Abstract:  To detect factors of affecting stall characteristic and stability of aircraft, slot parameter of outboard slat, separation face of inboard slat and fuselage, slot between slat and pylon, and slot parameter of flap were investigated. The results indicate that, root and tip of slat may affect pitching moment characteristic, slot between slat and pylon may improve lift coefficient, but no contribution for pitching moment characteristic, and, adjusting deploy angle of flap may not improve separation characteristic on main wing, because effective camber of wing is not changed.

Key words: civil aircraft, high lift device, stall, instability, pitching moment
