The Federal Aviation Agency (FAA) has ordered airliners flying the Boeing 787 Dreamliner in the United States to periodically reset the power to aircraft. This is to avoid a glitch which causes all three flight control modules on the 787 to stop working on while the aircraft is in the air.
According to an airworthiness directive issued by the FAA, "all three flight control modules on the 787 might simultaneously reset if continuously powered on for 22 days."
If this does happen when the 787 is flying, the FAA states that it "could result in flight control surfaces not moving in response to flight crew inputs for a short time and consequent temporary loss of controllability."
So in short, Boeing 787 pilots must basically reset the power systems of their people carrying flying machines regularly to ensure that the flight control computers don't reset while the plane is flying.
This in turn could lead to the pilots losing control of the plane which in the worst case scenario could end up in a crash.
In a statement to the Seattle Times, Boeing stated that it is working on a software update that will fix the glitch and that it had already recommended the reboot safety fix to 787 operators two months earlier. The software update to fix the flight controller reset issue is expected to arrive in the second quarter of 2017.
Multiple airline operators across the world have ordered a total of 1,208 units of the 787 Dreamliner from Boeing, out of which 480 are already in the air.
In India, the national airline Air India and private operator Jet Airways have ordered 27 and 10 units of the long range jets respectively. While Air India has already received 21 of its jets, Jet Airways is yet to receive one.
