"After 80 kts and before V1, we'll abort for engine fire, failure, loss of directional control, master warning, or loud yelling from the cabin." Is that how the brief goes?
Not saying you might have actually aborted, just some of my thoughts. A high speed abort is a serious and potentially dangerous maneuver and, in my opinion, should not be attempted soley due to some yelling from the cabin. Especially if you have an FA to "deal" with the issue in the back. In my airplane, the pax have direct access to the cockpit, so depending on the nature of the yelling and other physical movements, the situation may be more serious than if we had a locking bulletproof door.
