The FCTM also states that if an automatic approach is being conducted then no wind additive need be included on top of the Vref+5 normal approach speed as the Autothrottle incorporates gust protection...for anyone who has every operated the aircraft in particularly gusty conditions I would be interested to hear their opinion..I prefer to fly manually as the automatics have a lag element when reacting to airspeed fluctuations which in some cases can require very large thrust increases to maintain fly speed and consequently a subsequent manual disconnect can leave certainly leaveyou with extra work to do.
