On the B747-400, the TO/GA initiation is means of starting the go around, dependent on the company SOPs there will be a reselection to other modes - e.g. at 1000' agl select FL CH and hit the THR switch (to reduce to CLB power) or VNAV in place of FL CH. But if the the aircraft leveled at ALT capture and , the autothrottle mode would be at THR will the power increasing....can anyone explain to me why so? And what is the meaning of "light extinguished/thrust limit function" and "light illuminated/Auto throtttle mode function"....totally need help with why the lights are sometimes illuminated and sometimes extinguished. Thanks!!!
