| Abstract: | This paper presents an engineering method to determine the minimum unstick speed with the aircraft's take-off equations of motion and provides the emulational results,according to the Federal Aviation Regulations 25.The method of modifying the minimum unsticks speed for airplanes having the limited pitch control authority is also given referring to the method of modifying the stall speed.In addition,the effects of rotation speed and one engine failure on the take-off performances are also analyzed.The methods mentioned can serve as a reference for flight test researchers. |

| Keywords: | minimum unstick speed airworthiness one engine failure take-off performance |
