| Another pilot agrees: this was software
|
| "Boeing 787 to lose all AC electrical power due to generator
| control units simultaneously entering failsafe mode."
|
| The aircraft computer uptime was 248 days. It needed to be
| rebooted. Yes, it that's stupid of a software bug.
|
| A 2016 Airworthiness Directive requires "repetitive cycling of
| the airplane's electrical power system."
|
| a Model 787 airplane that has been powered continuously for 248
| days can lose all alternating current (AC) electrical power due
| to the generator control units (GCUs) simultaneously going into
| failsafe mode. This condition is caused by a software counter
| internal to the GCUs that will overflow after 248 days of
| continuous power. We are issuing this AD to prevent loss of all
| AC electrical power, which could result in loss of control of the
| airplane.

| Every _consumer_ computer. Human-rated aerospace hardware

| Apple doesn 't build to these standards because it's
| expensive to do so, and so far consumers have been willing

| devices they can afford and that can do new things without
| requiring a five-year development program.

| How is this any different than the youtuber lawsuit? Any
| lawyers want to weigh in?
