...If you want to go down the "just follow the rules" path, why bother to teach aerodynamics at all to student pilots? Just tell them "As you are slowing down, once it starts to shake around 20 kts you will need more power until you are really close to the ground"
OK then, I'd like to know how the Vne limit came to be in R44.
p.s. helicopter shaking as you slow down to 20 knots, that's a Robinson thing is it? The helicopters I fly don't shake, and if they do, it gets grounded for rectification.
