I have to agree. If you're saying "the software is working to spec, but the specs are bad," then you're still describing a software problem.

This is a pretty bold statement. The spec includes many non-software related features.

In aerospace, lack of proper requirements in the flight software would be a system engineering problem... a semantic difference really, but important nonetheless.
System engineering and validation has a metric ton of 'tools' to catch bad system design and improper algorithm implementation...
I really question what the hell happened here: - Did they just pencil whip the FMEA on this or what? (failure mode and effects analysis)
- What happened with the Hardware-in-the-loop flight simulation when they tested the scenario where the AoA sensor givesg spurious data, both high and low (but especially high)? I mean... they did test this, right?
