When the aircraft was yawed, it was found that positive yaw angles resulted in a violent rolling moment and wing separation was initiated at smaller angle of attack. For the negative yaw condition, the separation occurred at 2-3 deg of angle of attack later, and the resulting rolling moments were within control limits. The above finding suggests that aircraft similar to the one tested, under positive sideslip condition, are likely to face a stall-spin entry when performing, for example, a low-speed final left turn with excessive rudder deflection before landing.
