Airbus has called on the aviation industry to set a minimum 18-inch seat width.
The manufacturer today revealed research into the impact that seat width makes on passenger comfort during long-haul economy flights.
And it has now called on airlines to enforce a minimum width of 18 inches (45.72 cms).
The study, by The London Sleep Centre, used polysomnography to record every standard physiological sleep measurement – including monitoring brainwaves, eye, abdominal, chest and hip leg movement – on a selection of passengers.
Researchers found that a minimum seat width of 18 inches improved passenger sleep quality by 53 per cent when compared to the 17-inch standard, which was first introduced in the 1950s.
