My Answer
I asked if anyone could tell me of any advantages to this vertical profile. I guess for the pure flying side there are none, but it is clear that HEMs have a need for such a profile. I am sorry I do not have the rest of the FM as this profile was just shown to me by a mate, but I assume the vertical requirements will be harsher than an equivalent up and back. I guess none of us want a different profile for every conceivable departure so it is fair to replace the up and back for a towering one. Am I right?
