If there was not, well maybe AA should have made a memory item for TCAS or had a procedure for TCAS which clearly says AP off, FDs off, etc.
That’s beside the point. It’s not about policy in a manual, it’s about an inversion of the instinctual reaction of how to control the airplane in a sudden situation.
It’s like you’re driving a Tesla playing around with the Autopilot (to make the analogy maybe a little too on the nose) and when it suddenly starts veering toward a wall, instead of going “okay, that’s enough” and steering it away from the wall with the steering wheel (like any current driver would), you try to fiddle with the automation controls to get it to go the right way. Seems unthinkable to us, but I bet we’ll see this scenario in reality sooner rather than later.
When the “Autopilot” becomes the rule rather than the exception, and someone has been depending on it from the ground floor of their relationship to the vehicle, trained reflex (especially under the tunnel vision/task saturation of a situation suddenly turning wrong) will revert there.
