Eddie Sez:

And now for something a little different. We all know the vital role accident investigators from the National Transportation Safety Board and other agencies play AFTER an accident has happened. Their primary role is to learn from the past so that we may avoid future accidents. All that is great.

But what role do we line pilots have in all this? I contend that we would be the perfect PRE-Accident Investigators. We should be able to learn from everything at our disposal so that we can investigate the causes of accidents BEFORE they happen to prevent them in the first place.

I think a perfect case in point is the case of what I call the "Ambiguous Gulfstream Auto-Throttles." If you aren't a Gulfstream pilot, I am betting you could find a similar system on your airplane that could use some good PRE-accident investigation.

What follows comes from a speech I gave in June, 2016. You can view this presentation here:
