Abstract Civil aircraft load design regulations generally require load calculations for various combinations of weight, center of gravity, moment of inertia, speed, and altitude etc. Considering different maneuvers and gusts, the number of load conditions will reach tens of thousands. If we consider the load of each point in the time history of the simulation, the number of load points will be unacceptable. It is very difficult to filter out the valid data from a large number of databases and get the critical load of the aircraft. On the one hand, if the selecting method is not precise enough, it may cause some critical load conditions to be missed, which will affect the structural safety of the aircraft. On the other hand, if the selecting method is too complicated, it may lead to too many critical load conditions and some invalid data, which will influence the efficiency of the aircraft design. Based on years of engineering practice, this paper proposes a kind of efficient and reasonable selecting methods for civil aircraft load calculations, which has been verified in several types of aircraft design.
