The FAA handbook has a lot of people still believing that "flapping to equality" is happening all the time, and that the advancing blade is flapping up in forward flight. Never mind the reality of looking at the disc tilted forward, that is just a distraction. Sure, flapping does happen as soon as you move forward, but the pilot puts in forward cyclic to stop it, and continue moving forward. Go faster, need more and more forward stick to keep that disc tilted forwards.
