Just as Autotrim acts over longer term than Stick input (elevators), is there a relationship between the pilots' knowledge of this and an attempt to maneuver without its help? It seems there may be a conscious effort to avoid changing the AoI of the aircraft by using quick inputs, followed by opposites?
Has anyone explained this rapid use of the SS? Does it relate to a 'workaround' of the trim? It is especially odd considering the altitude, and airspeed, to see large and rapid stick displacement. Any Bus pilot care to address?
