Since you are quite the all knowing of all things to do with helicopters....care to enlighten us about other limitations that apply to Slope Landings? There are more than a few that apply and they vary by which direction one lands on a Slope you know.
There are different limitations imposed by the design of the aircraft as well too....but then I am so sure you know all that anyway....but just left them out for brevity sakes!
If one lands with the nose pointed uphill...where does Lateral Cyclic enter into the equation?
If you are going to play the "Troll"....at least be a reasonably educated Troll will you?
