Narrative:

We had already completed a flight earlier; and sat for a couple hours in the FBO. We were then told to head to the hotel. As I started to put in the security seal info; a new brief came across to ferry the plane. I turned around and started to get the plane ready to fly again. Reconnected batteries and took the covers off! I met up with the first officer in the FBO to go over the flight. We went back out to the plane. The first officer went inside; got the inside ready; and I did my walk around.on the ferry flight at 16000 ft and at 340 kts indicated; we had autoslats came out; stick shaker went off; and autopilot disconnected. This whole incident didn't last more than 2 seconds. The flight continued without further incident. There was absolutely no indication of anything wrong before this event. Upon landing and accomplishing the post-flight shutdown; [the first officer] found that there was one aoa (angle of attack) cover missing.maybe if I did a better; more thorough walk-around; I would have caught a possible cover left on. From talking with maintenance and other pilots I'm not completely sure a cover would have caused these issues; though I'm not certain. Maybe the aoa probe covers should be tied in with the pitot covers.

Title: CE-750 flight crew experienced a momentary stick shaker; autoslat deployment; and autopilot disconnect during cruise. A missing angle of attack vane cover discovered on post-flight led to speculation that the inflight malfunctions may have been caused by a covered AOA vane.
