Boeing started with the installation of folding wingtips for the 777X. The   
   manufacturer has released a photo this week showing it clearly. The   
   collapsible wing end will fly for the first time on a test aircraft in March   
   2019.   
       
   The mechanism allows Boeing to give the 777-8 and 777-9 larger wings, but the   
   aircraft at the gate do not take up more space than the previous generation   
   Triple Sevens. The aircraft have a wingspan of 72 meters in the air and 65   
   meters during taxiing and parking.   
       
   As a result of the larger wings (and new engines) the 777-8 and 777-9 have to   
   be about 12 to 13 percent more efficient than their predecessors, the 777-200   
   (ER) and 777-300 (ER). Launch customer Emirates expects to receive the first   
   777-9 in 2020.
