I don’t get this thinking, if you’re in the bandaid making business, maybe make sure it doesn’t cause an infection ?

In this case the software was developed to compensate for the system characteristic,it did not fully do that. Of course, it is immensely frustrating that software is always called upon to the papering up, but that is another issue.

Sure, I'm not necessarily endorsing the thread.

I'm just saying the existence of an in progress software patch in no way contradicts the thread itself.

It's part of the premise of the thread itself.

I was looking at it from the narrow view that it was to do A (the papering over), and it did not do that (fully).

On second thought, it’s more a systems engineering issue not to take that case into account. Software engineering doesn’t get off scot free though, as they are an important voice.

With the presumably tight engineering controls that are practised, I can speculate that it may have fallen into “the pilot disables and takes over control” branch. The gap would then be that they did not think that the airlines would be given the option to “not” install the sensor failure warning.
