Could Folding Wings Solve Aviation’s Wingspan Problem?

Aircraft wings are getting a second look.

For years, the basic challenge in commercial aviation has been clear. Airlines want aircraft that burn less fuel, produce lower emissions and operate more efficiently over long distances. One of the most effective ways to improve that efficiency is to use longer, slimmer wings.

The problem is that airports were not built for unlimited wingspan.

That is why folding aircraft wings are back in the conversation. They offer a way to give aircraft more aerodynamic efficiency in the air without making them too wide for existing gates, taxiways and ground operations.
