Boeing 787s need to be turned off and on again every 51 days to prevent 'potentially catastrophic failure' due to a glitch that results in pilots being fed FALSE data on airspeed and altitude

#1 My car sat for a week and when I started it the clock was wrong.

#2 turned off and on again

Electrical system shut down and re-energised? how is this a big deal?

#3 You used to be able to somewhat reset a GM vehicle's on-board computer by turning the ignition key on and off five times.

Wouldn't want to do this while airborne, however.

#4 ...By the time this is done, Boeing's going to be lucky if they're allowed to PAINT airplanes much less make them.

Oh, BTW - agreement the other day between DOD/USAF and Boeing on the KC-46. Boeing's going to fix that stupid remote refueling system. On THEIR dime.

#5 It sounds like a memory leak in the Operating System or an app.
What OS does Boeing use?

#6 What OS does Boeing use?

One that was farmed out to Indian developers to save money.

Get what you pay for.

#7 Airspeed and altitude might be GPS time delay calculated. Could be the constellation map just needs a cache refresh.

#8 Probably a buffer overflow, caused by inexperienced 'programmer'.(A former reporter perhaps?)

#9 To be fair, it wasn't designed for that, the problem is known, and wouldn't you want to anyways to keep the hydraulics moving?

#10 To the public all they hear from these explanations is “blah lab blah, Boeing screwed up again. Let’s fly airbus planes instead. Stop outsourcing critical stuff and doing MBA cost savings analytics on components that can get people killed.

#11 I could show them how to rig up a RaspberryPi to do that without wasting pilot time.

#12 I think it's not good for any machine to sit idle for too long. And, as far as memory leaks go, Microsoft has been as guilty of this problem as any other software company.

#13 Barring a runtime that does garbage collection, every development organization has had memory leaks.

The really unlucky ones get memory leaks in environments WITH garbage collection...

#14 The problem with garbage collection in a real time system is that you do NOT want it to run at the wrong time - say during landing.

#15 I'd think twice,boarding a plane with jumper cables hooked up on the tarmac.

Spring ahead, fall back. :-)
