Air Baltic A220 Engine Shut Down – Why Did It Happen?Last week, an Air Baltic A220 crew had a dual engine shut down, when they landed. Why? A Mentour reader kindly gave us some key information! (mentourpilot.com) More...

I don't understand why it was necessary that the "automation" took it upon itself to shut BOTH engines down once it had detected that the a/c was on the ground. WOW switches have been known to fail. The possibility of a faulty WOW sensor/s then having the potential to hand you a double engine shutdown whilst airborne. That couldn't happen on an F28!
On-ground is probably determined by multiple sensors, including altimeter and ground proximity sensors, not just the weight-on-wheels.
seems the more we automate the less we aviate. Well, I'm being a bit facetious, threw that out because it sounds funny. Still, I do wonder (and worry) that so many routine functions are being automated. Why? Because as the software code becomes ever larger it also becomes ever harder to accurately model all interactions and outcomes.
I am an engineer and I find this article alarming. If I understand correctly, some modern jet engines are sufficiently prone to run-away that the aircraft in which they are mounted have an automated system to cope with the event. That system is only prevented from shutting both engines down in flight by a switch in the landing gear. Murphy is watching this balancing act with a smile on his face.
Unless someone pulls the QAR nobody will know how many over temps (hotstarts) were gotten’ away with?
I was referring to the days of ‘yore,
As I mentioned on a previous comment, on-ground is probably determined by multiple sensors, including altimeter and ground proximity sensors, not just the weight-on-wheels. The control laws are complex but exhaustively tested.
