  Chapter 11: Aircraft Performance › Takeoff and Landing Performance › Takeoff Performance

  allow the aircraft to reach the lift-off speed at a lower groundspeed, while the effect of a tailwind is to require the aircraft to achieve a greater groundspeed to attain the lift-off speed. A headwind that ... percent of the takeoff airspeed reduces the takeoff distance approximately 19 percent. However, a tailwind that is 10 percent of the takeoff airspeed increases the takeoff distance approximately 21 percent. In the case where the headwind speed is 50 percent…

  drag is much greater than the increase in rolling resistance of tires and wheel bearings in a landplane. A tailwind may lengthen the seaplane’s takeoff distance much more dramatically than the same tailwind in a landplane. Nevertheless, there…

  times, so holding the stick away from the crosswind is good practice (left aileron in a right quartering tailwind). Elevator positioning in tailwinds is a bit more complex. Standard teaching tends to recommend full forward stick in any degree ... tailwind, arguing that a tailwind striking the elevator when it is deflected full down increases downward pressure on the tailwheel assembly and increases directional control. Equally important, if the elevator were to remain deflected up, a strong tailwind…
