> Engineers inspected the engines and could find no reason for the dual failure. With the post-inspection finding nothing to cause the engines to fail, engineers are saying the likely cause for the shutdown is a software issue onboard the aircraft.
Very interesting that
a) one of the first checks by engineers is not an evaluation of the software "log" or similar. either they have a specific checklist they MUST go by and that checklist doesn't include software log, and/or such log is simply not available to them.
b)"likely cause"? again, why don't engineers have easy access to a software event log?
I can very well imagine such instrumentation of software caused events not even existing for the shit apps we build, but for safety critical systems in an airplane? The log MUST exist. Why don't engineers on the ground have easy access to it. The software is integral these days.
And where would you store these logs ?
I'm sure the engine stores its faults somewhere, but i'm not expecting more.
You have to realise that you can run safety critical software on certified microcontrollers, which have usually like 10 mb of flash. Moreover it is an aicraft, and worse it is an engine, so I guess that the mechanical requirements are insane (able to withstand a lot of vibrations, operate in -60 to 160 deg celsius, withstand cosmic rays). A samsung ssd does not fit the bill.
It's probable however that the aircraft communications lines are recorded in a black box, but you can only see the data exchanged by the ECUs, not the relevant internal variables telling you about the bug.
Mind you i'm not working in the aicraft industry, my assumptions may be false, but my guess is that the engine controller is on the engine itself.
