Swiss tapes its Boeing 777-300ER with a special foil. This should noticeably reduce fuel consumption.

The Swiss carrier covers its 777-300ER with AeroShark films. The foil developed by Lufthansa Technik and BASF imitates the properties of a shark skin and is intended to reduce frictional resistance in flight. With a total of around 950 square meters of riblet film, the modification of the "long" Boeing 777-300ER will be even larger than the around 800 square meters on the Boeing 777F of AeroShark's first customer Lufthansa Cargo. “Calculated for the operational profile of the twelve Boeing 777-300ER at Swiss, this means annual savings of more than 4.800 tons of kerosene and around 15.200 tons of carbon dioxide, as much as is usually produced on around 87 long-haul flights from Zurich to Mumbai,” writes Lufthansa Technik in a press release .

"Reducing the ecological footprint is one of the biggest challenges for the aviation industry, and CO2-neutral flying by 2050 is an important strategic goal for Swiss," said Swiss CEO Dieter Vranckx. “It is very important to us to actively promote the use of new technologies and to invest in them in a targeted manner. We are pleased to be able to make another important contribution to more sustainable travel in the future as the world's first passenger airline with the innovative AeroSHARK technology on our Boeing 777 fleet."
