Airbus? Well, all bets are off if you're flying a Scarebus.

You must be talking about Flight 593, with kids in the cockpit. Substantial
movement of the control column by one of the captain's kids visiting the
cockpit triggered a cancellation of roll-mode AP control, which in the
Scarebus is not audibly annunciated. It didn't take long for the pilots to
notice something was amiss, but by the time they figured it all out and got
the airplane under control, they were too low, and they crashed.

The mere fact that the captain let his kids touch the controls tends to imply
that the crew was incompetent to begin with.

Next, look up the Century series of autopilots. I'll guarantee you that they
don't give any audible alert when they disconnect. Don't even try to argue
this one since I have one in my aircraft.

Are you flying a 747 or an A380?
