I know I should just let this thread die at this point but what the hell I have nothing better to do so I'm going to ask another question:
Why does Airbus make us use the Vref figures in the QRH when calculating Vapp rather than allowing the pilot to pull out the Vls figure from the box? One would think that it would be more precise given that it is calculated for the exact weight and CG. That is of course if its available to the pilot, no problem with having a back up chart of course.
