Tired A380 pilots say aircraft is too quiet: Pilots who are trying to catch some sleep between shifts on the Emirates Airbus A380 have complained that noise from the cabin keeps waking them up, because the airplane itself is so quiet they can hear all the crying babies and flushing toilets. "We're getting a lot of complaints. It's not something we expected," Emirates spokesman Ed Davidson told Flight International. "On our other aircraft, the engines drown out the cabin noise. [On the A380] the pilots sleep with earplugs but the cabin noise goes straight through them." The problem is most noticeable on the Emirates A380s because they chose to put the crew-rest area at the back of the main cabin, while Singapore Airlines and Qantas have placed it right behind the cockpit. Extra insulation is not a solution because it would add extra weight, Davidson said. The airline may experiment with lightweight noise generators that would create ambient sound to mask the cabin noise, according to Flight International.
