Just curious pilotguy-are you a real pilot? Can't safely fly at CI400-really? What is the max CI the FMC takes- (hint-it is 4 figures so a lot more than 400)-which is within the certification envelope of the aircraft-ie already has a safety margin built in. What is the Mmo? If we are going to complain-which needs to be done-at least do it based on facts-otherwise all arguments are invalid. It doesn't matter how many good points you have-as soon as you sprout BS you are discredited on all.
