Greetings,
I agree with you that the optimum Profile is very seldom matching the ATC environment, but this is Airbus Aerospacial specification, and there is nothing we can do about it, on the other hand it saves money if you stay managed all time.
TOO STEEP PATH under the conditions you have shown is a bit curious, I need to have a snap shot of your MCDU, distance , speed and altitude of the waypoint before 8000 feet and after 5000 feet, spped is important. as well as your cabin altitude rate settings on the MCDU before TOD, if you can add the wind it will be perfect, E-Mail that to me and I will be able to see what is happening. Legacy FMS excluded of course.
