the aircraft’s weight effectively beneath the wing structure.
However, it’s important to consider the trade-offs of this design. For instance, the anhedral wing configuration presents challenges during emergency water landings, or “ditching.” A poignant example is the incident of US Airways Flight 1549 on January 5th, 2009. After a bird strike disabled the engines shortly after departure from LaGuardia Airport, the aircraft was successfully ditched in the Hudson River, and all passengers and crew were saved. In the aftermath, the passengers’ use of the dihedral wings for evacuation underscored the critical role these wings play in ensuring safety during unforeseen events.
Traditionally, dihedral wings have been the standard for wide-body commercial aircraft, such as those manufactured by Airbus and Boeing, due to their contribution to passive stability and safety. Conversely, anhedral wings are less common and typically found on select narrow-body passenger aircraft and large cargo planes, where they enhance stability and maneuverability.
