I'm surprised no one has yet taken a stab at defining pilot tasking lists. So I'll go ahead and kick off some ideas. Communications for example.
Most pilots can fly and talk at the same time.
An onboard sensor scan, or switchology change which is not a stick or throttle actuated button would preclude a flight path change adjustment as the pilot is heads down for that moment and unable to be cued to events outside his focus. Lets break-down pilot actions to fundamentals. Shift visual focus 2. Internal scan of threat warning display. Interpret information from internal scan.
