British Airways is to paint a Boeing 777-200 aircraft with a fuel-efficient coating after positive results from tests using an Airbus A318.
The coating, which is known as 'Triple0', creates a polarising bond with the aircraft surface structure and achieves a "perfectly smooth" finish, said the carrier, which improves aerodynamic performance.
Year-long tests with one of the two BA A318s operating transatlantic services from London City to New York showed the twinjet consumed less fuel than the one without the coating.
BA said the 777 will be similarly coated to extend the trial period and added that it looked to save more than £100,000 ($154,000) over the duration of the tests with the larger aircraft.
"We have been exploring a number of initiatives to improve fuel efficiency," said BA director of engineering Garry Copeland. "[This coating] not only delivers a significant saving, it also improves aircraft appearance."
BA said the coating - which lasts about two years - has fringe benefits including less-frequent cleaning and painting.
