Reboot helps against power failure: Software errors in the Boeing 787 Dreamliner – Heise Newsticker



An error in the software can cause in Boeing 787 Dreamliner all the electronics fails. The solution to the problem sounds like the Council of hotline staff.

“Have you rebooted the computer?” What sounds like the flat response of support personnel, is the solution for potentially dangerous technical problems of passenger aircraft Boeing 787-8 and -9 aka Dreamliner.

According to a warning from the US Aviation Authority FAA, a software cause errors cause the entire electronics of the aircraft fails spontaneously and the pilots lose control.

Boeing discovered the bug in laboratory tests. He causes the generators of the Dreamliner (about every 8 months) automatically drop all 248 days in the so-called fail-safe mode, because an internal counter overflows. The generators so schlaten off to prevent further damage in case of failure.

The same would happen with all generators on board when they were launched at the same time. Then only ensures a ram-air turbine emergency power supply; until it starts, a battery supplies the necessary energy. Some hydraulic parts run limited or not during this period. Dangerous for the situation would be especially during landing or takeoff

Routine Maintenance

The solution to the problem is simple. The system must be shut down periodically. According to Boeing’s records have so far all the Dreamliner, which are in use, periodically turned off and on again – that was part of the routine maintenance

More recently commended Boeing customers, at least every four months down the system.. Thus, there would be no immediate danger that in one of the planes of a power failure. The manufacturer is currently working to resolve the software error.



Error Messages

On the other hand, occurred in the first 787 repeatedly on many small problems after a restart of the aircraft, which resulted in some airlines the machines operated unusually long without rebooting. These errors are valid but as eradicated.

In the past repeatedly occurred Battery problems Dreamliner on. What even that caused the aircraft had a long time remain on the ground. (HCz)
