An object of the present invention is to provide a turbulence avoidance operation assist device that automatically generates an optimal trajectory of emergency avoidance and reports this trajectory to a pilot when distant turbulence is detected during an aircraft flight. The turbulence avoidance operation assist device in accordance with the present invention includes: means for detecting the presence of a danger region such as a turbulence region ahead of aircraft in a flight direction; means for representing the danger region as an assembly of rectangular solids when the detection means recognizes the danger region, and generating a flight trajectory by a local optimum solution of an avoidance trajectory using a convex quadratic programming method in which deviation from a reference trajectory is the smallest on the basis of an initial estimation solution obtained by a semidefinite programming method; and means for reporting the flight trajectory to a pilot.
