Then, I got ready to land the plane
Because it wasn't a real emergency, we did a few things differently.
For example, our pilot disabled the feature that communicates with air traffic control, since we didn't want to send out a false emergency broadcast. Also, because we didn't want to interfere with normal air traffic, we waited to push the button until we were in a scenario where it was obvious which airport, runway, and direction the auto-land system would choose.
But other than that, this was, the system behaved exactly as it was designed to.
