To support the same weight, the plane needs to move faster through that air.</p> <p>The animation below compares identical planes at two runway elevations. Select <strong>Animate acceleration</strong> to start both at 15 m/s and increase their speed together. Each yellow runway-distance counter stops at liftoff. You can also change the airspeed and the high runway&rsquo;s elevation directly.</p>
