Question: The plot at the top of the following page shows data for publicly available maximum thrust versus maximum takeoff weight for a wide range of twinengine business jets. Planes from the "very light jet" market are at the lower left, and the 737 business jet is at the upper right. Show that the maximum lift-to-drag ratio for all of these aircraft is approximately 6, assuming that they can take off with one engine out. You should assume that the takeoff roll is horizontal and that enough lift is generated to begin accelerating vertically. Similarly, assume that the takeoff roll at liftoff has negligible acceleration- that is, nearly constant speed.
