My airplane requires acceleration down the runway
Say your manual says rotate at 70 knots, say there is 70 knots of wind, what acceleration is there in order to rotate? Ridiculous example I know, but go back to my post re helo take off in 60 knots of wind. Turning downwind with 74 k climb speed meant our ground speed went from 14 to 134 knots. No acceleration applied to the airframe or pilot, as any accelerometer on the aircraft would tell you, for the simple reason an aircraft is operating, as I said, with respect to the airmass, not the earth.
Have a read on INS and in particular the frame of reference by which it works.
