Boeing 777 Computer Glitches?

Question

Just did some research about the cause of crash of the BA 038 772, found interesting stuff about the 777s computers/autopilot.

anyone have more info or details or new archives, anything?

Much appreciated.

Answer 1

While we are are all interested in learning;

Pitot's tube (Webster's dictionary)

A bent tube used to determine the velocity of running water, by placing the curved end under water, and observing the height to which the fluid rises in the tube; a kind of current meter.

Same principle applies to air.(all fluids in fact)

Let us hope the ground crew uncapped the Pitot and not the Peeto instead.

Answer 2

BA 038 lost power because of the computer tied to the FADEC system. When the pilot pushed the throttle forward, nothing happend.

The software is faulty.

This short landing should be a wake-up call for the FAA to change how software is certified. DO178 compliance cost companies millions but, it doesn't require line-by-line scrutiny of code.

There is a lot to go wrong..go wrong...go wrong...go wrong...

Joel K,  Thanks for the link. That is interesting reading. Do you know if the valves themselves report back to the data logger on their position (which was reported as fully open)? or if just the fact that a command was sent is what is recorded? I'm not familiar with the signals to/from the valves.

Answer 3

Shh... and keep mum abt those GE engines too.

Answer 4

well, my opinion why that plane went down is, probably aircraft didnt have enough speed, or ADI didnt show the correct speed, and plane was left on autothrottle and autopilot, and autopilot was feeding up with the wrong information from ADI, and plane most likely stalled. The reason maybe plane had incorrect speed could be because peeto tubes were blocked.

EDIT: To the guy below me, yes its Pitot Tube and my mistake, but Pitot tube is not something that u described. Aircraft use pitot tubes to measure airspeed which transfers to ADI, and in each aircraft there are two Pitot tubes, one from captain side and one from First officer's side, probably the captain's side pittot tube was blocked and F/O's wasnt

Answer 5

Sorry, no conceivable software problem can explain the cavitation found in the fuel pumps during engine disassembly. BA 038 was not brought down by a computer or autopilot problem. Fuel flow problem is looking much more likely. (Possibly due to low air temperatures causing some fuel to freeze or thicken in the fuel lines.)

Read the 'engines' section of the report below carefully. The software opened the fuel valves, the fuel did not flow.
