I've been pondering about the autopilot and auto thrust response to a large and sudden up gust.

The altitude hold would attempt to maintain the selected altitude by selecting a lower attitude and the auto throttle would reduce power to maintain airspeed.

Quiet often after a large gust in one direction there is a reversal of the original gust.

This might lead to a rapid reduction in airspeed with thrust already at at minimum.

Severe turbulence would require pilot intervention to set cruise attitude and power but in the event of a sudden massive gust we have all the potential ingredients for an upset of some sort.
