High-lift, mild stall wings are attractive for development of small and medium size UAV. This is especially true for evaluation of configurations with increased level of parasite drag, where optimum endurance performance is realized at high loitering lift coefficients, leading to a very demanding requirements for maximum lift. High-lift, mild-stall wings allow relaxation of imposed speed safety margin and extension of allowable range of flight lift coefficients.
