Whenever I perform a takeoff in the 737-800, I end up striking the tail on the runway. I have tried rotating slowly and and less steeply but when I do this my plane never seems to get of the ground or if it does, it ends up touching down again. I am also sure that I use the right amount of flaps (5 or 10) and I rotate between 130-140 knots. Can anyone help me or tell me if I am doing anything wrong.
Thanks in advance. :-)
