I don't know how many times you have activated approach and yet you failed to notice what happens. When you activate approach the speed target Vapp appears in magenta at the bottom of the speed tape and that is what you are supposed to check. Similarly when you reach acceleration altitude your speed target becomes 250KTS and is shown in magenta on top of the speed tape. Obviously when you reach the target it won't be shown there any more. Spend some time understanding the system before ridiculing the manufacturer's recommendation. And what else is included in your full of inaccuracies?
