The Federal Aviation Administration has approved for commercial use the folding composite wingtips that will be installed on the upcoming Boeing 777-X program.
The two variants, the -8 and -9, can now use the wingtips without any form of restrictions commercially.
The only condition that the FAA subjected to Boeing was that the aircraft must have multiple automatic warning systems which will let pilots know whether the wingtips are fully extended for takeoff.
The FAA also said that the Boeing must show that, during flight, the wingtips can never be accidentally retracted, and that no subjected force can unlock the mechanisms.
Furthermore, they said that, during testing, the wings must be able to withstand up to a 75mph force on the ground.
These conditions come following the FAA’s concerns over the safety of the wingtips, as they will have to fit in with the operational capacity of airports around the globe.
