Hey, soo i have been noticing this issue while i take off…when i take off on a widebody aircraft with normal - heavy weight…during rotate i lift the airplane up but it dosent come off the ground…i have to gently wait for a bit and lift it off the ground to avoid tail strike…for eg. i took off on a a330 with normal weight and 1 knot wind. Throttle is set to 85%. Flaps set to 1+F. The rotate was around 160 knots. Am i doing anything wrong here ? I dont use trim…is that the issue ?
