I'm sorry if the following aspect has been discussed yet:Airport at see level; fmc reduction clmb-1 thrust, fmc clmb thrust at 1500 feet; flaps 5 t/o, lnav engaged, mcp altitude selector at 10000 ft. If I engage a/p between 400 agl and 1500 agl flight level change engages too, and I red N1 in the a/t modes of the flight mode annunciator, so I presume the plane enters climb thrust before reaching 1500 ft. Is this correct? For me in this configuration the best way to t/o is: starting flaps retraction at 1500 ft, engaging a/p at 3000 (with flaps up) and then flight level change or vnav. Is there a right way to engage a/p earlier in the t/o phase?Thanks.Igor
