Take off acceleration is reduced, I´m sure.
If a body attains 180 MPH from zero, in a given distance, then attains only 150, in the same distance, for the same conditions, the acceleration has decreased.
Since airplanes are not accelerating as before, if one engages auto pilot level, Auto pilot than noses airplanes down, to attain adequate speed for level flight.
It may happen that for conditions other than take off runs they behave differently.
