Well, i use it as a backup. Doesnt mean that i cant fly but the fmc calculates a pretty good descend profile into fields which have no restrictions. so i fly approaches with nearly no power. ive seen fellows who dont like this feature, always ending up with setting much more power or doing about 6-8 nm level flights. well, they planned their descend on their own. but used much more fuel. good airmanship is important but hating computers in out time is stupid especially in modern airline cockpits.
work together, not against the computers. And keep it simple. Thats my message
howdy
