That was me! So the system shows that sawtooth pattern to indicate: "This
sensor is working, but is reading zero"? Sounds like a good idea, just surprised
nobody has mentioned that - maybe a little-known characteristic?
Unfortunately I cannot answer if this is by design or not, I've seen this when testing installations, once valid data was received the plot was normal, again I am no FDR analysis expert, just what I have seen during installation testing.
EnchevEG - can you backup claims that the FDR plot is fake? Must admit it did for a nano second cross my mind too, mainly because it was released so quick and also (as many others have said) it just messes with my head to think they shut the wrong motor down, all the indications/warnings were there for a #2 engine problem.
In the cockpit were six eyes, all able to see #2 Engine Flameout CAS and #2 engine TQ, ITT, NP & Fuel flow indicators.
It beggars belief!!
