The invention provides a civil aircraft flight test subject arrangement and optimization method, which comprises the following steps: calculating an objective function value and an objective function value of a subject sequence corresponding to each chromosome after complete mutation operation and crossover operation; executing a selection operation by adopting a tournament selection mode to obtain a new population; continuously repeating until the number of iterations reaches the maximum number of iterations, outputting an optimal chromosome in the population as an optimal subject sequence; and performing subject arrangement for the subject sequence, and calculating a target function value to obtain an optimal subject arrangement result and an optimal target function value. According to the method, the test flight subject arrangement result meeting each constraint condition is obtained, the subject arrangement result is optimized by adopting the genetic algorithm and by taking shortening of the test flight p
