Originally posted by awblain... however, on the ground the aircraft pivots not around somewhere in the middle above the wing box, but on the wheel-runway contact point; hence, more thrust should act to plant the nose down more firmly.
???? Surely the engine thrust line couple is below the C of G which will produce a nose up torque.
During braking, the C of G is above the drag line of the wheel contact point, so then there is a nose down couple to "plant the nose down more firmly".
