A320 : fuel efficient descent
Surely the resulting managed speed target depends on perf and idle factors. But no matter how you look at it: an idle green dot DESCENT at max L/D will lead to the lowest SFC and thus trip fuel, regardless of engine type etc. This should coincide with CI=0, but on the A320 the lowest econ des speed is limited to 250/270.
