This application presents an unpowered glide analysis of a Cesna 172 aircraft. An aircraft with no engine power will glide to the ground. The best glide angle is the flight angle at which the airplane will travel the greatest distance, and occurs at the maximum lift-to-drag ratio. For the parameters used in this application, a Cesna 172 aircraft has a maximum lift-to-drag ratio of 10.6. This means an unpowered Cesna 176 will fall 1 m for every 10.6 m of flight. This application also calculates the best glide velocity, drag and lift coefficients, and the dynamic pressure. Reference: "Performance of Light Aircraft", Lowry, J.
