Actually, if you want to get down to it, it is airport specific. Given that the normal technique is to use Min EPR. But, airports such as New Haven, rwy 15 at Burbank, etc, all recomend using a max flex technique. I was simply saying that on a day to day basis it is probably best to use a flex quiet climb and mind your airport specific guidance. I guess it seems that maybe I have been paying more attention than you my friend.
