What the heck is “Automation Surprise”?

Well, as it turns out:

JetStar Over two decades ago, Wiener (1989) described the concept of ‘automation surprise’, where the reaction of flight crews to the unexpected actions of an automated aircraft system was, at times; ‘What is it doing? Why did it do that? What will it do next?’ (Sarter and Woods, 1995; Sarter, 2008). Aviation safety occurrence reports worldwide indicate that such problems still occur in air transport aircraft today.

Sure JetStar offers cheap flights.  But they’re cheap for a reason.
